Answer: -47 - 48x
Step-by-step explanation: When you first take a look at this problem, it's tempting to want to subtract -7 - 8 to get -15 and then distribute the -15 through the parentheses.
You wouldn't want to subtract however before you distribute because the distributive property is a form of multiplication and remember from your order of operations that multiplication comes before subtraction.
So the first thing you want to do here is distribute and change the minus sign in front of the -8 to plus a negative 8 so that you know you are distributing a -8 through your parentheses.
So we have -7 + -8 times 6x which is -42x + -8 times 5 which is -40.
Now we have -7 + -48x + -40.
Now just combine your like terms. -7 + -40 is -47 and plus a negative 48x can be written as -48x so we have -47 - 48x.
So your answer is just -47 - 48x.
Find domain and range for f(x)=x^2-2x+2
Answer:
Domain: (-∞,∞) or -∞ <[tex]x[/tex]<∞
Range: [1,∞) or [tex]y\geq 1[/tex]
Step-by-step explanation:
Given function:
[tex]f(x)=x^2-2x+2[/tex]
To find range and domain of the function.
Solution:
The given function is a second degree function as the highest exponent of the variable is 2. Thus, it is a quadratic function.
For all quadratic functions the domain is a set of all real numbers. So, the domain can be given as: (-∞,∞) or -∞ <[tex]x[/tex]<∞
In order to find the range of the quadratic function, we will first determine if the function has a minimum point or the maximum point.
For a quadratic equation : [tex]ax^2+bx+c[/tex]
1) If [tex]a>0[/tex] the function will have a minimum point.
2) If [tex]a<0[/tex] the function will have a maximum point.
For the given function: [tex]f(x)=x^2-2x+2[/tex]
[tex]a=1[/tex] which is greater than 0, and hence it will have a minimum point.
To find the range we will find the coordinates of the minimum point or the vertex of the function.
The x-coordinate [tex]h[/tex] of the vertex of a quadratic function is given by :
[tex]h=\frac{-b}{2a}[/tex]
Thus, for the function:
[tex]h=\frac{-(-2)}{2(1)}[/tex]
[tex]h=\frac{2}{2}[/tex] [Two negatives multiply to get a positive]
[tex]h=1[/tex]
To find y-coordinate of the vertex can be found out by evaluating [tex]f(h)[/tex].
[tex]k=f(h)[/tex]
Thus, for the function:
[tex]k=f(1)=(1)^2-2(1)+2[/tex]
[tex]k=f(1)=1-2+2[/tex]
[tex]k=f(1)=1[/tex]
Thus, the minimum point of the function is at (1,1).
thus, range of the function is:
[1,∞) or [tex]y\geq 1[/tex]

Step-by-step explanation:
Given equation is:- [tex]C=35n+40[/tex]
where, C=Cost in dollars, n=hours.
Now, Amy charge $40 for service call and $35 for per hour service.
So,
For 0 hours:
[tex]C=35n+40[/tex]
[tex]C=(35\times 0)+40[/tex]
[tex]C=0+40[/tex]
[tex]C=40[/tex]
Therefore for 0 hours Amy charge $40.
For 1 hours:
[tex]C=35n+40[/tex]
[tex]C=(35\times 1)+40[/tex]
[tex]C=35+40[/tex]
[tex]C=75[/tex]
Therefore for 1 hours Amy charge $75.
For 2 hours:
[tex]C=35n+40[/tex]
[tex]C=(35\times 2)+40[/tex]
[tex]C=70+40[/tex]
[tex]C=110[/tex]
Therefore for 2 hours Amy charge $110.
For 3 hours:
[tex]C=35n+40[/tex]
[tex]C=(35\times 3)+40[/tex]
[tex]C=105+40[/tex]
[tex]C=145[/tex]
Therefore for 3 hours Amy charge $145.
For 4 hours:
[tex]C=35n+40[/tex]
[tex]C=(35\times 4)+40[/tex]
[tex]C=140+40[/tex]
[tex]C=180[/tex]
Therefore for 4 hours Amy charge $180.
For 5 hours:
[tex]C=35n+40[/tex]
[tex]C=(35\times 5)+40[/tex]
[tex]C=175+40[/tex]
[tex]C=215[/tex]
Therefore for 5 hours Amy charge $215.

Kyle’s parents told him that for every 5 hours of homework or reading he completes, he will be able to play 3 hours of video games. His friend victor’s parents told their son that he can play 30 minutes for every hour of homework or reading time he completed. If both boys spend the same amount of time on homework and reading this week, which boy gets more time playing video games
Kyle will have more time to play video games
Solution:
From given question,
Kyle’s parents told him that for every 5 hours of homework or reading he completes, he will be able to play 3 hours of video games.
5 hours of homework = 3 hours of video games
Victor’s parents told their son that he can play 30 minutes for every hour of homework or reading time he completed.
1 hour of homework = 30 minutes of playtime
Suppose if victor spends 5 hours doing homework or reading, then he could play,
5 hours of victor homework = 30 minutes x 5 = 150 minutes of play
That is,
150 minutes = 120 + 30 = 2 hours 30 minutes
This 2 hours 30 minutes playtime of victor is less than kyle playtime (which is 3 hours )
So Kyle gets more play time
A computer company has a special going in which all customers receive a free monitor and scanner with the purchase of a new computer. It costs the company $393.29 to make each computer, $151.44 to make each monitor, and $46.39 to make each scanner. The computers are then sold, with the free monitor and free scanner, for $1,196.91 each. Approximately how much profit will the company make if 408 customers take advantage of their special? (Round to the nearest 50 dollars.) A. $300,000.00 B. $550,000.00 C. $240,000.00 D. $380,000.00
Final answer:
After subtracting the manufacturing costs of the computer, monitor, and scanner from the selling price for one unit and multiplying by 408 customers, the approximate total profit is $247,050.00, which rounds to option C. $240,000.00.
Explanation:
To calculate the profit the company makes for each computer sold at $1,196.91 after giving away a monitor and a scanner, we need to subtract the cost of manufacturing the computer, monitor, and scanner from the selling price, and then multiply it by the number of customers. The costs for the computer, monitor, and scanner are $393.29, $151.44, and $46.39 respectively. Therefore, the total cost of manufacturing one set is:
Total cost = Cost of computer + Cost of monitor + Cost of scanner
Total cost = $393.29 + $151.44 + $46.39 = $591.12
The profit for one computer set would then be:
Profit per computer = Selling price - Total cost
Profit per computer = $1,196.91 - $591.12 = $605.79
To find the total profit for 408 customers, we multiply the profit per computer by the number of customers:
Total profit = Profit per computer × Number of customers
Total profit = $605.79 × 408 ≈ $247,060.32
When rounding to the nearest 50 dollars, we get:
Total profit ≈ $247,050.00
The closest answer to this would be option C. $240,000.00.

A hotel shuttle service charges $7.50 plus $0.85 per mile . A customer hires a shuttle for a ride to the airport and the total charge is $12.60 . Which equation can be used to determine the number of miles from the hotel to the airport ?
Answer:
6.40=$12.60
Step-by-step explanation:
First, make the equation following the problem.
$7.50 + $0.85 = $12.60
Then, find the number of miles.
$7.50 * $0.85 = $6.40
$6.40=$12.60
Don't need to solve it because it is asking for the equation.
This is a linear equation problem in Mathematics. The equation to find out the number of miles for the given total charge would be 7.50 + 0.85m = 12.60. Through algebraic manipulation, it is found that the shuttle travelled 6 miles.
Explanation:The subject of this question is in the field of Mathematics, specifically under linear equations in algebra. In this problem, the customer is charged a flat fee of $7.50 and then an additional $0.85 per mile. The total charge for this trip was $12.60, and we're tasked with finding the number of miles covered for this charge.
The equation to solve this problem would be 7.50 + 0.85m = 12.60, where 'm' represents the miles. We subtract 7.50 from both sides, then we get: 0.85m = 5.1. To solve for 'm', we divide both sides by 0.85, and we receive m = 6 miles.

A cyclist rides her bike at a rate of 21 kilometers per hour. What is this rate in kilometers per minute? How many kilometers
will the cyclist travel in 2 minutes? Do not round your answers.
Answer:
Step-by-step explanation:
The cyclist's speed is 0.35 kilometers per minute. She will travel 0.7 kilometers in 2 minutes.
Explanation:The question deals with converting speed from kilometers per hour to kilometers per minute, and also calculating distance given a certain time and speed.
First, we convert speed from kilometers per hour to kilometers per minute. There are 60 minutes in an hour, so we divide the speed of the cyclist (21 kilometers per hour) by 60: 21/60 = 0.35 kilometers per minute.
Next, we calculate the distance the cyclist will travel in 2 minutes. Distance equals rate times time, so we multiply the cyclist's speed by the time: 0.35 kilometers per minute * 2 minutes = 0.7 kilometers.

You need to buy 18 rolls of film. One shop sells it for$9.95 plus 5% sales tax. Another shop $9.75 per roll and charge $15.00 to ship no sales tax. Choose the better of the two prices how much will you pay for 18 rolls of film?
Answer:
We will buy it at $9.95 plus 5% tax because it is slightly cheaper than other price
Step-by-step explanation:
$9.95 x 18 = 179.10 + 5% sales tax(8.95) = 188.055
$9.75 x 18 = 175.50 + 15 = 190.50
hence sales tax can be get back by submitting monthly return file. so the first method is cheaper than second one,
The first shop offers a better price for 18 rolls of film. You will pay [tex]$179.10[/tex]for 18 rolls of film at the first shop.
Let's calculate the total cost for each shop:
For the first shop:
- The price per roll is [tex]$9.95[/tex].
- There is a 5% sales tax.
- The total cost without tax for 18 rolls is [tex]18 rolls * $9.95/roll = $179.10[/tex].
- The sales tax on this amount is 5% of [tex]$179.10[/tex], which is [tex]0.05 = $8.955.[/tex]
- The total cost including tax is [tex]$179.10[/tex][tex]+ $8.955[/tex] [tex]=$188.055.[/tex]
For the second shop:
- The price per roll is [tex]$9.75.[/tex]
- There is no sales tax.
- The shipping cost is a flat rate of [tex]$15.00.[/tex]
- The total cost for 18 rolls, excluding shipping, is 18 rolls *[tex]$9.75/roll[/tex] [tex]= $175.50.[/tex]
- Adding the shipping cost, the total cost is [tex]$175.50[/tex][tex]+ $15.00 = $190.50[/tex].
Comparing the two total costs:
- First shop: [tex]$188.055[/tex] (approximately [tex]$179.10[/tex] without rounding the tax)
- Second shop: [tex]$190.50[/tex]
The first shop offers a better price for 18 rolls of film. You will pay approximately [tex]$179.10[/tex] for 18 rolls of film at the first shop, which is less than the [tex]$190.50[/tex] you would pay at the second shop.
If cosA = 3/5 and A ∈ (0,90), what is sin2A?
Answer:
[tex]\frac{24}{25}[/tex]
Step-by-step explanation:
Given
cosA = [tex]\frac{3}{5}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]
Then the opposite side using Pythagorean triple is 4, thus
sinA = [tex]\frac{4}{5}[/tex]
Using the trigonometric identity
sin2A = 2 sinAcosA, then
sin2A = 2 × [tex]\frac{4}{5}[/tex] × [tex]\frac{3}{5}[/tex]
= [tex]\frac{2(4)(3)}{5(5)}[/tex] = [tex]\frac{24}{25}[/tex]
Answer:
[tex]\sin(2A)=\frac{24}{25}[/tex]
Step-by-step explanation:
Double angle identity for sine is
[tex]\sin(2A)=2\sin(A)\cos(A)[/tex].
We know [tex]\cos(A)[/tex]. We now need to find [tex]\sin(A)[/tex] to find our answer.
Recall the following [tex]Pythagorean Identity[/tex]:
[tex]\sin^2(A)+\cos^2(A)=1[/tex].
Replace [tex]\cos(A)[/tex] with [tex]\frac{3}{5}[/tex]:
[tex]\sin^2(A)+(\frac{3}{5})^2=1[/tex]
[tex]\sin^2(A)+\frac{9}{25}=1[/tex]
Subtract [tex]\frac{9}{25}[/tex] on both sides:
[tex]\sin^2(A)=1-\frac{9}{25}[/tex]
[tex]\sin^2(A)=\frac{25}{25}-\frac{9}{25}[/tex]
[tex]\sin^2(A)=\frac{25-9}{25}[/tex]
[tex]\sin^2(A)=\frac{16}{25}[/tex]
Now to finally get the value of [tex]\sin(A)[/tex] take the square of both sides:
[tex]\sin(A)=\pm \sqrt{\frac{16}{25}}[/tex]
Since [tex]A[/tex] is in the interval [tex](0,90)[/tex], then [tex]\sin(A)>0[/tex].
[tex]\sin(A)=\sqrt{\frac{16}{25}}[/tex]
[tex]\sin(A)=\frac{\sqrt{16}}{\sqrt{25}}[/tex]
[tex]\sin(A)=\frac{4}{5}[/tex]
So let's finally find the numerical value of [tex]\sin(2A)[/tex].
[tex]\sin(2A)=2\sin(A)\cos(A)[/tex]
[tex]\sin(2A)=2\cdot \frac{4}{5} \cdot \frac{3}{5}[/tex]
[tex]\sin(2A)=\frac{2(4)(3)}{5(5)}[/tex]
[tex]\sin(2A)=\frac{24}{25}[/tex]
Side note:
If [tex]A[/tex] is between 0 and 90 degrees, then we are in the first quadrant.
If we are in the first quadrant, both [tex]x=\cos(A)[/tex] and [tex]y=\sin(A)[/tex] are positive.

When an area is divided into multiple smaller regions ( smaller squares ) is called parts.
In case of Squares, it can be divided into either rows or columns, sometimes both.
Form the given diagram, the square consists of 10 rows and 10 columns which makes 100 (10×10) parts in it.
One fraction is obtained by dividing it by the total number of parts.
In this square, 21 shaded fractions are given.
∴ The fraction of shaded Area = 21/100.
Decimal of shaded Area=0.21.
Jane is adding 3 1/4 + 2 7/8 using fraction strips.How can she rename the sum of the fraction parts of the problem? Explain your thinking
Answer:
3 1/4 + 2 7/8= 6 1/8
Step-by-step explanation:
1. Cross multiply 1/4 and 7/8 which equals 1 1/8.
2. 3+2+1(from cross multiplying)= 6
Answer: 6 1/8
Using fraction strips, the result of 3 1/4 + 2 7/8 is 6 1/8.
What is simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given, Jane is adding 3 1/4 + 2 7/8 using fraction strips.
Fraction strips are rectangular pieces (electronic or copied on paper strips) to represent different parts of the same whole. They can be cut apart and manipulated to see how various parts can be added together to make the whole or compare different fractional amounts for equivalency.
First, we will add fraction parts
=> 1/4 + 7 / 8
We can write 1/4 as 2/8 since they have the same values
=> 2/8 + 7/8
Since now the denominators are the same, therefore we can add the numerators directly. Hence, the sum of 2/8 and 7/8
=> 9/8
=> 8/8 +1/8
=> 1 + 1/8
Thus the sum = 3 + 2 + 1 + 1/8
Sum = 6 + 1/8
therefore, the sum of 3 1/4 + 2 7/8 using fraction strips is 6 1/8.
