Answers

You just need to add the two equations so (-4x+3)+(3x^2 +2x-4)
You end up with c. 3x^2-2x-1

Answer:

Correct option is:

C. (f + g)(x) = 3x² – 2x – 1

Step-by-step explanation:

f(x) = –4x + 3 and g(x) = 3x² + 2x – 4

We have to find (f + g)(x).

We know that (f+g)(x)=f(x)+g(x)

⇒ (f+g)(x)=-4x+3+3x²+2x-4

⇒ (f+g)(x)=3x²-2x-1

Hence, Correct option is:

Algebraic Expressions Question

A company charges $59.99 for cable TV installation and $49.99 per month for basic cable service.

Part A
Write an algebraic expression to represent the total cost of m months of basic cable service, including installation.

Algebraic Expression: ________________

Part B
How much will it cost for installation and one year of basic cable service?

Explain:

Total Cost: ______________

This problem is continued on the next page.

Part C
After the first 12 months, the charge will be increased to $69.95 per month. What is the total cost of installation and basic cable service for the first two years?

Explain:

Answers

Part A.

We can create a linear equation from this problem. Let us say that C is total cost and m is number of months, therefore:

C = 59.99 + 49.99 m

Part B. For m = 12 months, the total cost is:

C = 59.99 + 49.99 * 12

C = $659.87

Part C. We have already calculated in part B the total cost for the 1st year:

C1 = $659.87

For the 2nd year, the equation becomes:

C = 59.99 + 69.95 m

C = 59.99 + 69.95 * 12

C2 = $899.39

Therefore the total cost C1 + C2 is:

$1,559.26

Final answer:

The total cost of m months of basic cable service, including installation, can be represented by the algebraic expression 59.99 + 49.99m. For installation and one year of basic cable service, the cost is 659.87. For the first two years, including installation and basic cable service, the cost is 1549.23.

Explanation:

Part A:

To represent the total cost of m months of basic cable service, including installation, we can use the algebraic expression:

59.99 + 49.99m

Part B:

To calculate the total cost for installation and one year of basic cable service, we substitute 12 for m in the expression:

59.99 + 49.99(12) = 59.99 + 599.88 = 659.87

Part C:

For the first two years, the cost includes the installation and basic cable service for the first 12 months at $49.99 per month, and the following 12 months at $69.95 per month. So we write the expression as:

59.99 + 49.99(12) + 69.95(12) = 709.83 + 839.4 = 1549.23

principal: $450
rate: ?
time: 3 years
interest earned: 67.50
new balance: ?

Answers

Hi there! I can help you.

Rate: To find the rate, let’s divide interest earned by the principal. When you do, you get 0.15. Multiply by 100 to get 15 and divide by 3 to get 5. The simple interest rate is 5%.

New balance: All you have to do is add the principal and he new balance. When you do, you get 517.5. The new balance is $517.50.

To find the missing rate and new balance, we used the simple interest formula. The rate was calculated to be 5% and the new balance after 3 years, including interest earned, was determined to be $517.50.

The subject in question here is simple interest calculation, which is a fundamental concept in finance and mathematic subjects. To solve for the missing rate and new balance, we can use the formula Interest = Principal x rate x time.

Principal: $450Rate: ? (We will solve for this)Time: 3 yearsInterest Earned: $67.50New Balance: ? (We will solve for this too)

First, we rearrange the interest formula to solve for the rate:

Rate = Interest / (Principal x Time)

Plugging in the provided numbers:

Rate = $67.50 / ($450 x 3)

Rate = $67.50 / $1350

Rate = 0.05 or 5%

Now, we find the new balance using the formula:

New Balance = Principal + Interest

New Balance = $450 + $67.50

New Balance = $517.50

Therefore, the interest rate is 5% and the new balance after 3 years is $517.50.

Find the coordinates of the points of intersection of the graphs with coordinate axes: y=−1.5x+3

Answers

Final answer:

The coordinates for the points of intersection of the line y=-1.5x + 3 with the coordinate axes are (0,3) for y-axis and (2,0) for the x-axis.

Explanation:

To find the points of intersection of the line with the coordinate axes, we will set the values of y and x to zero separately. So, let's start from the intersection of the line with the y-axis. For this, we set x=0 in the equation y = -1.5x + 3. Thus, y = 0*(-1.5) + 3 which gives us y = 3. So one point of intersection is (0,3). Next, finding the x-intercept requires setting y=0, which gives 0 = -1.5x + 3. Solving this equation, we get x = 3 / 1.5 or x=2. Hence, the other point of intersection is (2,0). Therefore, the coordinates for the points of intersections are (0,3) and (2,0).

What is an equation of the line that is perpendicular to y + 1 = - 3 (x - 5) and passes through the point (4, -6)?

Answers

y + 6 = 1/3 (x - 4)

Replace the second y (y1) and the 2nd x (x1) with the new points and then -3 become 1/3 due to perpendicular meaning opposite reciprocal (2/3 reciprocal is 3/2 and the opposite would be its negative, -3/2, for example)

So there's your answer plus some info for future knowlege

Final answer:

The equation of the line that is perpendicular to y + 1 = -3 (x - 5) and passes through the point (4, -6) is y = 1/3x - 22/3.

Explanation:

The subject of this question is Mathematics, specifically the topic of linear equations.

The line given in the question is y + 1 = -3 (x - 5). To find the equation of a line that is perpendicular to this given line and passes through the point (4, -6), we need to understand the concept of slope.

The equation of the given line can be rewritten as y = -3x + 15 -1, or y = -3x + 14. The slope of a line perpendicular to this line would be the negative reciprocal of -3, which is 1/3. Then, by using the point-slope form of a line, (y - y1) = m (x - x1), where m is the slope and (x1, y1) is the point through which the line passes (in this case, (4, -6)), we get: y - (-6) = 1/3 (x - 4) or y + 6 = 1/3x - 4/3.

Simplifying, the equation of the perpendicular line is y = 1/3x - 4/3 - 6 or y = 1/3x - 22/3.

To convert 175% to a fraction, write it as 175/100 and then simplify by dividing both numerator and denominator by their greatest common divisor, 25, which gives a simplified fraction of 7/4.

One hundred seventy five percent as a fraction can be converted by writing the value of the percent as a fraction with a denominator of 100. To convert the percent to a fraction, we write 175% as 175/100. This fraction can then be simplified. To simplify, we can divide both the numerator and the denominator by their greatest common divisor, which is 25.

Here is the step-by-step simplification process:

Write 175% as a fraction: 175/100

Divide both the numerator and the denominator by 25: (175 ÷ 25) / (100 ÷ 25) = 7/4

The simplified fraction for 175% is therefore 7/4.

Which absolute value function defines this graph?

The first one because it has a negative slope (which is -4) and h is always the opposite while k stays the same. By the way h is the 2 and k is the 3

Answer:

A. [tex]f(x)=-4|x+2|+3[/tex]

Step-by-step explanation:

We have been given an image of an absolute function. We are asked to find the formula for our given absolute function.

The formula of parent absolute function is [tex]f(x)=|x|[/tex] with vertex at (0,0)

We can see that the vertex of our given function is at [tex](-2,3)[/tex]. This means that our function is shifted to left by 2 units. We can represent this information as: [tex]f(x)=|x--2|=|x+2|[/tex]

We can also see that our graph is reflected across x-axis, so after reflection our function would be [tex]f(x)=-|x+2|[/tex]

We can see that our graph is shifted upwards by 3 units, so graph after shifting would be [tex]f(x)=-|x+2|+3[/tex].

Our graph is stretched vertically by a scale factor of 4, so after stretching our function would be [tex]f(x)=-4|x+2|+3[/tex].

Therefore, option A is the correct choice.

3(2.7+5)−23(2.7+5)−2
Enter your answer in the box.

Answers

Final answer:

The simplified expression is -202.2, which can be expressed as a decimal as -202.2.

Explanation:

To simplify the expression, we need to perform the operations in order of operations (PEMDAS/BODMAS). First, we simplify the expressions inside the parentheses:

2.7 + 5 = 7.7

Next, we can rewrite the expression:

3(7.7) - 23(7.7) - 2

Now, we can multiply each term:

3 * 7.7 = 23.1

23 * 7.7 = 177.1

-23.1 - 177.1 - 2

Finally, we can combine like terms:

-202.2

The simplified expression is -202.2, which can be expressed as a decimal as -202.2.

Final answer:

To simplify the expression 3(2.7+5)−23(2.7+5)−2, we first evaluate the addition inside the parentheses and then perform the multiplication and subtraction step by step to get the final simplified answer as -156.

Explanation:

To simplify the expression 3(2.7+5)−23(2.7+5)−2, we first evaluate the addition inside the parentheses: 2.7+5 = 7.7.

Substituting this value back into the expression, we get 3(7.7) - 23(7.7) - 2.

Next, we perform the multiplication: 3(7.7) = 23.1 and 23(7.7) = 177.1.

Substituting these values back into the expression, we have 23.1 - 177.1 - 2.

Finally, we perform the subtraction: 23.1 - 177.1 = -154 and -154 - 2 = -156.

Therefore, the simplified answer as a decimal is -156.

B. the number of jeans the stock is reduced by from each sale

C. the total amount of jeans in stock after each sale

D. the number of jeans purchased

Answers

I think that it is A. I'm tired and it is two in the morning

Answer:

Remaining amount of jeans after x sales = 688 - 2x

In this expression

2x = The number of jeans purchased.

-2 = The number of jeans the stock is reduced by from each sale.

2 = The number of jeans sold with each purchase.

Step-by-step explanation:

Given information:

Total number of jeans = 688

He decides to reduce the stock by having a buy one get one free sale. It means that every purchase will reduce this inventory by 2 pairs of jeans.

Average rate of change = -2

Let x be the number of purchase.

So, the total amount of jeans in stock after each sale is

Remaining amount of jeans after x sales = 688 - 2x

In this expression

2x = The number of jeans purchased

-2 = The number of jeans the stock is reduced by from each sale.

2 = The number of jeans sold with each purchase

Negative K over five equals seven over five

Answers

Hey! Sorry about your misunderstanding of your work, Allow me to help :)

Let's turn that phrase into an equation.

Negative K ( - k) over five ( /5 ) equals ( = ) seven (7) over five ( /5)

Let's put that together.

- k/5 = 7/5

To solve, we need to get rid of the fraction by getting rid of the denominator, in this case, the denominator for both sides is 5. Multiply each side by 5 to cancel out the 5. We get :

- k = 7

Now we need to get rid of that negative sign next to k, so what we do is divide each side by -1 so we can cancel out that negative 1 next to k.

Our Final answer is k = -7 .

The scatterplot and trend line show a positive correlation between advertising costs and sales. The slope was found using the points (6.4, 117) and (6.6, 120). What is the value of b in the equation of the trend line? y = 15x + b

Answers

When x = 6.4, y=117, therefore
15*6.4 + b = 117
b = 117 - 96 = 21

Confirm this value by checking (6.6, 120).
15*6.6 + 21 = 120 (Correct)

Answer: b = 21

The value of b in the equation of the trend line is 21

The equation of the trend line of the scatter plot is given as:

y = 15x + b

The points are given as: (6.4, 117) and (6.6, 120).

Using (6.4, 117), we have:

117 = 15 * 6.4 + b

Evaluate the products

117 = 96 + b

Subtract 96 from both sides

21 = b

Rewrite as:

b =21

Hence, the value of b in the equation of the trend line is 21
