graph the line y=3/4x-2
Answers
Step-by-step explanation: First, notice that this line is in slope intercept or more commonly known as y = mx + b form because y is by itself on one side of the equation.
Our slope or m therefore is the coefficient of the x-term which in this case is 3/4. Our b or y-intercept is the constant term which in this case is -2.
To graph a line given the slope and y-intercept, we will first start with its y-intercept. The y-intercept of a line is the point where the line crosses the y-axis. Since our y-intercept is -2, we start by plotting the point that is down 2 units on the y-axis and we call that point A.
From there we take our slope of 3/4 so our rise is 3 and our run is 4 and we end up at point B. Now we can connect the two points and we have our line.

The weight of an object on a particular scale is 145.2 lbs. The measured weight may vary from the actual weight by at most 0.3 lbs. What is the range of actual weights of the object?
Answers
145.2+0.3=145.5
The range is 144.9-145.5
Answer:
[tex]144.9\leq x\leq 145.5[/tex]
Step-by-step explanation:
Let x represent actual weight of object.
We have been that the weight of an object on a particular scale is 145.2 lbs. The measured weight may vary from the actual weight by at most 0.3 lbs.
[tex]|\text{Actual}-\text{Ideal}|\leq \text{Tolerance}[/tex].
Upon substituting our given values, we will get:
[tex]|x-145.2|\leq 0.3[/tex]
Applying absolute value rule [tex]|u|\leq a=-a\leq u\leq a[/tex], we will get:
[tex]-0.3\leq x-145.2\leq 0.3[/tex]
Add 145.2 on each side:
[tex]-0.3+145.2\leq x-145.2+145.2\leq 0.3+145.2[/tex]
[tex]144.9\leq x\leq 145.5[/tex]
Therefore, our required range will be [tex]144.9\leq x\leq 145.5[/tex].
what is the sum of this infinite geometric series? 2+ 2/5+2/25+2/125+..... ...?
Answers
Final answer:
The sum of the infinite geometric series 2 + 2/5 + 2/25 + 2/125 + ... is 2.5, determined by using the formula for the sum of a convergent geometric series, which in this case is S = 2 / (1 - 1/5).
Explanation:
The question you've asked relates to the sum of an infinite geometric series. The series given is 2 + 2/5 + 2/25 + 2/125 + ..., which is a series where each term after the first is found by multiplying the previous term by 1/5. To find the sum of this infinite geometric series, we can use the formula for the sum of a convergent geometric series, which is S = a / (1 - r), where 'S' is the sum of the series, 'a' is the first term, and 'r' is the common ratio (the factor we multiply by to get each term in the series).
In this case, the first term 'a' is 2, and the common ratio 'r' is 1/5. So our formula becomes S = 2 / (1 - 1/5), which simplifies to S = 2 / (4/5) or S = 2 * (5/4), which gives us S = 2.5. Therefore, the sum of the infinite geometric series is 2.5.

find the amount that results from each. $50 invested at 6% compounded monthly after a period of 3 years ...?
Answers
Final answer:
Using the compound interest formula, the total amount after three years for $50 invested at 6% compounded monthly is approximately $59.70.
Explanation:
To calculate the future value of $50 invested at 6% compounded monthly after a period of three years, we use the formula for compound interest:
FV = P × (1 + (r/n))³⁼ ×⁴
where:
FV is the future value of the investment,
P is the principal amount ($50),
r is the annual nominal interest rate (6% or 0.06),
n is the number of times the interest is compounded per year (12, for monthly compounding),
t is the time the money is invested for, in years (3 years).
Using these values, we calculate as follows:
FV = $50 × (1 + (0.06/12))³·×´ = $50 × (1 + 0.005)·¹·´
Now we calculate this raised to the power of 36 (3 years times 12 months):
FV = $50 × (1.005)³···¶ = $50 × 1.194052
Thus, FV ≈ $59.70
The total amount after three years would be approximately $59.70, assuming the interest is compounded monthly at a rate of 6%.

The weight of Stephen's dog such that Stephen has a dog that weighs 5 times as much as Ian's dog will be 60 pounds.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Let's assume the weight of Stephen's dog is "s" while Ion's dog is "i".
As per the given,
Stephen has a dog that weighs 5 times as much as Ian's dog.
s = 5i
Total weight, s + i = 72
Substitute, i = 72 - s into s = 5i
s = 5(72 - s)
s = 360 - 5s
s + 5s = 360
6s = 360
s = 60 pounds.

What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

There are total of 84 students in the robotics club and the science club. The science club has 12 more students than the robotics club. How many students are in the science club?
Answers
Robotics Club = x
Science Club = (x + 12)
Total = 84
Okay, so here's the equation:
x + (x + 12) = 84 ~ Add like terms.
2x + 12 = 84 ~ Subtract 12 by both sides.
2x = 72 ~ Divide both sides by 2.
x = 36 ~ Meaning that the Robotics Club has 36 members.
At this point you can do: 84 - 36 = 48 which gives you the number of members in the Science Club, though...:
36 + (36 + 12) = 84 ~ Add the two in the parenthesis to get your answer.
36 + 48 = 84 ~ 48 is the number of Students in the Science Club.
84 = 84
In conclusion: The Science Club has 48 students.
Hope that helps. ^ ^
{-Ghostgate-}
By setting up an equation and solving for the number of students in each club, we find there are 48 students in the science club.
To solve the problem, we can set up an equation based on the information given. Let the number of students in the robotics club be represented by x.
According to the problem, the science club has 12 more students than the robotics club, so the science club has x + 12 students. We also know that there are a total of 84 students in both clubs combined. Therefore, we can set up the following equation:
x + (x + 12) = 84
Combining like terms, we have:
2x + 12 = 84
Subtracting 12 from both sides gives us:
2x = 72
Dividing both sides by 2 gives us:
x = 36
So, there are 36 students in the robotics club. To find the number of students in the science club, we add 12 to the number of students in the robotics club:
36 + 12 = 48
Therefore, there are 48 students in the science club.
Sheila is ordering pizzas for a party. each plain pizza costs $9.00, and each topping costs $1.50. the delivery charge is $3.00. write a function rule to show the total cost of the pizzas if the pizza ordered has 2 toppings. how much will 5 pizzas cost?
Answers
f (5) = $12.00 * 5 + $3.00
f (5) = $63.00
Answer: [tex]c=12x+3[/tex], where c is the total cost of x pizzas.
The cost of 5 pizzas = $63
Step-by-step explanation:
Given : Cost of each pizza = $9.00
Cost of each topping = $1.50
⇒ Cost of 2 toppings = 2 x $1.50 = $3.00
Then, the cost of each pizza having 2 toppings = $9.00+ $3.00= $12.00
Let x be the number of pizzas .
Then , the cost of x pizzas = 12x
Since , Delivery charge = $3.00
Then, the total cost of ordering x pizzas( in dollars) = Cost of x pizzas+ Delivery charge = 12x+3
Function rule to show the total cost of the pizzas if the pizza ordered has 2 toppings : [tex]c=12x+3[/tex] , where c is the total cost.
Put x= 5
[tex]c=12(5)+3=60+3=63[/tex]
Hence, the cost of 5 pizzas = $63
