Answer 1

Answer:

The complete question is:

At the gas station, each liter of gas costs $3dollar but there's a promotion that for every beverage you purchase you save $0.20 dollar on gas. Is your total savings on gas proportional to the number of beverages you purchase?

Answer:

Yes, your total savings on gas is proportional to the number of beverages you purchase.

Explanation:

What is a proportional relationship?

A proportional relationship, also known as direct relation, between two variables exists when the ratio between every pair of data is constant.

In this case the variables are:

number of beverage purchased

savings

Thus, as per every beverage purchase you save $ 0.20 the ratio of total savings to the number of beverage purchases is:

savings / beverages purchase = $ 0.20 / beverage

That means that you can determine the savings by multipliying the number of beverages times $ 0.20.

For proportional relationships it is easy to build a table that shows the behavior of the variables. This shows you that:

Number of beverages savings ratio

1 $ 0.20 $0.20 / 1 beverage = 0.20

2 $ 0.40 $0.40 / 2 beverages = 0.20

3 $ 0.60 $0.60 / 3 beverages = 0.20

4 $ 0.80 $0.80 / 4 beverages = 0.20

Consider the function f(x)=6x+5
(A) find it’s average rate of change by changing x=1 to x=5

Answers

Answer: I really don’t know

Step-by-step explanation: I need help with this as well. I’m really sorry if you were looking for a real answer

Final answer:

The average rate of change of the function f(x) = 6x +5 over the interval x = 1 to x = 5 is calculated with the formula Δf/Δx and is found to be 6.

Explanation:

In the given function, f(x) = 6x + 5, the average rate of change is calculated by the formula Δf/Δx, which refers to the change in the function value over the change in the x-value. Plugging in the given values, we have:

Δf = f(5) - f(1) = [6(5) + 5] - [6(1) + 5]

Δx = 5 - 1

So, the average rate of change is Δf/Δx = [30 + 5 - 6 - 5]/(5 - 1) = 24/4 = 6.

Write the equation of the function g(x) if g(x) = f(x+2) +4 and f(x) = x^3 -7

Answers

f(x) = x³ - 7
f(x + 2) = (x + 2)³ - 7
f(x + 2) = (x + 2)(x + 2)(x + 2) - 7
f(x + 2) = (x(x + 2) + 2(x + 2))(x + 2) - 7
f(x + 2) = (x(x) + x(2) + 2(x) + 2(2))(x + 2) - 7
f(x + 2) = (x² + 2x + 2x + 4)(x + 2) - 7
f(x + 2) = (x² + 4x + 4)(x + 2) - 7
f(x + 2) = (x²(x + 2) + 4x(x + 2) + 4(x + 2)) - 7
f(x + 2) = (x²(x) + x²(2) + 4x(x) + 4x(2) + 4(x) + 4(2)) - 7
f(x + 2) = (x³ + 2x² + 4x² + 8x + 4x + 8) - 7
f(x + 2) = (x³ + 6x² + 12x + 8) - 7
f(x + 2) = x³ + 6x² + 12x + 8 - 7
f(x + 2) = x³ + 6x² + 12x + 1

g(x) = f(x + 2) + 4
g(x) = (x³ + 6x² + 12x + 1) + 4
g(x) = x³ + 6x² + 12x + 1 + 4
g(x) = x³ + 6x² + 12x + 5
