The unit rate at which Martin paints in walls per gallon is 1 7/25 walls per gallon
<h3>Unit rate</h3>
Unit rate of paint per gallon = Quantity of wall / gallon of paint
= 4/5 ÷ 5/8
= 4/5 × 8/5
= (4 × 8) / (5 × 5)
= 32/25
= 1 7/25 walls per gallon

Problem 1
Answer: Direct variation; k = 1/4
----------------------
Explanation:
We can rewrite the given equation y = x/4 into y = (1/4)x. Then note how it's in the form y = kx. In this case, k = 1/4. In decimal form, this is k = 0.25
All direct variation equations are in the form y = kx. The value of k is the constant of variation.
====================================================
Problem 2
Answer: Inverse variation; k = 9
----------------------
Explanation:
The equation 9/y = x rearranges to xy = 9.
We can then solve for y to get y = 9/x
This is in the form y = k/x, where k = 9
All inverse variation equations are in the form y = k/x, with k as the constant of variation.
Answer:
Terms:
1) = 7/3
2) = -7/9
3) = 7/27
4) = -7/81
Step-by-step explanation:
Your question did not state the equation of f(x), however; assuming f(x) = 7/(1+x) ,....... at a = 2
see solution attached then use it to work your f(x)
