Answer:
{-1,2,3,4}
Step-by-step explanation:
The domain is the input values
(3,7),(4,1),(-1,-8),(2,2),(4,-1)
(3,4,-1,2,4)
We do not list the repeats
(3,4,-1,2)
(-1,2,3,4)
We know the yint, so lets find the slope. (0,-12) and (8,-2) -2--12/8-0 or 10/8 or 1.25
So, the slope is 1.25
The answer is y=1.25x-12
Answer:757.02
Step-by-step explanation:
As y varies directly with x, there is a proportionality constant. As x increases by that certain constant, y also increases. We equate:
y = kx
where k = proportionality constant.
Given the condition, y = 5 when x = 4, then we solve for k:
5 = k(4)
k = 5/4 or 1.25
When y = 8, then
8 = (5/4)(x)
x = 8/(5/4) = (8)(4/5) = 32/5 or 6.4 (ANSWER)
