Answer:
y=3x-16
Step-by-step explanation:
-3y=-9x+27
y=3x-9
slope: 3
y-2=3(x-6)
y-2=3x-18
y=3x-16
As per the direct variation formula, it take 11 hours : 6 minutes : 36 seconds to earn $25,000 for the restaurant.
Direct variation:
Direct Variation is said to be the relationship between two variables in which one is a constant multiple of the other.
Direct variation equation: y = kx
Given,
A local fast food restaurant takes in $9000 in a 4 hours period. Write a direct variation equation for the relationship income and number of hours.
Here we need to estimate how many hours it would take the restaurant to earn $25,000.
a) Let us consider income (I) directly varies to number of hours (h) where k is the constant of variation.
I = kh ⇒ Direct variation equation
Solve for k:
9,000 = (k)(4)
k = 9,000/4
k = 2,250
b) When income (I) = 25,000, find the number of hours:
I = kh
25,000 = (2,250) (h)
h = 25,000/2,250
h = 11.11
It will take approximately 11 hours : 6 minutes : 36 seconds for the restaurant to earn $25,000.

It'd be 2 I think but I'm not good at math
Answer:
U (2,-1)
Step-by-step explanation:
if you replace x to 2, your answer will come out to be -1
The answer i came up with is 0.68 i don't know if thats what you need or not. hopefully i helped.
