Answer:
C
Step-by-step explanation:
On edge
You’re answer would be $28,000
<span>Website 1 : y = 1.50x + 30
website 2 : y = 2x + 0
y = 4x - 4
y = -4x + 4
4x - 4 = -4x + 4
4x + 4x = 4 + 4
8x = 8
x = 1
y = 4x - 4
y = 4(1) - 4
y = 4 - 4
y = 0</span>
Answer:
This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.
Step-by-step explanation:
Given
Time ------ 0 ----- 2 ------- 4 ----- 6 -----8.
Cost ------- 0 ----- 10 ----- 20 ----30 ----40
Required
Explain why or why not it is a direct variation?
First, we calculate the slope of the table.

Where:


So:




Next, we determine the equation using




<em>The above shows a direct variation with 5 as its constant of proportionality of variation.</em>
Answer:
x=-p+q+y
Step-by-step explanation:
-x=p-q-y
x=-p+q+y
