Answer:
Step-by-step explanation:
So if y=308x then we have to use the substitution method.
y=308x
y=122x+2338
so y=308x=122x+2338
308x-122x=186x
186x=2338
do the division and thats your answer. which is what y equals
Answer:
1.9

Step 1:
Cost * Markup= $ Markup
=$20 * 15%
=20 * 0.15
=$3.00 markup
Step 2:
Cost + $ Markup= Selling Price
$20 + $3 = $23.00
Selling Price= $23.00
Hope this helped :)
The equation 
has two variables, y (longevity of car engine) and x (number of times oil changed).
This falls into the slope-intercept form of a linear function,which is 
, where b is the y-intercept (or in other words, the value of y when x is 0).
Comparing our equation to the slope-intercept form of a linear function tells us that the value 0.1576 is the y-intercept.
<em>It means </em><em>0.1576</em><em> is the expected longevity of a car engine when x is 0 (number of oil changed is 0). </em>This is answer choice A.
ANSWER: A
