Answer:
<h2> 2.32dollar/mile</h2>
Step-by-step explanation:
step one:
Given the function
y = 14 +2.31x + 4.50
we can solve for the rate of change by applying differentiation.
step two:
differentiating y which is cost with respect to x which is the miles
dy/dx= 0+2.32+0
dy/dx=2.32
Hence the rate of change of cost in the dollar to a mile is
2.32dollar/mile
Answer:
slope=2/3
Step-by-step explanation:
form is y=mx+b where m is the slope.
Answer:
2x - y = 9
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Rearrange y + 1 = 2(x - 4) into this form
y + 1 = 2x - 8 ( add 8 to both sides )
y + 9 = 2x ( subtract y from both sides )
9 = 2x - y ⇒ 2x - y = 9 ← in standard form
