(a) If we let x be the number of miles and y be the total cost, the equation for relating the number of miles and the total cost would be,
y = 0.4x + 48
(b) If the rental cost is 60,
60 = 0.4x + 48
The value of x from the equation is 30.
(c) You may prepare the table of values by allowing x be any number and then solve for y until we arrive with an answer for y being equal to 60.
3y+21+8y
11y+21 is the answer
Answer:
A (first picture)
Step-by-step explanation:
Based on the picture, the lines are both perpendicular and the red line splits AB into two equal parts (bisects it), so it must represent the perpendicular bisector of AB.

Answer:
7 hours
Step-by-step explanation:
The total amount is the flat fee plus the amount per hour times the number of hours
16 + 8h = 72
Subtract 16 from each side
16+8h-16 = 72 -16
8h = 56
Divide by 8
8h/8 = 56/8
h = 7
7 hours
