A car rental service charges a customer $45 a day for a car, $60 a day for a SUV, and $70 a day for a pickup truck. There is also an insurance fee of $27. How much would it cost for someone to rent a SUV for 3 days.
It would cost $207 to rent a SUV for 3 days.
y = (-3/4)x + 2. Solve for y is x is 8.
y = -4
6x + 15 = 3x + 8
x = (-7/3)
(-42 / 7) * -8
48
-3x + 5 < -16
x > 7 or 7 < x
Set up a table with 4 slots and fill it in with 3 pairs of coordinates that are proportional to 2/6.
1/3, 3/9, 4/12, 5/15, 6/18, 7/21, 8/24, 9/27, 10/30...
Convert this equation into slope-intercept form and solve for y if x is 2. 5x - 2y = -16
y = (5/2)x + 8, and 13.
