Answer:
Step-by-step explanation:
video store A : 15 + 1.75m
video store B : 7.5 + 2.25m
15 + 1.75m = 7.5 + 2.25m
15 - 7.5 = 2.25m - 1.75m
7.5 = 0.50m
7.5 / 0.50 = m
15 = m <=== there would have to be 15 movie rentals to make them equal
check...
15 + 1.75m 7.50 + 2.25m
15 + 1.75(15) = 7.50 + 2.25(15) =
41.25 41.25
yep...it checks out
y = 9x + 8
y = 7.5x + 16
1.5x = 8
x = 5.3 hours
-3
the c value transforms the function up and down the y axis. so if you want a graph 9 units above -12, it is -12+9, which is -3.
the r means remainder
there ya go:)
x+13=3x-2. the answer for x is 7.5
