So to find the speed we find the unit rate
to do that we do (y2-y1)/(x2-x1)

so we can use any points, but I'm going to use points (0,25) and (1,75)

75-25=50
2-1=1
then we do rise(y) over run(x)
50/1=50

so the boat is going 50mph making your answer. D

tatiyna

<em>Missing:</em>

<em>If Hector earned $126 last week, what was the amount of Hector's raise per hour?</em>

Answer:

x = 2.5

Step-by-step explanation:

Given

y=12(8+x)

Required

Solve for x when y = 126

y=12(8+x)

126 = 12(8 + x)

Divide through by 12

\frac{126}{12} = \frac{12(8 + x)}{12}

10.5 = 8 + x

x = 10.5 - 8

x = 2.5
