Answer:
$150
Step-by-step explanation:
Find how much Nicole earns for 3 hours by plugging in 3 as h in the function:
E(h) = 50h
E(3) = 50(3)
E(3) = 150
So, for tutoring for 3 hours, Nicole will earn $150
Your answer is true.

The equation is used to find the equation of a line in slope-intercept form.
m is used to represent the slope.
x is used to represent the x-axis.
y is used to represent the y-axis.
b is used to represent the y-intercept.

T= 7M+MFG
SUBTRACT 7M from both sides
T- 7M = MFG
DIVIDE BOTH SIDES BY MF
T-7M / MF = G
2 hr 15 min = 2

hours = 2.25 hours
"how far" means distance ... so distance = rate x time
distance = 56 x 2.25 =
126 miles
"how long" means time ... so using the same formula
168 = 56 x time
divide both sides of the equation by 56 to solve
3 hours = time
