Answer:
average rate of change = 30
Step-by-step explanation:
the average rate of change of f
(
x)
over an
interval between 2 points is the slope of the secant
line connecting the 2 points
It is calculated as
f
(
b
)
−
f
(
a
)
b
−
a
where a, b is the closed interval
[
a
,
b
]
here
[
a
,
b
]
=
[

]
f
(

)
=
f
(

)
=

No. One part of the definition of a prime number is that it's positive.
Answer:
First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).
Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).
