A Question 4(Multiple Choice Worth 4 points)
(03.04 LC)
Greg made pudding every weekend. The more times he made pudding, the more practice he gained. The time he took to
make the same amount of pudding every week decreased with practice. The function below shows the number of hours f(x)
Greg took to make pudding after he had made it x times:
f(x) = 2(0.8)
Which graph best represents the function?

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

b

step-by-step explanation:

multiply terms on numerator/ denominator by (x - 1)

= ← distribute numerator/ denominator

= ← simplify

=

= → b
