3)
f(x) =(x+1)/4
so
f(6a) = (6a+1) / 4
f(6a) =3/2(a) + 1/4

8)
f(x) =(x+1)/4 = 0
x + 1 =0
x = -1

answer
x = -1 makes f(x) = 0

9)
(x+1)/4 >= 10
x + 1 >= 40
x >= 39

Andrei [34K]

Answer:

y=7 number of hours at grocery store

x=18 number of hours at baby- sitting

Step-by-step explanation:

According to the information provided.

x is number of hours at baby- sitting

y is number of hours at grocery store

total number of hours worked

1) x+y =25

total earn in a week

2) x*$6 + y* $9 = $171

from equation 1

x+y=25

x= 25-y

we place the above derived equation in equation 2

x*$6 + y* $9 = $171

(25-y)*$6 + y* $9 = $171

(25*6) -6y +9y =171

150+3y=171

3y=171-150

3y=21

y=7 number of hours at grocery store

x= 25-y

x= 25-7

x=18 number of hours at baby- sitting
