Mia charges $2.25 per hour when she babysits plus $5.00 for transportation expenses. Write a function rule to represent the amount y Mia charges to babysit for x hours. A y = 5.00x + 2.25
B y = 7.25x
C y = 2.25x + 5.00
D x = 5.00y + 2.25

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

ƒ = 0.03b
