Write an expression to model the phrase: Myles has $635 nd is earning $120 each
week as a lifeguard.

Step-by-step explanation:

Alright!

we are expected to model the total amount of money Myles have\

firstly he has with him $635

and he is earning $120 weekly

Say the number of weeks he worked is given is n

and let the amount of money Myles will have after n weeks be y

hence we can now model the equation to represent how much Myles will have after n weeks

The expression is same as the equation for a straight line

i.e

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
