An electrician earns $110 after his first hour of working for a client. His total pay based on the number of hours worked can be
VLD [36.1K]
I don't like trying all of them so I will make up my own which will probably be in the answers 
so equation is
f(x)=pay
x=hours worked
solve so 
f(1)=110
f(2)=130
f(3)=150
f(4)=170

they seem to be increasing in 20 increments so therefor the pay is linked to hours times 20 so that measn that every hour he works, he gets 20 dollars
therefor the answer is f(n+1)=f(n)+20 since we know that 1 hour=$20 so n+1hour=n+$20

the answe ris f(n+1)=f(n)+20

What is the solution set of (x - 2)(x - 3) = 2?
Deffense [45]

Answer:

X = 4, 1

Step-by-step explanation:

Multiplying out

X^2 - 2x - 3x +6 = 2

X^2 - 5x +4 = 0

Factoring:

X^2 - 4x - X +4

X(x-4) - 1(x-4)

(x-1)(x-4)=0

X= 1, 4
