Answer:
b - 9 = 2 I believe would be it
90÷5=18 which means she makes $18 every hour.
Answer= $18
Answer:
y=-3x+5
Step-by-step explanation:
concepts: y=mx+b is slope intercept equation formula
m=slope
b= y intercept
Therefore we need to find the slope and y intercept
first find slope
m=
let y2 be 2
let y1 be -4
let x2 be 1
let x1 be 3

6/-2 = -3
m=-3
slope is -3
y= -3x+ b
we need find y intercept now
just plug in (1,2) into that equation
2=-3(1)+b
b=5
y=-3x+5
Answer:
3
Step-by-step explanation:
Given
f(x) =
, then
f(12) =
=
= ± 3
There are 2 values 3 and - 3
The positive value of f(12) is + 3
