The function y=53x is shifted up 4 units. What is the equation of the new function?

the correct answer is 45x

9×5=45 then add the x

y=mx+b

step-by-step explanation:

m slope, b y-intercept

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

8
