Given f(x) =- 3x + 4, solve for x when f(x) = 1.?

x = 1

Step-by-step explanation:

Remember that "f(x)" is kind of like saying "y." So picture the question like this: solve for x when y = 1. So let's substitute "1" for "y" (or f(x) in this case) like so into the given equation and solve for x:

So, x = 1. Please don't hesitate to ask any questions!

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
