Hi student, let me help you out! :)

We are asked to find the solution to the inequality:

$\star~\large\pmb{\cfrac{x}{9}+3 < 4}$

$\triangle~\fbox{\bf{KEY:}}$

First, subtract 3 from both sides, then multiply both sides by the denominator.

Step 1.

$\star~\large\pmb{\cfrac{x}{9} < 4-3}$

$\star~\large\pmb{\cfrac{x}{9} < 1}$

Step 2.

$\star~\large\pmb{\cfrac{x}{9}\times9 < 1\times9}$

Notice that on the left, the 9s cancel, and we're left with x.

Step 3.

$\star~\large\pmb{x < 9}$

This is the solution.

Hope it helps you out! :D

Which function below has the lowest y intercept?

neonofarm [45]

Our first function is g(x). Al had two dozen donuts means that two dozen is the y-intercept of this function. A dozen equals 12, therefore two dozens is 24. Every cubicle he passed, he lost 2 donuts is the slope of the function and it is negative, that is -2, thus:

$g(x)=-2x+24 \\ \\ \boxed{y-intercept = 24}$
