Answer:
<h3>x by y </h3>
Step-by-step explanation:
Set up a proprtion and cross multiply.
18/7.5=22/4x+1
7.5×22=18 (4x+1)
165=72x+18
147=72x
x=2.04
Answer:
5
Step-by-step explanation:
The Y intercept is where the line crosses the Y axis when X = 0.
(X,Y) -> (0, 5)
The equation of that line looks to be Y = X + 5.
That equation I wrote follows the Y = mx + B format.
The +B is the Y intercept.
"zeros" are solutions for x that make the equation equal to zero.
(x - 8)(x + 8)(x - 1) = 0
