If the triangle has a right angle, the measure of the third side is 12.8 inches
It can be both because there are diffrent sizes
The y-intercept is (0, -8)
if you set the equation to slope intercept format you get
y=-2x-8
So you have x, then you square it to get x^2, then you minus 2x, then +3
The inverse is going backwards so you -3 then +2x then square root x
So you get square root x + 2x -3
I'm pretty sure this is right, sorry if I'm wrong.
-3 = x/-9
To make this easier, I'll put it in normal numbers
(-3 = x/-9) -1
3 = x/9
Multiply both sides by nine to take out the division.
27 = x
Hope that this helped!
