The thing that is true about -5 and 5 is the answer is zero.
Answer:
The x-intercept is 
The y-intercept is 
Step-by-step explanation:
Suppose you have a function f:

The x-intercept is the value of x when
.
The x-intercept is the value of y when
.
Solution
We have:


x-intercept
The x-intercept is the value of x when
. So:

*(-1)




The x-intercept is 
y-intercept
The y-intercept is the value of y when
. So:





The y-intercept is 
For #16, it can be assume that the two angles are linear, so set them both equal to 90 (9x+x-10=90) and solve for x. Once you have x, plug it into the equations to find the measure of both angles. If both your final answers are added, they should equal 180. If not, go back and try to find where you messed up.
