Answer:
x intercept is 
y intercept is 
Step-by-step explanation:
1.) turn the equation into slope intercept form, so...
When
then... 
2.)When finding the x-intercept, then plug y=0 and solve for x.

3.) When finding the y-intercept, plug x=0 and solve for x.


Step-by-step explanation:
Here
BC=P=10
AC=B=b
AB=H=15
then using fourmula
h^2= p^2+ b^2
b^2= 15×15 - 10× 10
b^2= 125
b=11.2
Answer:
(Can't tell if it's 3/4 plus -7/8 or you need the answer to both so I'll put both of them) 3/4 is .75 -7/8 is -.875. 3/4 + -7/8 is -1/8 which is -.125
The first choice is substitution because G s being substituted by C
