One approach is to isolate y in the bottom formula, then fill it in to the top one:
x-y=-3 => y = 3+x
so substitute 3+x for y in the top formula (watch the signs) and simplify
x² - 3 - x = 3 => x² -x -6 = 0 => (x+2)(x-3)=0
so x=-2 or x=3.
for x=-2, y=1
for x=3, y=6
These are the solutions.
Answer:
18 degrees heres youre answer!
Step-by-step explanation:
If Angle 1 is x, and Angle 2 is 9x (because one angle is 9 times as large as the other), then x + 9x = 180. Add like terms: 10x = 180. solve for x by dividing both sides by 10. Therefore, x = 18 degrees = smaller angle.

Answer:
g(3) = 11.
Step-by-step explanation:
Given g(x) = x² + 2
Plug '3' into 'x' to solve for g(3):
g(3) = (3)² + 2
g(3) = 9 + 2
g(3) = 11.
