Insert y in the second equation and solve for x:
4x+(x^2-8)=-8
4x+x^2-8=-8
4x+x^2=0
x^2+4x=0
x = -4
Now you insers this x-value in the first or second equation (i use the first):
y=(-4)^2-8=16-8=8
Therefore the conclusion must be x=-4 and y=8
Answer:
Y intercept is x=0 so y=Mx+b your b is the y intercept

Answer:
84%
Step-by-step explanation:
The area of the large rectangle is 10 × 5 = 50.
The area of the small rectangle is 4 × 2 = 8.
The area of the large rectangle that isn't shaded is 50 − 8 = 42.
The fraction of the large rectangle that isn't shaded is 42 / 50 = 0.84.
Therefore, there is a 84% probability that a point chosen inside the large rectangle is not in the shaded region.
