ur welcome plz mark brainliest
Rewrite the first function so that the two functions are in standard form:
y - 3 = -2x - 8 => y = 3 - 2x - 8 => y = -2x - 5
and
y= -2x - 5
We can now see immediately that these two functions have the same slope (-2) and same y-intercept (providing that you meant "y = -2x - 5).
The graphs of these 2 functions are identical.
Answer:8
Step-by-step explanation:
X+56=x^2
X^2-x-56=0
X^2-8x+7x-56=0
X(x-8)+7(x-8)=0
(X+7)(x-8)=0
X+7=0 or x-8=0
X=-7 or x=8
