Answer:
We can write:
x + y = -2
xy = -80
We can rewrite the first equation as x = -y - 2 and then plug that into the second equation to get (-y-2) * y = -80 → -y² - 2y = -80 → y² + 2y - 80 = 0 → (y - 8)(y + 10) = 0 → y = 8, -10. Substituting these values into the first equation we get x = -10, 8 so the answer is (x₁, y₁) = (-10, 8) or (x₂, y₂) = (8, -10).
A. For each dollar the price increases, demand decreases by 450 units.
1= a car tire
2= <span>A reflection would map your right shoe on your left shoe because your right shoe is a mirror image of your left shoe. </span>
I'm just guessing but if you subtract the 1 from 11 and divide by 2 on both sides then T would equal 5
