Answer:
The solutions are -3 and -1
Step-by-step explanation:
∵ y = -x² - 2x + 8
∵ y = 2x + 11
∴ -x² - 2x + 8 = 2x + 11
∴ -x² - 2x - 2x + 8 - 11 = 0
∴ -x² - 4x - 3 = 0 ⇒ divide both sides by -1
∴ x² + 4x + 3 = 0
∴ (x + 3)(x + 1) = 0
∴ x + 3 = 0 ⇒ x = -3
∴ x + 1 = 0 ⇒ x = -1
∴ The solutions are -3 and -1
The answer would be C, 15
I think it would take an average of both the numbers so first find the average of 60 and 90 by adding and dividing by two. You will get 75 seconds. That is the answer
Your profit is less than the cost of production. Thus, you actually lost 14 dollars. Your profits = -14
