Answer:
y - 8 = -2(x + 1)^2
Step-by-step explanation:
The vertex of this parabola is (-1, 8). It opens downward, so the x^2 term has a negative coefficient. The zeros are (-3, 0) and (1, 0), and the y-intercept is (0, 7).
Through the vertex form of the equation of a parabola we get:
y - (8) = a(x - (-1)) + 7, or
y - 8 = a(x + 1)^2. Find coefficient a by substituting the coordinates (-3, 0) in this equation:
0 - 8 = a(-3 + 1)^2, or
-8 = a(-2)^2, or a = -2
The desired equation is
y - 8 = -2(x + 1)^2
Say you want to figure up how much 2 pizzas would cost if they’re 15 dollars apiece, 15•2
Answer: 4
Step-by-step explanation: 3m=m+8. Subtract m from both sides to get 2m=8. Divide both sides by 2 to get m=4
I believe 2 is the answer because it is an exact replica of abc
