What is the vertex of the function f(x) = x2 + 12x?
1 answer:
We can start by figuring out the axis of symmetry. y = x² + 12x = x (x + 12) So roots are x = -12 or 0 Therefore axis of symmetry is x = (-12 + 0) / 2 = -6 We got x-coordinate of vertex. Now plug in x=-6 to solve for y. y = (-6)² + 12(-6) = 36 - 72 = -36 Therefore vertex is (-6, -36) .

Answer:
6ft tall
Step-by-step explanation:
Given we know that the scale is 1 in 2ft.
Using this information we know we could divide 12/2=6. We also know that we could multiply 2×6=12. Therefore, we know that the model plane is 6ft tall.

Answer: 7.0 (choice E) </h3>
=============================================
Work Shown:
Let m = 2 so we can use this result later.
Let n = 5 so we can use this result later.
Add the two results.
m+n = 2 + 5 = 7.0 is the final answer.
