The axis of symmetry is 1.
To find this, do -b/2a, putting -8 in the place of b and -4 in the place of a. Proceed to solve to get 1.
The equation provided is vertex form, so to find the needed components, you need to solve for the vertex. To do so, implement 1 in as x and solve for the vertex.
The vertex is 1, -16.
(y - 16) = -4(x - 1)^2
Although it is not exactly vertex form, the only difference is that instead of it being +k at the end, it is subtracted with the y.
Hope this helps!

Answer:
Withdrawing is negative. A negative divided by a positive is negative
Step-by-step explanation:
Answer:
Both angles B and C are equal to 40°
Step-by-step explanation:
The diagram tells you that the triangle is an isosceles triangle. From this we know that angles B and C will be equal to each other. To find what the angle measures are, we are going to set the two given expressions equal to each other, solve for x, and the plug x back in to get the two angle measures.

Now we are going to plug x back into each expression to solve for angles B and C.
Angle B
⇒ 
Angle C
⇒ 
Both angles B and C are equal to 40°
