Answer:
34
Step-by-step explanation:
All angles of a triangle add up to 180 degrees so you would subtract from 180 with the angles you already have to get your answer. 180 - 115 - 31 = B which is 34.
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:
x = 10
Step-by-step explanation:
To find x, you divide 40 by 4. 40 divided by 4 equals 10. So, x equals 10. Hope this helped!
To find the tax, you multiply the tax rate by the amount to be taxed, so...350 × 7%
350 × .07 = $24.50
This is the amount of tax. Now add it to the original price for the total cost.
$350.00 + $24.50 =
$374.50
