Answer:

x = 11

Step-by-step explanation:

The two angles form a straight line so they add to 180

4x+15 + 11x = 180

Combine like terms

15x+15 = 180

Subtract 15 from each side

15x+15-15 = 180-15

15x = 165

Divide by 15

15x/15 =165/15

x = 11

Write the quadratic function in vertex form. Then identify the vertex.

ddd [48]

Answer:

Step-by-step explanation:

To put the equation into vertex form, we need to complete the square

$g(x) = (x^2 - 4x + ...) - 1\\g(x) = (x^2-4x+(\frac{4}{2})^2 ) - 1 - (\frac{4}{2})^2 \\g(x) = (x-2)^2 - 5\\$

This is in the form

$y = a(x-h)^2 + k\\(h, k)$

So, the vertex is (2, -5)

and $g(x) = (x-2)^2-5$
