Write the equation for the graphed function. i worked out y = 5 - 4 (x + 4)^2 but that isn't right. any would be appreciated.

Vertex form for a parabola with vertex (p,q) is

We have (p,q)=(-4,5) and another point (-3,2) so we can solve for a:

Putting it together,

We could multiply that out if we like but I won't bother.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
