Answer:
X= -12
Step-by-step explanation:
-2x-4=20
-2x-4+4=20+4
-2x=24
x=-12
Let's take radius of the basket ball as b
l<span>et's take radius of the tennis ball as t
b = 3.6 t
</span>volume of the basket <span>ball vb = 4/3 pi b^3
</span>volume of the tennis <span>ball vt = 4/3 pi t^3
</span>
therefore
vb / vt = b^3 / t^3
= (3.6t)^3 / <span>t^3
= 3.6^3
= 46.656
so the volume of the basketball is 46.656 times greater than the volume of the tennis ball.</span>

Answer:
The function is equal to 
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to

where
a is a coefficient
(h,k) is the vertex
In this problem we have
(h,k)=(8,-1)
substitute

<u><em>Find the value of a</em></u>
Remember that we have the y-intercept
The y-intercept is the point (0,-17)
substitute
x=0,y=-17






therefore
The function is equal to
