-b +or- root (b^2 -4ac) / 2a
3+or- root 9+20/ 2
3+ or - root 29 /2
5.38516480713 + 3 = 8.385 / 2
x = 4.1925
or x = -1.1925
a=1
b=-3
c=-5

It's a ball, so a sphere.
V=4/3πr^3(That's the sphere formula)
V=128.
128=4/3πr^3
3.13 is your approximate radius.
r= (3* 128/4π)
Answer:
(9,36)
Step-by-step explanation:
Substitute the 4x for the y in second equation.
Basically setting them equal to each other because the both have 'y='
4x = 8x - 36
-4x = -36 (subtract 8x from both sides)
x = 9 (divide by -4, both sides)
y = 4(9) (Substitute the x value into first equation)
y = 36
