It so b I think m if not it would be c
2
3
x5
8
=
1
12
x5
is how its done
The discount off is $10, so the price would be 30 dollars
Y - y₁ = m(x -x₁)
slope m = -2, from point (10, -9) , x₁ = 10, y₁ = -9
y - y₁ = m(x -x<span>₁)
</span>y - -9 = -2(x - 10<span>)</span><span>
y + 9 = -2(x - 10) </span>
volume = 4/3 x pi x r^3
r^3 = 12.3^3 = 1860.867
1860.867 x 4/3 = 2481.156
answer = 2481.156pi cm^3
Answer is A
