1) substitute 10x in for the equation.
403.2 cubed inches because 3 times 4 times 3.14 is 403.15 which rounds to 403.2
(y^12)/5
9/45=1/5
x^5/x^5=1
y^16/y^4=y^12
A is the correct answer.
Point Slope Form: y - y₁ = m(x - x₁)
m = slope ⇒ -4/7
Coordinate: (-1 , 4)
x₁ y₁
All you have to do is plug in all of the information above into the formula.
y - 4 = -4/7(x +1)
Round
321.786 is about 322
240.23 is about 240
322+240=562
about 562
