Answer:
f(7) =5
Step-by-step explanation:
f(x) = x - 2
f(7) means let x = 7
f(7) = 7-2
f(7) =5
Given a radius , the volume of a sphere is given by
We can solve this formula for the radius, given the volume:
We can plug our value for the volume to get the radius:
I'd suggest re-wording your question:
"How do I find the ordered pair (x,y) that solves this system of linear equations?"
One way of doing that would be to substitute y=5x+7 into the other equation:
-3x - 2(5x+7) = -12. Solve this for x. Once you have a value for x, subst. that value into y=5x+7 to find the corresponding y value.
Then write the ordered pair (x,y). That's it.
To find the other factor you just divide the first factor by the area and you get (x-6)
And you can check by multiplying both the factors by each other.
(X+8)(X-6)
x^2+2x-48
