Question 1028690
you have r(x) = x - 1/3 * x + 5


if i read this equation correctly, then it can be simplified to:


r(x) = 2/3 * x + 5, because x - 1/3 * x = 2/3 * x


so your equation becomes r(x) = 2/3 * x + 5.


you want to find r(c-3)


you replace x with (c-3) to get:


r(c-3) = 2/3 * (c-3) + 5


simplify this to get r(c-3) = 2/3 * c - 2/3 * 3 + 5


simplify further to get r(c-3) = 2/3 * c - 2 + 5.


this results in r(c-3) = 2/3 * c + 3.
