The functions f(x) and g(x) are defined below.
f(x)=x-16/x^2+6x-40' for x = -10 and x = 4
g(x)= 1/x+10' for x = -10

which expression is equal to f(x) + g(x)?

a. x-15/x^2+7x-30

b. x-15/x^2+6x-40

c. 2x-20/x^2+6x-40

d. 2x-12/x^2+6x-40

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

it should be a.

hope it
