$\frac{72}{9} =\frac{56}{3x-20}\\8=\frac{56}{3x-20}\\8(3x-20)=56\\3x-20=7\\3x=27\\x=9$

10 points <br> Can someone please do number 4

Andrei [34K]

This question wants to know the domain. For example: (2,4) 2 is the domain and 4 is the range.

Then, they want you to solve by finding X the range when x =-1

x-4/x^2+5x-36

Put -1 everytime you see x

-1-4/-1^2+5(-1)-36

-5/1+(-6)-36

-5/-41 This is the range.
