Math
So the ans would be 28-3x.

Math (is this correct)
The functions f and g are defined by: f:x 3x+1 g:x 9-x Determine an expression for the function gf(x) 3(9-x)+1 27-3x+1

math (how do i solve the last part)
The functions f and g are defined by: f:x 3x-2 g:x 2x+5 Evaluate:g(-6), fg(3) g(-6)= 2(-6)+5= -7 fg(3)= 3(2x+5)-2 6x+15-2 6(3)+13 = 31 Evaluate f(x)=8, calculate the value of x

This is my sons math problem I am not good at math please can you help me and show the work for the calculations " ALI MADE A MODEL FOR 624 USING 6 HUNDREDS, 2 TENS, AND 4 ONES. WHAT IF ALI HAD NOT HAD ANY TENS? HOW COULD SHE HAVE MODELED 624 WITHOUT USING TENS?...

math
x-2/3x+1,determine the inverse. x= y-2/3y+1 x (3y+1)=y-2 3xy+x=y-2 (where do i go from here if i am going right)

math
Completely Factor: x^2-Y^2-5x+5y

math (show me the working pls)
Completely factor: x^2-y^2-5x+5y

math (if someone could show me the working pls)
calculate the difference of the square using the following formula a^2-b^2=(a+b) (a-b) 1)28^2-12^2
