If I'm reading your question correctly: "<span>F(x)=7x+9/8x-9 when -f(x)," then all you have to do to find -f(x) would be to put a negative sign in front of ALL
of 7x + 9 / (8x-9):
9
- f(x) = -7x - --------
8x-9</span>
Working backwards again:
3/2= 1.5
1.5 is the second term.
1.5/2= .75
.75 is the first term.
2(x+14) + 2(x) after using the distributive property will be 2x+28+2x. What I did to find this is multiply the number outside of the opening parentheses by everything inside of the pair of parentheses.
