Answer:
The additive inverse of 7 is −7, because 7 + (−7) = 0; The additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0.
I hope I'm right and good luck! :)
Lets say original price is x
x-40% of x =130
x=216
The final expression would be -5x -50.
You could've got this by multiplying -5 and x together, which is -5x.
Multiply -5 and 10 together, and you get -50.
This is also called the Distributive Property. Hope this helped :)
Ok so f(x) and g(x) are the same thing as y. this means that you can solve these equations the same as any other multi-step equation. the only difference is if they have a number other than x in the parentheses. if they have a number you will just replace the x’s in the equation with the number in the parentheses.
example:
regular equation equation with f(4)
f(x)=2x+1 f(4)=2(4)+1
