Question

let f(x)=-2x+4 and g(x)=-6x-7. find f(x)-g(x) ... medal and fan

Answer 1

if you can show me so i know how to do it.. because i need to learn this

Answer 2

all you do is take each equation substitute them in for f(x) and g(x)
so you have:
f(x)=-2x+4
g(x)=-6x-7

they ask you to find f(x)-g(x). so you take both equations and substitute the equations in. so instead of having:
f(x)-g(x)

it now looks like this
(-2x+4)-(-6x-7)

simplify it and multiply the - to the (6x-7) to get the simplified form:
-2x+4+6x+7

then you should know how to go from here. hope that helped

Answer 3

no :/ ...i need further help, if you dont mind

Answer 4

Only issue with that is it would be difficult if you simplified it.

Answer 5

4x+11

Answer 6

add like terms from -2x+4+6x+7
you would add -2x+6x to get 4x
then you add 4+7 to get 11
the final equation should look like
4x+11

hope that helped

Answer 7

thats it? awesome! thank you

Answer 8
