Answer:
This might be wrong but I think it is C
Step-by-step explanation:
3x-6=2x-6
3x=2x
x=0
You can see that if you plug in 0, you get: 3(-2)=2(-3)

<span>First, let’s simplify:
=> f+ 4/g
=> rewrite the given equation to fraction
=> <u>f + 4</u> x g = (6) x g (multiply
g on both sides) Then divide the equation
g
=> f + 4 = 6g (subtract the 4 on both sides)
=> (f + 4) – 4 = (6g) = 4
=> f = 6g – 4
Therefore the answer is f = 6g -4

Hello,
First, you must understand that
(f-g)(x) means f(x)-g(x) it is the difference of two functions :
f(x)=2x+4 and g(x)=3x-7
f(5)=2*5+4=10+4=14
g(5)=3*5-7=15-7=8
So, (f-g)(5)= f(5)-g(5)=14-8<u>=6</u>
Answer A: none of the choices are correct.
An other way to do it:
(f-g)(x)=f(x)-g(x)=2x+4-(3x-7)= 2x-3x+4+7=-x+11
if x= 5 then (f-g)(5)=-5+11<u>=6</u>
