If f(x)=3x-1 and g(x)=x+5, find (f o g)(x) and (g o f)(x)<br><br> (f o g)(x)=<br><br> (g o f)(x)
Nuetrik [128]

Answer:

(f o g)(x)= 3x + 14

(g o f)(x) = 3x + 4

Step-by-step explanation:

(f o g)(x) = f(g(x)) = f(x + 5) = 3(x + 5) - 1 = 3x + 15 - 1 = 3x + 14

(g o f)(x) = g(f(x)) = g(3x - 1) = 3x - 1 + 5 = 3x + 4

4x-1 + 2x-1 = 5x how do I solve this problem?
GREYUIT [131]

Answer: 2=x

Step-by-step explanation:

4x-1 + 2x-1 = 5x

First combine like terms together

4x-1 + 2x-1 is 4x+2x-1-1

4x+2x-1-1 =6x-2

4x-1 + 2x-1=6x-2

6x-2=5x

The oppisite of 6x is -6x so -6x on both sides of equation to keep it balanced

6x-6x-2=5x-6x

0-2=-1x

-2=-1x

Divide both sides of the equation by -1 since -1 is being multiplied by x and the oppisite of multiply is divide

-2/-1=-1x=-1

2=x
