X=5 because you add 2 to both side and get 3x=15, and then you divide both sides by 3 to get x alone, and get 15/3 which equals 5

Start with

$3x-2=13$

Add 2 to both sides

$3x=15$

Divide both sides by 3

$x=5$

Given the following functions, find and simplify (f • g)(x) f(x)=—x+3 g(x)=-x-1

Hitman42 [59]

Answer:

$(f\circ g)(x)= x + 4$

Step-by-step explanation:

Composite Function

Given f(x) and g(x) as real functions, the composite function $(f\circ g)(x)$ is defined as:

$(f\circ g)(x)=f(g(x))$

It can be found by substituting g into f.

We are given the functions:

f(x) = -x + 3

g(x) = -x -1

Find

$(f\circ g)(x)=f(g(x))= - (-x -1) + 3$

Removing parentheses:

$(f\circ g)(x)= x + 1 + 3$

Simplifying:

$\mathbf{(f\circ g)(x)= x + 4}$

A local hamburger shop sold a combined total of 525 hamburgers and cheeseburgers on Monday. There were 75 more cheeseburgers sol

max2010maxim [7]

Answer: 225 hamburgers were sold on Monday.

Step-by-step explanation:

525 = h + c

h = hamburger

c = cheeseburger

c = 75 + h

h + (h + 75) = 525

2h + 75 = 525

-75

2h = 450

h = 225
