Answer:

X = 4

Step-by-step explanation:

In the equation add 3 to both sides of the equation

1/2x-3+3=2-3/4x+3

Simplify

1/2x = -3/4x + 5

Add 3/4x to both sides

1/2x + 3/4x = -3/4x + 5 + 3/4x

Simplify

5/4x=5 Multiply both sides by 5

5x=20 divide both sides by 5

5x divided by 5 and 20 divided by 5

In the piece-wise function graphed below, which is the correct equation for when − 2 ≤ x ≤ 2

Rama09 [41]

Answer:

$y=-\frac{1}{2}x+2$

Step-by-step explanation:

Looking at the graph

For x=-2 ---> f(x)=3

For x=2 ---> f(x)=1

we have the points

(-2,3) and (2,1)

Find the slope

$m=(1-3)/(2+2)=-\frac{1}{2}$

The equation of the line in slope-intercept form is equal to

$y=mx+b$

we have

$m=-\frac{1}{2}$

$b=2$ ---> see the graph

substitute

$y=-\frac{1}{2}x+2$
