Which of the following is the correct graph of the solution to the inequality −18 > −5x + 2 ≥ −48?

monitta

Answer:

Option D. A number line with an open circle on 4 with shading to the right and a closed circle on 10 with shading to the left

Step-by-step explanation:

we have

$-18 > -5x+2 \geq -48$

Divide the compound inequality into two inequalities

$-5x+2 \geq -48$ -----> inequality A

$-5x \geq -48-2$

$-5x \geq -50$

Multiply by -1 both sides

$5x \leq 50$

Divide by 5 both sides

$x \leq 10$

The solution of inequality A is the interval ----> (-∞,10]

All real numbers less than or equal to 10

$-18 > -5x+2$ -----> inequality B

$-18-2 > -5x$

$-20 > -5x$

Multiply by -1 both sides

$20 < 5x$

Divide by 5 both sides

$4 < x$

Rewrite

$x > 4$

The solution of the inequality B is the interval ----> (4,∞)

All real numbers greater than 4

The solution of the compound inequality is

(-∞,10] ∩ (4,∞)= (4,10]

All real numbers greater than 4 and less than or equal to 10

A number line with an open circle on 4 with shading to the right and a closed circle on 10 with shading to the left

What is the range of the function graphed below?

Nadusha1986 [10]

Its the second option!

The range expresses the constraints of y-values of a function. There is a solid point at positive three which means that it is included. The open point at -3 means it’s not included. This makes the range -3
