Which of the following represents the solution to the inequality 2 | 5 - 2x | - 3 ≤ 15

Oksanka [162]

Answer:

[-2,7] is the solution of inequality .

Step-by-step explanation:

Given : inequality 2 | 5 - 2x | - 3 ≤ 15

To find: solution of inequality.

Solution : We have given that 2 | 5 - 2x | - 3 ≤ 15 .

On adding 3 both sides:

2 | 5 - 2x | - 3+3 ≤ 15 +3

2 | 5 - 2x | ≤ 18.

ON dividing both side by 2 and simplify

| 5 - 2x | ≤ 9.

On applying absolute rule, if | u | ≤ a,a> then -a ≤ u≤ a

-9≤5 - 2x ≤ 9.

5 - 2x ≤ 9 , 5 - 2x ≤ -9.

- 2x ≤ 9-5

- 2x ≤ 4

On dividing by -2

x ≥ -2.

For 5 - 2x ≤ -9.

- 2x ≤ -9-5

- 2x ≤ -14

On dividing by -2

x ≤ 7

Therefore , [-2,7] is the solution of inequality .

You are looking at ratios.
There are 640:460 females to males.
Basically, the males got 460/640ths of 42,000 dollars.
This will take a few seconds with a calculator.
I get $30, 187.50.

Therefore, B. $30,190 wouldbe the closest to the correct answer.

Answer:

$\sqrt{x - 5} + 4$
$3 \sqrt{x + 3} + 2$
$- \sqrt{x + 2} - 2$
$- 2 \sqrt{x} + 3$
Type these function in for 1a,1b,2a,2b respectively and look for table of values
