Acompound inequality using the variable x is 7 < x < 14 as in a graph

see the explanation

Step-by-step explanation:

we have the compound inequality

The compound inequality can be divided into two inequality

x > 7 -----> inequality A

The solution of the inequality A is the interval ----> (7,∞)

x < 14 ----> inequality B

The solution of the inequality B is the interval ----> (-∞,14)

The solution of the compound inequality is

(7,∞)  ∩  (-∞,14)=(7,14)

The solution is all real numbers greater than 7 and less than 14

In a number line the solution is the shaded area at the right of x=7 (open circle) and at left of x=14 (open circle)

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
