Solve |x| > -9.
{x|x < -9 or x > 9}
all reals
no solution

all real numbers

Step-by-step explanation:

|x| > -9

x is in the absolute value so any number of x will be positive or at least 0 and always greater than -9. So then the answer is all real numbers

To solve an inequality with absolute values, we use the theorems which states:

So, the given expression is the second case. Now, we just replace each value:

This result means that all solution from the given inequality are more than 9 or less than -9.

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 : )
