Answer:

Step-by-step explanation:

a).

2.2 × 10^{-3} + 9 × 10^{-4} =

2.2 × 10^{-3} + 0.9 × 10^{-3} =

( 2.2 + 0.9 ) × 10^{-3} = <em>3.1 × </em>10^{-3}

b).

2.2 × 10^{-3} - 9 × 10^{-4} =

2.2 × 10^{-3} - 0.9 × 10^{-3} =

( 2.2 - 0.9 ) × 10^{-3} = <em>1.3 × </em>10^{-3}

What is different between solving inequalities and absolute value inequalities?
Ivenika [448]

Answer:

The absolute number of a number a is written as

|a|

And represents the distance between a and 0 on a number line.

An absolute value equation is an equation that contains an absolute value expression. The equation

|x|=a

Has two solutions x = a and x = -a because both numbers are at the distance a from 0.

To solve an absolute value equation as

|x+7|=14

You begin by making it into two separate equations and then solving them separately.

x+7=14

x+7−7=14−7

x=7

or

x+7=−14

x+7−7=−14−7

x=−21

An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.

The inequality

|x|<2

Represents the distance between x and 0 that is less than 2

Whereas the inequality

|x|>2

Represents the distance between x and 0 that is greater than 2

You can write an absolute value inequality as a compound inequality.

−2<x<2

This holds true for all absolute value inequalities.

|ax+b|<c,wherec>0

=−c<ax+b<c

|ax+b|>c,wherec>0

=ax+b<−corax+b>c

You can replace > above with ≥ and < with ≤.

When solving an absolute value inequality it's necessary to first isolate the absolute value expression on one side of the inequality before solving the inequality.
