To which subset of real numbers does the number 1/5 belong?

nasty-shy [4]

Answer: Option 'B' and 'C' are correct.

Step-by-step explanation:

Since we know that irrational numbers are those real number which cannot be written in $\frac{p}{q}$ form.

Rational numbers are those real numbers which can be written in $\frac{p}{q}$ form.

Inverse property of multiplication is that property in which we write a number in reciprocal form .

Whole numbers starts from 0 and Natural numbers start from 1 and Integers contain both positive and negative numbers.

Hence, $\frac{1}{5}$ belongs to rational numbers sets and inverse property of multiplication sets.

Therefore, Option 'B' and 'C' are correct.

Solve the compound inequality. Graph your solution. 2x – 2 < –12 or 2x + 3 > 7 x < –5 or x > 5 x < –5 or x > 2

Brilliant_brown [7]

Answer:

The solution region is x < –5 and x > 2

Step-by-step explanation:

We are given the inequalities, 2x–2 < –12 or 2x+3 > 7

Upon simplifying the inequalities, we get,

A. $2x-2 < -12$

$2x-2 < -12$ i.e. $2x < -10$ i.e. $x < -5$

B. $2x+3 > 7$

$2x+3 > 7$ i.e. $2x > 4$ i.e. $x > 2$

So, we get the solution is $x$ or $x>2$ and the plotted region can be seen below.
