Identify the reason that justifies the statement.
Amiraneli [1.4K]

Answer:

C; Substitution property

Step-by-step explanation:

Here, we want to find the justification that justifies the written equation;

If PQ + RS = PS

and RS = XY

then PQ + XY = PS

What we simply did is to substitute RS for XY in the second equation;

The correct answer is Substitution property

It can be fully referred to as the substitution property of equality.

What it simply means in a nut shell is that since XY and RS are equal, then in any addition or arithmetic equation, we can make a substitution of XY for RS since they are equal to each other

Solve the following inequalities by expressing the solution in interval form and on the number line:
Nookie1986 [14]

The value of x is from negative infinity to negative 3/7 and 29 to positive infinity.

<h3>What is inequality?</h3>

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality equations are given below.

a)  - 9x + 7 > 16 + 12x

b)  18 + 13x < 14x - 11

Then

a)  - 9x + 7 > 16 + 12x

Solving for x, we have

21x < -9

  x < -3/7

The value of x is less than the negative of 3/7.

b)  18 + 13x < 14x - 11

Solving for x, we have

x > 29

The value of x is greater than 29.

More about the inequality link is given below.
