Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Answer to Problem 35PPS

  h≤−7

  Pre-Algebra Student Edition, Chapter 5.5, Problem 35PPS , additional homework tip 1

Explanation of Solution

Given information:

  8(2h+6)≤12h+20

Concept Used:

When two quantities are not equal, the comparison between them is often presented by certain symbols, this comparison is known as inequality and the symbols used for such comparison are known as inequality symbols.

There are four inequality symbols, > , < , ≥ , ≤ namely “greater than”, “less than”, “greater than or equal to” and “less than or equal to” respectively.

On a number line, integers are placed at an interval of one and value if integers increases as we move left to right on the number line.

Calculation:

  8(2h+6)≤12h+20⇒8(2h)+8(6)≤12h+20   ⇒16h+48≤12h+20                             ⇒16h+48−48≤12h+20−48⇒16h≤12h−28⇒16h−12h≤12h−28−12h⇒4h≤−28⇒4h4≤−284⇒h≤−7

Graph:

In the inequality h≤−7 we can say h in smaller than or equal to −7 and can plot the same on number line-

We will make a closed dot on −7 as it is not included in the inequality and then move towards left as h in smaller than −7 .
