Question

I quite do t understand will I be now to help mrunderstand. Please answer question 6

Answer 1

A number line is a horizontal line that has points that correspond to numbers. We can graph inequalities on the number line. The solution to an inequality is a range of numbers hence we use an arrow. The following graph represents the inequality x≤2

The black dot shows that 2 is included in this range.

The compound inequality shown in the graph can be obtained by

1. First identify the point where the circle is located.

2. If it is shaded, then the point is included in the inequality

3. If the arrow faces left, the inequality is a less than sign otherwise it is greater than sign.

Hence:

`x\text{ }<\text{ 0 or }x\text{ }\ge\text{ 4}`

Question 7

Similar to what we did in question 6,

The solution is:

`x\text{ }<\text{ -6 or x }>\text{ -3}`
