The inequality written in interval notation is therefore -4<x<-1 or (-4, -1)
<h3 /><h3>What are inequalities?</h3>
Inequalities are expressions separated by the mathematical inequalities ≤, ≥, < and >
For instance a < b is a form of inequality.
<h3>What is a number line?</h3>
A number line is a line on which numbers are marked at intervals, used to illustrate simple numerical operations.
From the given number line, we can see that closed circles are on -4 and -1. The inequality written in interval notation is therefore -4<x<-1 or (-4, -1)

To determine the rate of a number do the following steps:
Multiply the number by the percent (e.g. 87 * 68 = 5916)
Divide the answer by 100 (Move decimal point two places to the left) (e.g. 5916/100 = 59.16)
Round to the desired precision (e.g. 59.16 rounded to the nearest whole number = 59)
Answer:
See below ~
Step-by-step explanation:
<u>(a)</u>
The point (8, 28) represents that in the time of 8 minutes, 28 cm of the horse trough has been filled.
- 8 <u>minutes</u> 28 <u>centimeters</u>
<u></u>
<u>(b)</u>
<u>Finding the unit rate</u>
- No. of centimeters / min.
- 28 cm / 8 min
- <u>3.5 cm/min</u>
