Which number line shows the graph of x≤6
?

Answers

Answer:

C

Step-by-step explanation:

There is a line under the "<" sign which means that "x" can be equal to 6. The arrow going left shows that x is less than 6 and the dot being shaded mean that 6 can be an answer so the number line C is the answer. Hope this helped:)

The required number line that shows the expression x ≤ 6 is figure C. Option C is correct.


What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

What is a number line?

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
The expression x ≤ 6 implies that the domain of the x is a set of a real number less than and equal to 6, so all values represented on the number line below and equal to 6 is bold dark.

Thus, the required number line that shows the expression x ≤ 6 figures C. Option C is correct.

Trend lines
Help will be greatly appreciated!
The manager of fast food restaurant collected data to study the relationship between the number of employees working registers and the amount of time customers waited in line to order. He made a scatter plot of the data and credited a trend line with the equation y= -70x+300, where y is the total amount of time waited in seconds and x is the number of employees working registers.
