Choose the correct description of the graph of the compound inequality: (5 points) x − 1 less than or equal to 7 or 2x greater than or equal to 22

A number line with an open circle on 8, shading to the left, and an open circle on 11, shading to the right
A number line with an open circle on 8, an open circle on 11, and shading in between
A number line with a closed circle on 8, a closed circle on 11, and shading in between
A number line with a closed circle on 8, shading to the left, and a closed circle on 11, shading to the right

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

c.)
