How to solve each inequality and graph it's solution

Step-by-step explanation:

First, graph the "equals" line, then shade in the correct area.

There are three steps:

1) Rearrange the equation so "y" is on the left and everything else on the right.

2) Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

3) Shade above the line for a "greater than" (y> or y≥)

or below the line for a "less than" (y< or y≤).

hope this helpled :)

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
