From other source on the internet this question is:

Which absolute value expression represents the distance between 3 and - 2 on a number line?

Both are equivalent.

Explanation:

The distance between two numbers in a number line is the absolute value of the difference between the two numbers.

Thus, the distance between a number x and a number y is |x - y|, which is also equivalent to |y - x|.

In this case the distance between 3 and - 2 can be represented by either of the expressions:

Note that when you simplify them you get the same value:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
