from the following figure, how many ways can you show that lines l and m are parallel? at least 4 ways one way two ways three ways

The correct answer is: At least 4 ways.

At least 4 ways.

Step-by-step explanation:

There are 4 basic ways of showing that two lines are parallel.

Show that consecutive exterior angles are supplementary.

Clearly from the figure we can show the first four properties easily.

Hence, the answer is:

At least 4 ways.

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

the answer is $42.96
