If two angles are vertical angles, then they are congruent. if two angles are congruent, then their measures are equal. which of the following is valid, based on deductive reasoning? a. if two angles are not congruent, then their measures are not equal. b. if two angles are vertical angles, then their measures are equal. c. if two angles are congruent, then the two angles are vertical. d. if two angles are not vertical angles, then the two angles are not congruent.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is
