Will mark brainliest. the congruency of mno and xyz can be proven using a reflection across the line bisecting oz. however, this congruency can also be proven using geometric postulates, theorems, and definitions. prove that the triangles are congruent using a two-column proof and triangle congruency theorems. will mark !

answer:

reason

1.given

2.given

3.given

4.congruent side substitute equal side

5.being common side

6.adding statement 4 and 5

7.whole part axiom

8.equal side substitute equal congruent side.

9. by a.a.s axiom

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
