Answer:

The two column proof is presented as follows;

Statement                   {}                  Reason

1. Parallelogram SUPN \overline {SR}⊥ \overline {UN} {}   1. Given

and \overline {MP}⊥ \overline {UN}

2. ∠SRU = ∠PMN = 90°   {}                 2. Definition of perpendicular lines

3. ∠SRU ≅ ∠PMN            {}                 2. Definition of congruency

4. \overline {UP} ║ \overline {SN}                      {}                4. Opposite sides of a parallelogram are                                            {}                                                               congruent

5. ∠SNR ≅ ∠PUM             {}               5. Alternate interior angles are congruent

6. \overline {UP} ≅ \overline {SN}                      {}               6. Opposite sides of a parallelogram are                                            {}                                                              congruent

7. ΔPMU ≅ ΔSRN                 {}           7. By AAS rule of congruency

By the Angle-Angle-Side (AAS) rule of congruency, we have that, if two angles and a corresponding adjacent side (∠SRU ≅ ∠PMN, ∠SNR ≅ ∠PUM, \overline {UP} ≅ \overline {SN})  of two triangles (ΔPMU and ΔSRN) are congruent, then the the two triangles are also congruent (ΔPMU ≅ ΔSRN)

Write the eguation of the line through (-8,-6) with slope = -5
Marta_Voda [28]

Answer:

Y=-5x-46.

Step-by-step explanation:

-5 is the slope, so Y=-5x+b. If you plug in (-8,-6), you get -6=40+b, so b has to be -46 for that to be true, I think.

What is the sum of -2/3 and -4/6
Elodia [21]
Make sure they have common denominators.

-2/3 x (2/2) = -4/6

-4/6 + -4/6  = -8/6

-8/6 = - 1 2/6

-1 2/6 or -1 1/3 simplified, is your answer

hope this helps
