2x + y = 10 y = -2x + 8

4 0

By using substitution, this equation will be easy to solve. Plug the second equation into the first equation and solve like you normally would to find x, then use that x value to plug it into y.

2x+(-2x+8)=10

8=10

In this case, the variable was cancelled out itself, which means that this problem is undefined.

Name a pair of overlapping congruent triangles in each diagram. State whether the triangles are congruent by SSS, SAS, ASA, AAS,

MariettaO [177]

Answer:

ΔPTS≅ΔRTA by AAS axiom of congruency

Step-by-step explanation:

Consider ΔPQA and ΔRQS

∠PQA=∠RQS (Vertically Opposite Angles)

∠QAP=∠QSR (Complementary of two equal angles, ∠RAT and∠PST)

Due to angle sum property of a triangle, we come to the conclusion that

∠APQ=∠SRQ

Consider ΔPTS and ΔRTA

TA=TS (Given)

∠RAT=∠PST(Given)

∠APQ=∠SRQ (Proved above)

Therefore, ΔPTS≅ΔRTA by AAS axiom of congruency.
