Both define y, so they are equivalent.
5x-9=2x+6
3x-9=6
3x=15
x=5
Then plug in x into any of the equations
y=2(5)+6
y=10+6
y=16
Final answer: (5,16)
10,15,20,25,30

Answer:
SAS, Triangle ABC is congruent to triangle DEF.
Step-by-step explanation:
We name triangles with a triangle symbol and in alphabetical order. To write a statement, name each triangle and place a congruent sign between them.
To determine what postulate, look at the arrangement of congruent parts which is side-angle-side. This is SAS.
Answer: x=40°
Step-by-step explanation:
The two triangles are congruent (I think it’s called the interior angle proof) so the bottom right angle is also 65°. All angles in a Triangle equal 180°, so 180-(75+65)=40
