Answer:
Pythagorean theorem is D
Step-by-step explanation:
It is used to find the missing length of a right angled triangle.
The solution of the equations is (-2, -1)
<h3>System of equation:</h3>
2x - 3y = -1
11x - 9y = -13
Using elimination method let multiply the first equation by -3.
Therefore,
-6x + 9y = 3
11x - 9y = -13
5x = -10
x = -10 / 5
x = -2
let's find y as follows;
2(-2) - 3y = -1
-4 - 3y = -1
-3y = -1 + 4
-3y = 3
y = 3 / -3
y = -1

Answer:
im sorry i dont know but this is for a challenge sorry
Step-by-step explanation:
Yes it is symmetrical because both sides are the same
Because you can't do it.
