(A) 5x+2y=21
(B) -2x+6y=-34
multiply (A) by - 3→ -15x - 6y = - 63 (C)
Now add (C) to (B):
-15x - 6y = - 63 (C)
-2x + 6y =-34 (B)
----------- --------
-17x = - 97 and x = 97/17
Now replace x value in any of the equation and you'll find y = - 64/17
1st Answer (97/17 , - 64/17)
2nd Answer : 97/17 + (-64/17) = 97/17 - 64/17 = 33/17 ≈ 2
Given:
m∠NRQ = 60°
To find:
The angle measure of minor arc NQ
Solution:
The inscribed angle is half of the intercepted arc.

Multiply by 2 on both sides.


Substitute m∠NRQ = 60°.


The measure of minor arc NQ is 120°.
C is the answer because the X factors can’t repeat
