Answer:
B
Step-by-step explanation:
2x-5y=13.........(1) × 3
-3x+2y=13.......(2) × 2
6x - 15y = 39
-6x + 4y = 26
Adding
6x - 6x - 15y + 4y = 13 + 13
Answer:
I'm pretty sure it's C
Step-by-step explanation:
(x,y) goes into {3x_4, to get 3y_2
Answer:
Option 1 is correct.
Step-by-step explanation:
Given angle 
. we have to find the quadrant and the reference angle.
Angle given is 
Hence, the angle is 110° lies in second quadrant.
Now reference angle, the smallest angle that you can make from the terminal side of an angle with x-axis.
which is 
Hence, option 1 is correct.
It's called "solve the equation for 'y' ". That means move things
around so that you end up with 'y' all alone on one side, and
everything else on the other side.
You started with 9x - 7y = -7
Subtract 9x from each side: - 7y = -9x - 7
Divide each side by -7 : y = 9/7 x + 1
