The solution of the equation is given by (-2,-1), This is represented by option C.
<h3>What is a System of Equations?</h3>
A system of equations is a set of equation that have a common solution.
The solution of the equations can be determined by using the Elimination and Substitution method
3x-5y = -1
2x-y = -3
-7x = 14
x = -2
Substituting this value in the equation
3 * (-2) -5y = -1
-6 -5y = -1
-5y = 5
y = -1
Therefore, the solution of the equation is given by (-2,-1), This is represented by option C.

i belive it is y=-4x+5
Step-by-step explanation:
i just did the test
Answer:
The answer is 9
Step-by-step explanation:
If you subtract 8-(-1) you would get 9.
M= -8 - -5/ 3 - 15= -8+5/3-15= -3/-12 = 3/12 = 1/4
The slope is 1/4.
The slope formula is m=y2-y1/x2-x1. I plugged in -8=y2, -5=y1, 3=x2, and 15=x1. Then I solved it.
Answer:
215°
Step-by-step explanation:
Add multiples of 360° until you get an angle in the desired range:
∠B = -865° + 3×360° = 215°
