The answer is: 
Answer:
B would be the only answer that is within the domain of this function.
Step-by-step explanation:
Range refers to the y values of the graph. This graph has the range of (∞,2 ], [ -2,∞). Therefore, out of these 3 options, B is the only answer within that range.
Answer:
(2,-3)
Step-by-step explanation:
I am not sure if you meant the first equation to be y or -y. I solved it as y.
y = x-5 -x -3y =7
I am going to take the second equation and write it as x =
-x - 3y = 7 Give equation
-x = 3y +7 Add 3y to both sides
x = -3y-7 Multiplied each term in the equation by -1 so that x could be positive
I am going to substitute -3y-7 for x in the first equation up above
y = x - 5
y = -3y -7 - 5 Substitute -3y-7 for x
y = -3y -12 Combined -7-5
4y = -12 Added 3y to both sides
y = -3 Divided both sides by 4.
I now know that y is -3, I will plug that into x = -3y-7 to solve for x
x = -3(-3) -7
x = 9-7 A negative times a negative is a positive
x = 2
360 - because a right angle is 90° and there are 4 right angles in a circle , 90 x 4 = 360
