I am sorry, I would love to help but I am not sure. Good luck anyways. :(
I’m pretty sure it would be a and b
the numbers inside the () are first number is x second number is y so it is (x,y)
so for y<x the second number needs to be smaller than the first number
so right away (3,3) is not the answer
and then y also has to be greater then 2x-3
so replace x with the fist numbers and see what you get.
(2x2)-3 = 4-3 = -1 since -1 is not greater than -1 the second answer (2,-1) is not right
3rd one (-1,-2) 2(-1)-3 = -2-3=-5
so -2 is greater than -5 and -2 is less than -1 so the 3rd one is the answer
Answer:
4.................=y......
The standard equation of a circle:
(h, k) - center
r - radius
We have:
(2, -8) → h = 2, k = -8
r = 9
Substitute:
