Answer:
(5,-5) and (10,-4) are the only valid solutions given
Explanation:
To solve this solution set we will plug in values of x and y to verify if they are true.
(5,-5) 10-(-25) greater than 25? true
15-45 less than 9? true meaning 5,-5 is a answer to this set
(10,-4) 20+20 = 40>=25 True
30-36=-6<9 true
(3,0) 6-0 >= 25 ? False
(1,-10) 2-5(-10)>= 25 ? True
3+9(-10)<9 ? false
(0,1) 0 - 5>= 25? false
(15,-1) 30+5>=25? true
45-9<9?false
