Which number(s) is/are a solution of the inequality? There can be more than one correct answer.

a) 1 b) -2 c) 5 d) 2

Answer 3

the <= means smaller or equal to..
so the number you choose to replace y has to make the equation equal or bigger than 20.

for example: if you choose a) 1

20 <= 1(10-1)
20 <= 1(9)
20 <= 9, which is false. 20 is not smaller or equal to 9!
Try this with all the options and you should find the correct one, good luck!
