1)
elements that satisfy x-0.6 > 0 are 1,√2,2,4
2)
elements that satisfy x^2-1 > 1 are 1,1/2,0,-1,-2
3)
elements that satisfy 10x-9 ≥ x are 1,2,4,√2
Let S = {-2, -1, 0, 1/2, 1, √2, 2, 4}. Determine which elements of S satisfy the inequality. (Select all that apply.)
x - 0.6 > 0
wouldnt all but -2,-1, 1/2 and 0 work? i tried entering this but it said i was wrong.
Let S = {-2, -1, 0, 1/2, 1, √2, 2, 4}. Determine which elements of S satisfy the inequality. (Select all that apply.)
x2 - 1 < 1
i tried all but 2 and 4 but again im wrong for some reason.
Let S = {-2, -1, 0, 1/2, 1, √2, 2, 4}. Determine which elements of S satisfy the inequality. (Select all that apply.)
10x - 9 ≥ x
-2
-1
0
1/2
1
√2
2
4
None of them
no idea on this one
