Question

Check all of the points that are solutions to the system of inequalities.

y>4x + 3
-
x>1

A.(1, 11)
B.(1, 19)
C.(2, 11)
D.(4, 11)
E.(4, 19)
F.(1, -1)

Answer 1

only E.

Answer 2

looks like you can nix F

Answer 3

why not D?

Answer 4

only A, and B

Answer 5

I assume the problem is: y is greater than or equal to 4x+3 because of the - below; and x>1. If this is correct, then A, B and F can be eliminated because x in each case is equal to 1 and not greater than 1.

This leaves C, D and E:

C) y>=(4)(2)+3
11>=8+3
11>=11 This is a true statement

D) y>=(4)(4)+3
11>=16+3
11>=19 This is not a true statement

E) y>=(4)(4)+3
19>=16+3
19>=19 This is a true statement

Therefore, C and E would be correct if my assumption of the problem is correct
