Question

Determine which ordered pairs are part of the solutions set for the inequality.

y is less than or equal to x + 2.
A. (-1, 1)
B. (0, 3)
C. (2, 4)
D. (3, 2)
True or False: The point (0, 7) is a solution to y is less than or equal to negative 3 x + 7.
True
False

Answer 1

Using the equation see if y is equal to or less than x+2 when you plug the numbers in.

Answer 2

nelson is correct...you are going to have to sub your answer choices into the inequality and see which one is true.

y <= x + 2
A. (-1,1) x = -1 and y = 1
now sub
1 <= -1 + 2
1 <= 1 (this one is correct)

B. (0,3) x = 0 and y = 3
3 <= 0 + 2
3 <= 2 (incorrect)

C. (2,4) x = 2 and y = 4
4 <= 2 + 2
4 <= 4 (this one is correct)

D. (3,2) x = 3 and y = 2
2 <= 3 + 2
2 <= 5 (this is correct)

your solutions can be A, B, and D.

=======================
y <= -3x + 7
(0,7) x = 0 and y = 7
now sub
7 <= -3(0) + 7
7 <= 0 + 7
7 <= 7
TRUE. ....7 is equal to 7

Answer 3

omg thanks so much

Answer 4

sure thing :)
