Question

Which of the following ordered pairs is not a solution to the inequality y > -3x + 5?

(0, 6)

(2, 0)

(-1, 9)

(1, -1)

Question 13 (Multiple Choice Worth 4 points)

[5.01] Choose the correct description of the graph of the inequality -2x >/= 10.

Open circle on -5, shading to the left.

Closed circle on -5, shading to the left.

Open circle on -5, shading to the right.

Closed circle on -5, shading to the right.

Answer 1

to find which ordered pair satisfies the inequality, plug in the first coordinate of the ordered pair into the x in the inequality and plug the second coordinate into the y for the problem. then simplify. if the simplification is true, then that ordered pair is a solution to the inequality

Answer 2

@AriPotta

Answer 3

you should do what @etemplin told you to :)

Answer 4

for A its between C or D right>??

Answer 5

y > -3x + 5

(0, 6) (2, 0) (-1, 9) (1, -1)

6 > -3(0) + 5
6 > 5
true.

0 > -3(2) + 5
0 > -6 + 5
0 > -1
true.

9 > -3(-1) + 5
9 > 3 + 5
9 > 8
true.

-1 > -3(1) + 5
-1 > -3 + 5
-1 > 2
false.

so you're answer is d

Answer 6

your*

Answer 7

ok... now for the second answer it has to be between B and D because its a CLOSED thing right?

Answer 8

yea

Answer 9

the shading??? how do i find that again?

Answer 10

plug in a number that wouldnt make the inequality equal. if that number makes the inequality true, then shade in the direction of that number...
for example, if your inequality was x<5, plug in 0 for x. since 0<5, shade in the direction of 0

Answer 11

what do we do?
