Question

2. Which ordered pair makes the inequality true?

2x + y > 8

Answer 1

a) (–13, 0)
b) (–2, 13)
c) (0, 4)
d) (5, –3)

Answer 2

Ive been having troubles with it I have two problems like this.

Answer 3

test each point... lemme test the 1st one \(\bf 2x + y > 8\qquad (-13,0)\qquad x=-13\quad y=0\\ \quad \\
2(-13)+0>8\implies -26 > 8\)

now, is -26 really BIGGER than 8? not quite, thus is false, thus is not a solution

now test the others, see which one gives you a valid inequality

Answer 4

2X+y>8
a) (-13,0) -26+0>8 not true
b) (-2,13) -4 + 13 >8 or 9>8 this is true
c) (0,4) 0 + 4 > 8 not true
d) (5, -3) 10 - 3 >8 or 7 > 8 not true

Answer 5

inequalities are confusing for many people!

Answer 6

Which ordered pair makes the equation true?

4x – 9y = –5

(Points : 1)
(–5, –2)
(–1, 1)
(10, 5)
(20, 4)

Answer 7

valid inequalities, will be say 3 > 1 or 4 > 3 or -1 > -3 and so on

invalid ones will be... say 2 < 1 because 2 is not really less than 1
or 3 < 4 or 5 > 7

Answer 8

so you plug in the given "x" and "y" in the ordered pair, and see what you get

Answer 9

ok thank you
