Question

Which of the following is not an equivalent form of the compound inequality?

x + 6 > 15 or x + 6 less than or greater to 12

A x > 9 or x less than or greater to 6
B x less than or greater to 6 or x > 9
C A number line with an open circle on 9, shading to the right, and a closed circle on 6, shading to the left.
D A number line with an open circle on 9, a closed circle on 6, and shading in between.

Answer 1

x > 9
"x + 6 less than or greater to 12 " is this a typo?

nope @jennychan12

Answer 3

hmm, i dunno then sorry

Answer 4

x + 6 > 15
x > 15 - 6
x > 9

x + 6 <> 12 (this is how you have it written ?)
x <> 12 - 6
x <> 6

ANSWER : c and d are not equivalent....the reason being, is that there will be no closed circles because there is no equal signs.
