Question

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







x+15≤12
and
x+15≥5


A. 2 greater than or equal to x + 15 greater than or equal to 5

B. -3 greater than or equal to x greater than or equal to -10

C. A number line with a closed circle on -10, a closed circle on -3, and shading in between.

D. A number line with a closed circle on -10, shading to the left, and a closed circle on -3, shading to the right.

Answer 1

\[x+15\leq 12\\
x\leq -3\]

Answer 2

\[x+15\geq 5\\
x\geq -10\]

Answer 3

so
\[-10\leq x\leq -3\] shade the stuff between \(-10\) and \(-3\) and use closed circles because of the \(\leq\) instead of \(<\)

Answer 4

Oh, I see :3
