Question

.02] Which of the following is not an equivalent form of the compound inequality

x - 1 < -10 or x + 12 > 12

A number line with an open circle on -9, an open circle on 0, and shading in between.

x < -9 or x > 0

A number line with an open circle on -9, shading to the left, and an open circle on 0, shading to the right.

x > 0 or x < -9

Answer 1

what if you were to solve for "x"
x - 1 = -10

what would that give you?

Answer 2

ok if we were to solve for "x" on both inequalities

1st
x - 1 < -10
# adding 1 to each side
x < -9

now the 2nd one
x+12 > 12
#substracting 12 from each side

x > 0

so
now we know that x < -9 and x > 0
