Answer:
X= -8
Step-by-step explanation:
4-12=-8
You must reverse the problem so that you are solving for x, rather than 4.
2x - 5 < 7
2x = 12
x = 6
4x + 10 > 6
4x = - 4
x = - 1
( - 1 , 6 )

answer
D ∩ (E ∩ F) = 4
Answer:
E: L is perpendicular to a line with slope
.
Lines are perpendicular if the negative reciprocal of the slope is equal. For example, the reciprocal of
is
(remember, to get the reciprocal, simply switch the numerator and the denominator).
So, the negative reciprocal of
is
. This represents the slope of a line that is perpendicular.
