Answer:
C
Step-by-step explanation:
You automatically know that it is not A. The dot is filled in on the number line, so it must have a line under the inequality mark.
The number line says that x is greater than or equal to 2.5
Key:
gtoet means greater than or equal to
ltoet means less than or equal to.
B:
3x + 2 gtoet 17
3x gtoet 15
x gtoet 5
This is incorrect. X is not gtoet 5.
C:
12 + 4x gtoet 22
4x gtoet 10
x gtoet 2.5
This is correct. X is gtoet 2.5
D:
-6x - 15 gtoet 0
-6x gtoet 15
(The sign switches in this one because you are dividing by a negative)
x ltoet 2.5
Incorrect. X is not ltoet 2.5
