Answer: Choice B 
=============================================
Explanation:
The endpoint is at 4.5 and this endpoint is a filled in circle. So we'll have "or equal to" as part of the inequality sign. This is because we are including the endpoint as part of the shaded solution region.
The other part of the inequality sign is "less than" because the shading is to the left of the endpoint. Any point in the shaded region is less than 4.5, or it could be equal to 4.5
Put another way: x is either 4.5 or smaller
We write that as
which is read out as "x is less than or equal to 4.5"
Surrounding this in curly braces tells the reader we're dealing with a set of values. The first part "x |" means "x such that"
All together we end up with the answer
which translates to "x such that x is less than or equal to 4.5"
Answner:
negative

I hope it can help.
Step-by-step explanation:
If the B is the middle of the segment AC,
AC= AB+BC
AC=7+12= 19.

Answer:
see below
Step-by-step explanation:
Part A
Notice that for each increase of 1 in x, there is an increase of 3 in y
There is a correlation between the amount of sunlight and the height of the plant
Part B
The slope in change in y over change in x
m = 3/1 = 3
y= mx+b
y = 3x+b
The y intercept is when x =0 so b = 4
y = 3x+4
Part C
With no sunlight the plant is 4 cm tall. As the plant gets more sunlight, the plant grows at 3 cm per hour of sunlight.
