Answer:
c; 54
Step-by-step explanation:
to find the answer you can first add all the books together
this can be represented by
3 + 2 + 2.5 + 1.5
this answer is 9
then multiply it by 6
9 * 6 = 54
is is c
Answer:
C
Step-by-step explanation:
A function can not have an input that has more than one output.
In the diagram the left is the input and the right is the output. C has the input 2 having an output of -2, -1, 0, 1, and 2. That is more than one.
Answer:
x > - 3
Step-by-step explanation:
x + 2
> -
First turn 2
into an fraction since its easier. So it becomes 
x +
> - 
<u> - </u>
<u> - </u>
<u> </u> Do inverse operations, so subtract
from both sides.
x > -
Combine -
with -
, which gives us - 
x > - 3 Since we know that 6 divided by 2 is 3.
This would not allow me to attach an image so I am going to type a visual representation f what the graph would look like below)
<-------------O--------------------------------------------------->
-5 -4 -3 -2 -1 0 1 2 3 4 5
So, the number line would be a solid line rather than dashed (but I was not able to attach an image so I kind of had to improvise). When using ≥ ≤ sings the circle of the point is closed. When using < and > signs, the circle of the point is open. Thus, in this scenario since he sign is >, then the circle of the point is open. The direction of the arrow and ray for this equality is going to the right because the answer is that x is greater than - 3, Therefore any values greater than - 3 are a possibility which is why the arrow goes on indefinitely.
Answer:
4/b
Step-by-step explanation:
7/b - 3/b
Since the denominators are the same, we can subtract
4/b
Adding a value at the end shifts the graph up that number of units.
The answer is C.
