Three of those statements are true.
The only one that is NOT correct is:

D.) 15/6
- 3 times 52 = 156, and since you can't exactly convert it to a fraction then i'm assuming that it is 'D'.

Step-by-step explanation:
a-b
a=1/4
b= -2,15 -215/100 semplification -43/20
1/4-(-43/20)
1/4+43/20 minimum comune multiple
5+43/20=
48/20=12/5
Hello from MrBillDoesMath!
Answer:
Leftmost graph: x<= -2 or ( minus infinity, -2]
Middle graph: (-5, infinity)
Right graph: (-2, 3)

n the graphs the white circle means that value is NOT included in the set. For example, In the Right graph the values -2 and +3 (the "endpoints") are NOT included in the solution set.
In graphs ")" means the value is NOT included but "]" (the square bracket) means the value IS included.

P.S. I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!
Let us convert this equation from standard to slope intercept form first.
5x+4y=8
4y=-5x+8
y=-5/4x+2
For the other line to be perpendicular it has to have an opposite reciprocal slope. That would be 4/5. This will make the equation for the new line "y=4/5x+b". We just need to find the y-intercept. Using the point given...
5=4/5(10)+b
5=8+b
b=-3
Answer: y=4/5x-3
