(2/5)x=45, multiply both sides by 5, 2x=225, divide both sides by 2, x=225/2 minutes to read the whole book.

Answer:
-18
Step-by-step explanation:
Put -195 as y and solve
-195 = 9x - 33
Add 33 to both sides
-162 = 9x
Divide both sides by 9
-18 = x
Your answer would be B. (-1,5).
In order for the order pairs to be a function. All of the x coordinates must be different from each other, they can't be the same. There can't be any repeats of the x coordinates. But for the y coordinates, it's okay for them to be the same. The reason why you would eliminate (-1,5) is because there are 2 -1 x coordinates, and that would not make the ordered pairs a function. When you remove them, none of the x coordinates are the same anymore, so it would now be a function.
Hope this helps out :)
