Choice B.
how you can determine is to look at the x coordinates. If you see two x coordinates, and they have different corresponding y values, then the set is not a function.
You would set it up: .5/100 = x/490 and then cross multiply .5 time 490 and 100 times x, and end up with: 245=100x. divide by 100, and get 2.45
Answer:
5
Step-by-step explanation:
Replace 20 instead of m
20/4=5
<span>-4(x-2)-5(y+2)+(-3)(8-6b)
= -4x + 8 - 5y - 10 - 24 + 18b
= -4x -5y + 18b - 26
