Y = 12x is a direct variation which is a proportion.
As x increases y also increases.
You would subtract how many times Dion tagged bill with how many times bill tagged Dion, so 12 - 7 = 5
1). y-3=-2(x+4)
2) slope = 3/4
y+2=3/4(x+4)
y=3/4x +1
3x-4y=4
looks like only the last one
Answer:
80
Step-by-step explanation:
There are four 4 by 3 rectangles, so I did 4x3 and got 12, then multiplied by 4 to get 48. There are also two 4 by 4 squares, so 4x4=16 and 16x2=32
32+48=80
