270 degrees this because when you count each angle it is 90 degrees then 180 degrees then 270
Proportional:
4/7 and 10/17.5
2/3 and 9/12
18/8 and 9/4
NOT proportional:
3/8 and 6/141
7/5 and 27/50
Answer:
Step-by-step explanation:
1a) the y intercept, or 20
b) from 0 weeks to 1 week the difference is 10
c) its y=mx+b m is the slope(difference) and b is the y-int so y = 10x+20
2a) the y int, is the same as the x(number of games played) being zero, so here it is 25
2b) after 3 games it was a loss of 1.50 !!! IMPORTANT !! after THREE weeks, so its 1.5/3=0.5 amount on card per week
2c) (ref 1c) but with that same formula/equation - we get y=0.5x+25
