Answer:
x= -136
Step-by-step explanation:
14+x=84
x=70
The team lost 70 games.
84+70=x
154=x
The team played a total of 154 games.
Find the rate of change, (y2-y1)/(x2-x1), from the data given...
(2.16-1.26)/(12-7)=0.18
(1.26-0.72)/(7-4)=0.18
Since the rate is constant, this is a linear equation of the form y=mx+b. Furthermore, since 0 pencils cost 0, b=0, so the cost of the pencils is simply the number of pencils times 18 cents...
c(p)=0.18p (cost with respect to pencils is 0.18 times the number of pencils)
5x - 18 + x = 90
6x = 108
x = 18 degrees
