The y intercept is the value of y when x=0. Substituting we get
y = 4
Answer: 4
29 = 4 + .75b
subtract 4
25 = .75b
divide .75
b = 33.3333333
b = 33 braids
According to the identity if a+b+c=0
then a3+b3+c3=3abc
a3+b3+c3/abc=3
a2*a/bc*a+b2*b/ca*b+c2*c/ab*c=3
cancel a,b,c in all the fraction then you get
<span>a²/bc+b²/ca+c²/ab=3.
</span>hence proved
