Hi there
Root=0.5 means x=0.5
Plug in 0.5 for x
(b-5)0.5^2-(b-2)0.5+b=0
(b-5)0.25-(b-2)035+b=0
Simplify
0.75b-2.25=0
b=3
Hope this helps

Step-by-step explanation:
The 25 is the monthly fee, x stands for the number of months and the 75 is the set fee
The 1st, 4th, and 5th answers are correct
Step-by-step explanation:
y=kx
say that y is the original prince and x is the sale price
15=k(10)
15/10=k
3/2=k
you can check with the next problem to check if it is the same
25=k(20)
25/20=k
5/4=k
so you take 5/4-3/2=-1/4 so the constant is -1/4
Hope that helps :)
