Step-by-step explanation:
Answer:
a = 2
b = 5
Step-by-step explanation:
Given :
(ar^b)^4 = 16r^20 ; a and b are positive integers :
Opening the bracket :
a^4r^4b = 16r^20
a^4 = 16 - - - - - (1)
r^4b = r^20 - - - (2)
a^4 = 16
Take the 4th root of both sides :
(a^4)^(1/4) = 16^1/4
a = 2
From (2)
r^4b = r^20
4b = 20
Divide both sides by 4
4b/4 = 20/4
b = 5
Hence ;
a = 2
b = 5
Orio has 9 more than Ted. Using the equation y=mx+b to find Orios number of comic books, we can plug 2 months to substitute for the variable x.
2(2)+15 becomes 4+15, which is 19.
We know Ted has 10 comics after 2 months from the graph.
19-10= 9. :)
