Given p(x)= 3x+1 and r(x)= 2x^2+5 which of the following represents the composition p(r(x)) ?
Temka [501]

Step-by-step explanation:

substitute the values

px=3x+1

=(3x+1)/x

=3x/x +1/x

=3+1/x

rx=2x²+5

p(r(x)) =(3+1/x(2x²+5))

=6x²+15+2x²/x+5/x

=3(2x²+5)+1/x(2x²+5)

=(2x²+5)(3+1/x)

An online music store offers 5 downloads for $6.25.Another online music store offers 12 downloads for $17.40.Which store offers
Anon25 [30]
Well, what you have to do is find the unit rate for each one of those prices and how you do that is by dividing each price by the downloads

so $6.25 divided by 5= $1.25

and then $17.40 divided by 12= $1.45


so that means the one with $6.25/5 downloads has a better deal!
