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)
If given the equation, you need to take the number beside the x and y and change their signs to get your point:
x - 8 (Take the -8 and make it +8)
y + 2 (Take the +2 and make it -2)
Your point is (8, -2)

Answer:
Step-by-step explanation:
2(5)(-5)-(5)^2
=−75
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!
