vlabodo [156]

Answer:

y= 2 + 0.23x

Step-by-step explanation:

Giving the following information:

A text message plan costs $2 per month plus $0.23 per text.

First, we need to structure the total cost formula:

y= total cost

x= number of text messages

y= 2 + 0.23x

Now, we can calculate the total cost for any number of text:

x= 200

y= 2 + 0.23*200

y= $48

Write the product as a trinomial.

Andru [333]

First we multiply 2r*r and it gives us $2r^{2}$ .

Then -5r, + 20r = 15r

Then -5*10 gives us -50.

So the answer is: $2r^{2}+15r-50$
