You are trying to decide which cell phone plan to purchase. plan a chargeres $40 for a new phone and $20 a month for usage. plan b provides the phone for free, but has a fee of $30 a month for usage.

A because one time fees for a phone upgrade or initial phone are just one time. Look at the monthly fees instead would you rather pay more each month or less each month? If answer is less A is the best choice even though in the beginning you need to pay more.

Plan B is a better phone plan

Step-by-step explanation:

Step 1-

Plan A-

$40+ $20x=y

x- months

y- total

$40 plus $20 per month would give you the total

Plan B-

$30x=y

x- months

y- total

For Plan B you pay $30 a month for the total and the phone is free so you don't add anything to it.

Step 2-

Substitute x for different values to see how much it would cost for the phone plan per month

Plan A-

40+20(1)=60

So for 1 month it is $60

40+20(2)=80

So for 2 months it's $80

Plan B-

30(1)= 30

So for 1 month it would be $30

30(2)=60

So for 2 months it would be $60

Plan B would be the best plan because it is the cheapest and you get a free new phone

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
