Step-by-step explanation: A= A+B/2 h= 50+65/2x30=1725
Answer:
Plan A - 20x+40
Plan B - 30x
Step-by-step explanation:
x will determine the number of months.
For example, Plan A's equation
If I paid for one month, I should get $60.
20(1)+40 = 60
Now for three months, I should get $100. Because Plan A charges $20/month after a one time fee of $40 for the new phone.
20(3)+40 = 100
On the other hand, Plan B gives away a free phone, meaning no one-time fees. It only charges us $30/month. That's easy.
30(1) = $30
30(3) = $90
1st month = $8
2nd Month = $16
3rd Month = $24
4th month = $32
5th Month = $40
6th Month = $48
7th Month = $56
8th Month - $64
After 7 months he only has $56 bucks, not enough to hit $60, but after 8 months he finally has at least $60 (in fact, he has $64)

Step-by-step explanation:
Answer:
A) Vertical.
Step-by-step explanation:
It must pass the vertical line test. That is it must not have any vertical line passing through more than one point on the curve. If it does then it is not a function.
Thus , for example, a circle graph would not be a function.
