Answer:
2
Step-by-step explanation:
Pick two points
(2,0) and (3,2)
Then use the slope formula
m= (y2-y1)/(x2-x1)
= (2-0)/(3-2)
= 2/1
=2
Answer:
18500 is the initial value
Every year they increase by a factor of 1.03
Step-by-step explanation:
This is written in the form
y = ab^x where a is the initial value and b is the growth rate/decrease
y = (18500) (1.03)^t
The initial value is 18500
The students will increase by 1.03 - 1 = .03
The factor of increase is what they multiply by which is 1.03

The monthly cost of cell phone is A = 40 + 0.005 m</h3>
Step-by-step explanation:
The monthly fixed charges by mobile company = $40
The cost of sending each text message = 0.05 cents
Now, 100 cents = 1 dollar
⇒ 1 cent =$
⇒ 0.05 cent s =$
Also, the number of text messages send = m
So, the cost of sending m text message = m x ( cost of 1 text )
= m x ( $ 0.0005) = 0.0005 m
Now, Total bill = Fixed rate + cost of m texts
⇒ A =$40 + $ 0.0005 m
Hence, the monthly cost of cell phone is A = 40 + 0.005 m
