I'm assuming you mean to list the terms of the expression. Those are mn, -2n, and +8. There are 3 terms there.
Answer:
y = 4
Step-by-step explanation:
An exponential function in standard form is
y = a 
Use ordered pairs from the table to find a and b
Using (0, 4), then
4 = a 
( note that = 1 ), so
a = 4, then
y = 4
Using (1, 8)
8 = 4 
= 4b ( divide both sides by 4 )
b = 2
y = 4 ← represents the values in the table
Answer:
D = 20H
Step-by-step explanation:
The amount Troy (D, in dollars) charges to mow a lawn is proportional to the time (H, in hours) it takes him to mow the lawn.
Hence, we can write D = kH ......... (1), where k is a constant.
Now, given that Troy charges $30 to mow a lawn that took him 1.5 hours to mow.
So, from equation (1) we get
30 = 1.5k
⇒ k = 20.
Therefore, equation (1) becomes D = 20H (Answer)
