Answer:
D) f(x) = 4(3)^x
Step-by-step explanation:
Plug y in for f(x) and plug in the points so if they are both true in one equation then it is correct.
A)
y = 3(4)^x
36 = 3(4)^2
36 = 3(16)
This is already incorrect
B)
y = 4(3)^-x
36 = 4(3)^-2
36 = 4(1/16)
36 ≠ 1/4
This is incorrect
I'm going to skip C because I believe D is correct:
D)
y = 4(3)^x
36 = 4(3)^2
36 = 4(9)
36 = 36
Now we plug in the other points
y = 4(3)^x
12 = 4(3)^1
12 = 4(3)
12 = 12
It would be the rounded answer of 36.0
The rule is subtracting 86 each time
24ft^2 = 6ft*4ft
each box has 2ft sides, that makes the box 4ft^2
(24ft^2)/(4ft^2) = 6
Karl can haul 6 boxes
Answer:
Step-by-step explanation:
we know that
Betsy can clean a/b of the house in an hour
The whole house (100%) correspond to the number 1
so
using proportion
Find out how long will it take her to clean the whole house
