So it would be 10-2x . X would be the months and it would be -2 because she uses that much per month
Answer:
A. 49
Step-by-step explanation:
The average rate of change for the interval ranging from x = 3 to x = 5 for the given function represented in the table above can be calculated using:

x2 = 5
x1 = 3
f(x2) = f(5) = 125
f(x1) = f(3) = 27
Thus,


Average rate of change = 49
Average rate of change of the given table values representing an exponential function is A. 49.
Answer:
39.5
Step-by-step explanation:
angle ABC=60=(5x+2)+(3x-2)
60=8x
x=7.5
Angle ABD=(5x+2),(sub x=7.5)
=(5*7.5+2)
=39.5
Answer: 
Step-by-step explanation:
Given : Two opposite sides of a rectangle are each of length x.
Let the other adjacent side be y.
The perimeter of the rectangle is 12 units.
Perimeter of rectangle is given by :-

The area of rectangle is given by :-

Hence, the area as a function x = 
5x-6 is equivalent. This is because 2 (x-1) becomes 2x-2, which makes the expression 3x+2x-2-4, which when put all together becomes 5x-6.
