The function that could be represented by Rebecca’s graph is f(x) =-2(5/4)^x+3
<h3>How to determine the function that could be represented by Rebecca’s graph? </h3>
The properties are given as:
- The function is decreasing.
- The left end is approaching a constant.
For an exponential function to keep decreasing, one or more the following must be true:
- The rate is less than 1
- The leading factor is negative and the rate is greater than 1
For the left end of an exponential function to approach a constant, the following must be true:
- The leading factor is negative and the rate is greater than 1
The equation that has the above properties is f(x) =-2(5/4)^x+3
Hence, the function that could be represented by Rebecca’s graph is f(x) =-2(5/4)^x+3

2x-3y=1
+2x+3y=2
4x=3 substitute 3/4 for x in the first equation..you get y=2/9.
x=3/4
Answer:
A) -192
B) the difference is 77 ft
Step-by-step explanation:
-3x-8=10
First add 8 to both sides
-3x=18
Then divide both sides by -3
x=-6
x is less than or equal to 12
(Distribute the 3 )
3x+3<39
(Move the 3 to the other side by subtracting)
3x<36
(Divide 3 on both sides)
x<12
