On both sides of the equal sign you subtract b (-b) which would give you -b+y=2x after that you subtract a y (-y) which gives you -b=2x-y now I was taught that you can't have a negative letter equal something so you change all of the signs to the opposite which would give you b=-2x+y
Spread = highest value - lowest.
Its data set C Spread is 5 - 1 = 4
Answer:
I would say that the answer is 930, if I am mistaken, I am truly sorry
Step-by-step explanation:
I hope this helps tho :) plz mark brainliest
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
