27/25 is in the lowest form
No she is not because 1 2/5 is a bigger number than 5/7.
1 2/5 in decimal form is 1.4, and 5/7 in decimal form is .714.
<span>y=-4/x+1 is ambiguous, since it's not immediately clear whether you meant
-4
y = -4/x + 1 or y = ---------
x+1
I'm going to assume that the latter is what you meant.
1. Interchange x and y, obtaining:
-4
x = --------
y+1
2. Solve this for y, obtaining y+1 = -4/x, or xy + x = -4, or
-x - 4
xy = -x-4, or y = ---------
x
-1 -1 4
3. Replace y with f (x): f (x) = -1 - -----
x
This last result has the correct form.</span>
I wrote the domain and range in interval notation, not sure if that’s how you’re asked to do it. This is how I was taught to state the domain/range of a graph.
Answer:
80
Step-by-step explanation:
You have to add all of the numbers together and divide them by how many numbers there are.
95 + 67 + 43 + 115 = 320
320 / 4 = 80
