3 consecutive numbers....x, x + 1 and x + 2
x + x + 1 + x + 2 = 72
3x + 3 = 72
3x = 72 - 3
3x = 69
x = 69/3
x = 23
x + 1 = 23 + 1 = 24
x + 2 = 23 + 2 = 25
so ur numbers are 23,24,25 with 25 being the largest
Replace the range for f(x)
So...
0=4-2x
x=2
4=4-2x
x=0
8=4-2x
x=-2

Answer:
The answer to your question is f = 10.35 in
Step-by-step explanation:
Data
Proportion = 4:9
height 1 = 4.6 in
height 2 = f
Process
1.- Write the proportion

2.- Solve for f



4f = 41.4

f = 10.35 in
The slope is 0, the equation is y=50
When the line is horizontal the slope is 0 and when the line is vertical the slope is undefined.
