Answer:
The foot of the ladder is
10
feet away from the base of the wall.
Step-by-step explanation:
This is the number of combinations of 2 from 23
23C2 = 23! / 2! 21!
A quick way to do this is 23*22 / 2 = 253
There's 6.Because there's 2 per mile. So 3x2 =6
Answer:
Point-Slope: 
Slope-Intercept: 
Step-by-step explanation:
The point-slope formula is
. The slope-intercept formula is
. Since we are given the point and slope, we can directly plug it into the point-slope formula.
Point-Slope


To find the slope-intercept form, we can manipulate the point-slope form to get the slope-intercept form.
Slope-Intercept
