Answer:
Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.
Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
Step-by-step explanation:
The general formula is y = mx +b.
m = slope.
b = y-intercept of the line
Given the value of p and b in the equation (( p-2b ) / 2 ), the value of m is 20.
<h3>What is the value of m?</h3>
Given that;
- m = ( p-2b ) / 2
- p = 57.4
- b = 8.7
- Value of m = ?
First, we substitute the value of p and b into the equation.
m = ( p-2b ) / 2
m = ( 57.4 - 2(8.7) ) / 2
m = ( 57.4 - 17.4 ) / 2
m = 40 / 2
m = 20
Given the value of p and b in the equation (( p-2b ) / 2 ), the value of m is 20.

Answer:
6 laps.
Step-by-step explanation:
On Monday she runs 2x + 8 miles, where x miles = the length of the trail.
On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so
2x + 8 = 4x + 4
4 = 2x
x = 2 miles which is the length of the trail.
So each day she runs 4(2) + 4 = 12 miles.
So on Saturday she runs 12/ 2 = 6 laps.
It would still be 17.8, unless there are more numbers after the 8.
