Step-by-step explanation:
answer ; ( x - 2)( x + 7 )
Since the problem is given all the total walking distance, the first thing we are going to do is find the total distance in the map:


Now that we have the distance in the map, we can establish a ratio between the walking distance and the distance in the map:

We can conclude that each inch the map represents 0.5 miles of walking distance.
Answer: E. 40
Step-by-step explanation:
The x-intercept of a line is when the y coordinate is equal to zero, so input zero in for y and solve for x to find the x-intercept.
1/2x + 3/5(0) = 20
1/2x = 20
x = 40
