Two friends, alison and bernard, are
walking along two different roads. the
roads can be represented by the lines with
equations y=-*+ 410 and y=-x-100.
alison is on the first road at the point with
coordinates (0.410) and bernard is at the
point with coordinates (50 -75).
a verify that bernard is on the road with
cquation y=-x-100.
find the coordinates of the point of
intersection of the two roads.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
