Answer:
Step-by-step explanation:
The distanced travelled is equal to twice the distance between points A and B. The distance that was walked in meters is:
The perpendicular line would have a slope of 1/3.
Perpendicular lines have opposite and reciprocal slopes.
To do the opposite, take the original slope (-3) and change the sign (3).
To do the reciprocal, take the slope we changed (3) and flip it as a fraction (1/3).
This gives us a new slope of 1/3.
(1) 5x=-2+7y
(2) x-7y=-34
Using the method of substitution:
Isolating x from the equation (2):
(2) x-7y=-34
x-7y+7y=-34+7y
x=7y-34 (3)
Replacing x by 7y-34 in the first equation:
(1) 5x=-2+7y
5(7y-34)=-2+7y
Solving for y:
35y-170=-2+7y
35y-170+170-7y=-2+7y+170-7y
28y=168
28y/28=168/28
y=6
Replacing y by 6 in equation (3)
(3) x=7y-34
x=7(6)-34
x=42-34
x=8
Answer: The solution of the system of equations is: x=8 and y=6

Answer: B.) 3/4
Step-by-step explanation:
I Got B by dividing 7 by 21 and 28 which is 3 and 4 so B is the correct answer.
