Answer:
Option (c) is correct.
The distance covered by the man in 1 hour is represented by te expression 
miles.
Step-by-step explanation:
Given: A man walks 10 miles in x hours.
We have to choose a correct expression that represents the distance covered by the man in 1 hour.
Consider the given statement."A man walks 10 miles in x hours."
Using UNITARY METHOD,
(is a method in which we first find the value of a single unit and then multiply it with desired quantity)
Distance covered by man in x hours = 10 miles,
So distance covered by man in 1 hour = miles.
So, The distance covered by the man in 1 hour is represented by te expression miles.
Well using elimination is easy because they basically did it for you.
4x-5y=-6
2x+5y=12
The postive 5y and negative 5y cancel out because -5y plus 5y is zero.
so you are left with
4x=-6
2x=12
Add these together
6x=18
divide both sides by 6 and Solve to find your x
x=3
Now we have to eliminate x to find y.
we multiply the second equation by -2 so it can cancel out so
(2x+5y=12)-2
-4x-10y=24
Add the equations together
4x-5y=-6
-4x-10y=24
You are left with -15y = 30
Solve for y
y = -2
So your final answer for the elimination would be
(3,-2)
When we reflect a point across y=x, the x and y coordinates switch out , that is (x,y) becomes (y,x) . SO for point (1,2), on reflection across y=x, (1,2) becomes (2,1) . And when we do reflection across y=-x, (x,y) becomes (-y,-x). Therefore point (2,1) on reflection across y=-x becomes(-1,-2) .
So the final answer is (-1,-2) .
