First, you'd get x-2y=5 into y=mx+b form. Which would be done like this:
-2y=-x+5 (subtract x in order to get it to the other side
-2y/-2=-x/-2+5/-2 (Divide everything by -2 in order to isolate y)
y=1/2x+-5/2
Once you're done with that, you just have to replace the y-intercept, and find the negative reciprocal of our slope (1/2), which would be -2
This then makes your answer
y=-2x-2
Question:
Solve for x:
. Fill in both values for x below. Write the greater value for x in the first column.
Answer:
and
are the values for x.
Explanation:
The equation is 
Subtracting both sides by 7,

Dividing both sides by 12,

Now, we shall write the equation by removing modulus by adding plus and minus on the other side of the equation.
or 
Solving the equation
, we get,
or 
Thus, the solutions are
and 
<span>Uphill distance = 1 4/5 = 9/5 = 18/10 km
Downhill Distance = 2 7/10 = 27/10 km
Total Uphill and Downhill = 18/10 + 27/10 = 45/10 = 4.5 km
Hence total level ground = Total race km - (Uphill + Downhill)
=10 - 4.5 = 5.5 km
Hence the answer is 5.5 km.</span>
