Answer:
A triangular bike path
Step-by-step explanation:
bcos by Pythagoras theorem if we do the square of 5 and 12 and that is equal to 13 square. hence this real right angle triangle and others are not.
I really wish I could help you
I don’t understand what the question is,
Could you explain?
Answer:
Step-by-step explanation:
The given system is:
Since I prefer to use smaller numbers I'm going to divide both sides of the first equation by 3 and both sides of the equation equation by 6.
This gives me the system:
We could solve the first equation for and replace the second with that.
Let's do that.
Subtract on both sides:
So we are replacing the second in the second equation with which gives us:
Now recall the first equation we arranged so that was the subject. I'm referring to .
We can now find given that using the equation .
Let's do that.
with :
So the solution is (8,-1).
We can check this point by plugging it into both equations.
If both equations render true for that point, then we have verify the solution.
Let's try it.
with :
is a true equation so the "solution" looks promising still.
with :
is also true so the solution has been verified since both equations render true for that point.
