Step-by-step explanation:
So you know the difference is 13. Therefore
x - y = 13
You also know the larger number is 1 less than twice the smaller one. Since 13 is positive, it's safe to assume the first one is larger. So in essence, the larger number (x) is 2 times bigger than the smaller (= 2y...), but one less than that (= 2y - 1)
Therefore
X = 2y - 1
No you can plug in this little expression for x in your original equation:
(2y - 1) - y = 13
And solve for y! Don't forget to distrivute, and to find x, plug the y value you get back into the original (x - y = 13) and solve for x.
Happy calculating! (:

Im pretty sure its C
Step-by-step explanation:
When you put x = 1000 on both C has a much greater value. Even with the negitive 4 on C the function is still greater.
