The midpoint of TS is (-1,-3)
The coordinates of M should be (8,18)
Step-by-step explanation:
Answer:
Standard form: ![x^3+3x^2-x-3](https://tex.z-dn.net/?f=x%5E3%2B3x%5E2-x-3)
Leading coefficient: 1
Step-by-step explanation:
![3x^2-x-3+x^3=\\x^3+3x^2-x-3](https://tex.z-dn.net/?f=3x%5E2-x-3%2Bx%5E3%3D%5C%5Cx%5E3%2B3x%5E2-x-3)
The leading coefficient is 1 because the leading term is
.
You would have no problem at all if it said "7 cows minus 2 cows", or "7 books minus 2 books". The THINGS just happen to be m's instead of cows or books.
No, John is incorrect.
