Step by Step Explanation:
x5−3x4+x2−4+5x4+3x2+2x+1
=x5+−3x4+x2+−4+5x4+3x2+2x+1
Combine Like Terms:
=x5+−3x4+x2+−4+5x4+3x2+2x+1
=(x5)+(−3x4+5x4)+(x2+3x2)+(2x)+(−4+1)
=x5+2x4+4x2+2x+−3
Answer:
x5+2x4+4x2+2x−3
The calculation is incorrect, because the slope is defined as
![m_{AB} = \dfrac{y_A-y_B}{x_A-x_B}](https://tex.z-dn.net/?f=m_%7BAB%7D%20%3D%20%5Cdfrac%7By_A-y_B%7D%7Bx_A-x_B%7D)
So, Emma has inverted numerator and denominator: she has calculated the inverse of the slope.
The correct calculation would be
![\dfrac{300-900}{180-165} = \dfrac{-600}{15} = -40](https://tex.z-dn.net/?f=%20%5Cdfrac%7B300-900%7D%7B180-165%7D%20%3D%20%5Cdfrac%7B-600%7D%7B15%7D%20%3D%20-40)
