A.you get a symmetric matrix.
you can add to a non symmetric matrix a diagonal symmetric matrix and get a symmetric one but not always and i don t know if you can get one by multiplying two non symmetric matrices.
Answer:
Javon is incorrect because he subtracted 5 from the left side of the equation and added 5 to the right side of the equation
Step-by-step explanation:
Javon and Ivy are both given the equation 5-2x-1/3=4, Javon thinks the first step is -2x-1/3=9. Ivy thinks the first step is -2x-1/3=-1. Who is incorrect and why?
Given equation:
5 - 2x -1/3 = 4
Javon solution:
first step
-2x - 1/3 = 9
This is solved by subtracting 5 from the left side of the equation and adding 5 to the right side of the equation
5 - 2x -1/3 = 4
5 - 2x -1/3 - 5 = 4 + 5
-2x - 1/3 = 9
Javon is incorrect
Ivy solution:
first step
-2x -1/3 = -1
This is done by subtracting 5 from both sides of the equation
5 - 2x -1/3 = 4
5 - 2x -1/3 -5 = 4 - 5
-2x - 1/3 = -1
Ivy is correct
Javon is incorrect because he subtracted 5 from the left side of the equation and added 5 to the right side of the equation
4x=3(x-6)-2
distribute
4x = 3x-18 -2
combine like terms
4x =3x-20
subtract 3x from each side
x = -20
Answer:
Step-by-step explanation:
Well, the 1 is in the tens place. Soooo then you add the three and then add a 0, the answer will be 30% (Sorry if that didn't make sense I tried!)
