The best answer, in my opinion, is ¨you don´t indulge in impulse buying¨
part a
$800+8x=y
800 is the money the store manager makes a week
8 is how much money the manager makes per every hour that is worked extra
x is the amount of extra hours the manager works
y is the amount of money he makes all together
Yes, the inverse of a symmetric matrix is also symmetric.
Take the symmetric matrix A, we have:

and

This gives:

Using the properties:

and

We get:

Since

, we can perform the substitution to get:

Multiplying by

on both sides:



Proving that the inverse of a symmetric matrix is also symmetric.
Answer:
i do not know how to do this yet but it looks like a high school thing
Step-by-step explanation:
Answer:
C) (6 x 3) - 18 ÷ 9
Step-by-step explanation:
I'll solve this question by writing down every step and doing it one by one.
1. Multiply 6 by 3
--> This will be represented as 6 x 3.
2. Subtract the quotient of 18 and 9
--> The quotient is a number resulting in a division of another number. In this case, 18 is bigger than 9, so the quotient will be: 18 ÷ 9.
--> Since we are subtracting this from the equation we got earlier, it can be expressed as (6 x 3) - (18 ÷ 9)
This equation is the same as C) (6 x 3) - 18 ÷ 9, so C is our final answer.
