Mathematics

Gala2k [10]2 years ago

a^{-n} =  \frac{1}{ a^{n} }
<em>So,</em> 4-2( 4^{-2})=4-2  \frac{1}{ 4^{2} } = 4-2 \frac{1}{16} = 4- \frac{1}{8}
<em>We amplify 4 with 8 and we get:</em>
\frac{32-1}{8} =  \frac{31}{8}= 3,875

PLEASE HELP QUICK 100 POINTS
MrRissso [65]

Answer:

Change per week: $20

Starting amount of money: $550

Step-by-step explanation:

<u>Given equation</u>:

y=550+20x

where:

  • x = number of weeks
  • y = total account balance

<u>Change per week</u>

As the variable x represents the number of weeks, its coefficient represents the change per week in the amount of money.

Therefore, the change per week in the amount of money in the account is $20.

<u>Initial Balance</u>

The starting amount of money in the account (initial balance) will be the value of y when x = 0:

\implies y=550+20(0)=550

Therefore, the starting amount of money in the account is $550.

Give an example to show that subtraction does not follow the associative rule
Agata [3.3K]

(6 - 2) - 1 = 4 - 1 = 3

6 - (2 - 1) = 6 - 1 = 5

The associative rule doesn't work for subtraction because you get different results when you move the parentheses.
