To solve this all you have to do is divide 65 by 5. Since 65 divided by 5 is 13, 13 is your answer. So one book would cost $13.

I hope this helps you.

$\bf r\left[ cos\left( \theta \right)+i\ sin\left( \theta \right) \right]\quad 
\begin{cases}
x=rcos(\theta )\\

2\left( -\frac{\sqrt{2}}{2} \right)+i\ 2\left( \frac{\sqrt{2}}{2}\right)\implies -\sqrt{2}+\sqrt{2}\ i$

Question 7 Multiple Choice Worth 1 points)

expeople1 [14]

Answer:

The answer to your question is (3, 0)

Step-by-step explanation:

Data

4x + 2y = 12 Equation l

x - y = 3 Equation ll

Process

To solve this problem use the elimination method

1.- Multiply equation ll by 2

4x + 2y = 12

2x - 2y = 6

6x 0 = 18

2.- Solve for x

6x = 18

x = 18/6

x = 3

3.- Substitute x in equation ll to find y

3 - y = 3

-Solve for y

-y = 3 - 3

y = 0

4.- Write the solution

(3, 0)
