Mrs. Beatty buys sketchbooks and puzzles. Each sketchbook costs $1 and each puzzle costs $3. Which ordered pair represents the cost of 3 sketchbooks as the

(3,9)

Step-by-step explanation:

The input (x) is the number of sketchbooks purchased, output (y) is the cost.
I see two linear equations.

y= 1x

or

y= 3x

The latter equation illustrates the cost of sketchbooks.

step-by-step explanation:

9-15%

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
