If x + y = 13 and y = 2, then which of the following is true according to the substitution property? Question 1 options: A) x + 2 = 13 B) y = 13 – x C) x = 13 – y D) 2 + y = 13

A.

Step-by-step explanation:

Since y=2, we can place 2 where y is, giving us the equation:

x+2=13

(And as a bonus, to solve this subtract 2 from each side, making x=11.  If you were to graph the answer, you would have the point (11,2))

x+2=13

Step-by-step explanation:I took the test

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
