Date;
Do the points (1,4) and (-1, 1) lie on
the 2x²+7y²= 9 ?

(1, 4) no; (-1, 1) yes.

Step-by-step explanation:

For a given ordered pair to lie on the graph of an equation, they must be able to produce a true statement when plugged in. Basically, what I'm saying is when we plug in (1, 4) and (-1, 1) in their respective x- and y-positions, the result must = 9 for them to lie on the graph. So we'll do just that.

First with (1, 4)

2(1)² + 7(4)² = 9

2(1) + 7(16) = 9

2 + 112 = 9

114 ≠ 9

114 is not 9; this is not a true statement, (1, 4) does not lie on the graph of the equation.

Next with (-1, 1)

2(-1)² + 7(1)² = 9

2(1) + 7(1) = 9

2 + 7 = 9

9 = 9

9 does equal 9; this is a true statement, (-1, 1) does lie on the graph of the equation.

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
