Answer:

operation is commutative if and only if equal elements appear in all positions that are symmetrically placed relative to the diagonal from upper left to lower right. That is, to check whether an operation deﬁned by a Cayley’s table is commutative, simply draw a diagonal line from upper left to lower right

Answer:

The commutative property of multiplication states that changing the order of the numbers we are multiplying, does not change the product.

What are the new<br> coordinates of (6,-2) with<br> the dilation scale factor of<br> 1/2.

In-s [12.5K]

Answer:

(3, - 1 )

Step-by-step explanation:

Assuming the dilatation is centred at the origin then multiply each coordinate by $\frac{1}{2}$

(6, - 2 ) → (6 × $\frac{1}{2}$ , - 2 × $\frac{1}{2}$ ) → (3, - 1 )

Which of the following is perfect square trinomial. Ive asked 4 times. Please Help. Will give brainlilest

Nutka1998 [239]

Answer:

D

Step-by-step explanation:

a perfect square trinomial is

$a^2x^2\pm2(ab)xy+b^2y^2$

factorized is

$(ax\pm by)^2$

so as you can see option A and B can't be, because they have -49y^2 and it has to be plus

so the other options are C and D

in the trinomial a=4 and b=\pm 7

the roots of a^2 and b^2

$\pm2abxy=\pm2(4)(7)xy\\\\=\pm56xy$

so it's option d with b=-7

$16x^2-56xy+49y^2$
