For the inverse variation equation xy=k what is the constant of variation k when x=-3 And y=-2

ELEN [110]

ANSWER

The constant of variation is 6.

EXPLANATION

The inverse variation equation is:

$xy = k$

We want to find the constant of variation, when x=-3 and y=-2.

We substitute the values for x and y to get,

$- 3 \times - 2 = k$

Multiply out the left hand keeping in mind that negative times negative yields a positive result.

This implies that;

$k= 6$

Hence the constant of variation is 6.

vredina [299]

Answer:

$216c^{21}d^{36}$

Step-by-step explanation:

$(3c^2d^4)^3 * (2x^5d^8)^3$

$(3c^2)^3 (d^4)^3 * (2c^5)^3 (d^8)^3$

$27c^6 d^{12} * 8c^{15} d^{24}$

$216c^{21}d^{36}$
