If y varies inversely as x, and y = 12 when x = 6, what is K, the variation constant? A. 2 B. 72 C. 144 D. 1/3

Gala2k [10]

In this question, it is given that y varies inversely as x . So the equation is

$y = \frac{k}{x}$

And here k is the proportionality constant .

And when x=6, y=12

$12 = \frac{k}{6}
\\
k =72$

So the values of the proportionality constant k is 72 and the correct option is B.

Given a system of linear equations; explain your strategy for solving the system, show the math required to solve the problem, a

labwork [276]

The solution is (x, y) = (2, 3)

<em><u>Solution:</u></em>

<em><u>Given equations are:</u></em>

y = 3x - 3 ------- eqn 1

y = 2x - 1 ---------- eqn 2

We can solve the equations by substitution method

In eqn 1, we have y equals 3x - 3

If we substitute this in place of y in eqn 2, we can get value of "x"

Substitute eqn 1 in eqn 2

3x - 3 = 2x - 1

Move the variables to one side and constants to other side

3x - 2x = -1 + 3

Substitute x = 2 in eqn 1

y = 3(2) - 3

y = 6 - 3

Thus the solution is (x, y) = (2, 3)
