The values of x and y are proportional. Determine the constant of proportionality(k)
Studentka2010 [4]
<h3>The constant of proportionality is k = 5</h3>

For direct proportion equations, you divide the y value over its corresponding x value to get the value of k.

For example, the point (x,y) = (2,10) is on the diagonal line. So k = y/x = 10/2 = 5.

Another example: the point (x,y) = (6, 30) is also on the same diagonal line, so k = y/x = 30/6 = 5 is the same result as before.

You can use any point on the diagonal line as long as it is not (0,0). This is because division by zero is not allowed.

side note: the direct proportion equation y = k*x becomes y = 5*x which is the graph of that diagonal line. The slope is m = 5, the y intercept is b = 0. All direct proportion graphs go through the origin as shown in the diagram.

Ahmed is solving the following equation for xxx.
Dennis_Churaev [7]

Answer:

No

Step-by-step explanation:

An extraneous solution is a root of a transformed equation which is not a root of the original equation because it was not included in the domain of the original equation.

Ahmed is solving 2\sqrt[3]{x-7}+11=3 for x.

His steps were:

\begin{aligned}2\sqrt[3]{x-7}&=-8\\  \sqrt[3]{x-7}&=-4\\  \left(\sqrt[3]{x-7}\right)^3&=(-4)^3\\  x-7&=-64 \end{aligned}

Since cube roots <u>do not give two solutions when solved</u>, it is <u>not necessary </u>to check his answers for extraneous solutions.
