Determine if the equation y = 2/5 x − 4 y=25x-4 represents a proportional relationship. If so, determine the constant of proport

Vilka [71]

Answer:

The linear equation represents a proportional relationship and its constant of proportionality is $k = \frac{2}{5}$ .

Step-by-step explanation:

A proportional relationship exists when the following relationship is observed:

$u = k\cdot v$

Where:

$u$ - Dependent variable.

$v$ - Independent variable.

$k$ - Proportionality constant.

If $y =\frac{2}{5}\cdot x - 4$ and $v = x$ and $u = y+4$ , the following expresion is found:

$y = \frac{2}{5}\cdot x -4$

$y + 4 = \frac{2}{5}\cdot x$

$u = \frac{2}{5}\cdot v$

The linear equation represents a proportional relationship and its constant of proportionality is $k = \frac{2}{5}$ .

Angle D has a measure between 0° and 360° and is coterminal with a –920° angle. What is the measure of angle D?

topjm [15]

Take -920/360 = -2.55555
Take the fraction part -0.5555555 * 360 = -200
The positive of that would be 160 degrees
