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}.

lina2011 [118]

Answer:

<h2>f(x) = 3x + 4</h2>

Step-by-step explanation:

f(x + 1) = 3x - 7

f(x) = f(x + 1 - 1) = 3(x - 1) + 7 = 3x - 3 + 7 = 3x + 4

Check

f(x) = 3x + 4

f(x + 1) = 3(x + 1) + 4 = 3x + 3 + 4 = 3x + 7 CORRECT
