Answer:
The constant of proportionality is always the point (x, k * f (x), where k is the constant of proportionality.
Step-by-step explanation:
Let's take as example a linear function of the form: y = kx.
Where, k is the constant of proportionality.
Therefore, the proportionality constant is the point: (x, kx)
Generically it is always the point: (x, k * f (x)
Where, f (x) is a function proportional to x. The constant of proportionality is always the point (x, k * f (x)), where k is the constant of proportionality.
Hello,
Let's calculate ∠O:
∠O=180-2*56=68+
x=90-68=22°
Answer:
x=0
Step-by-step explanation:
-8x + 2(4x + 2) = 4
Use distributive property to get rid of the parentheses
-8x + 8x + 4 = 4
Add the like terms.
x + 4 = 4
Subtract both sides by four.
x = 0
If you have a fraction, then the denominator (bottom) cannot equal 0, since it is impossible to divide by 0. Take a look at the function below.

If we plugged in 2 for x, we would end up with a denominator of 0, making x = 2 "extraneous."
(you can use this example to answer your question, with the denominator being
x-2...any expression that evaluates to 0 when x = 2 would work)
