What is the domain and range of y=-1/4(x)
LenKa [72]

Domain: (-\infty, \infty)

Range: (-\infty, \infty)

Explanation:

The function is y=-\frac{1}{4} x

The domain of a function is the set of all input values for which the function is well defined. Generally, domain consists of all x-values of the function. Hence, the function y=-\frac{1}{4} x is defined in the interval (-\infty, \infty).

The range of a function is the set of output values obtained by substituting the value of x in the function. Hence, the function y=-\frac{1}{4} x is defined in the interval (-\infty, \infty).

3x-y=1;d:{-3,-1,0,4}
Maslowich
First, rearrange the equation so that it is solving for y:
3x - y = 1
     +y   +y
3x = y + 1
-1         -1
3x - 1 = y
Now substitute the domain values you have listed into the 'x' of the equation to get the values for y.
For example:
3(-3) - 1 = y
-9 - 1 = y
y = -10

A compressed air tank carried by scuba divers has a volume of 8.00 L and a pressure of 141 atm at 22.0°C. What is the volume (in
weqwewe [10]

Answer:

Volume of air in the tank =1,044 Liter

Step-by-step explanation:

Given:

Tank volume = 8 Liter

Pressure = 141 atm

Temperature = 22°C = 273° + 20° = 295° K

Find:

Volume of air in the tank = ?

Computation:

\frac{Pressure\times Tank\ volume}{Tempreture} =\frac{Pressure\times Air\ volume}{Tempreture}\\\\\frac{141\times 8}{295} =\frac{1\times Air\ volume}{273.15}\\\\\frac{1,128}{295} =\frac{Air\ volume}{273.15}\\\\Air\ volume=1,044.45

Volume of air in the tank =1,044 Liter
