3x=4y=12z \Rightarrow x=4z,y=3z
\\ \frac{xy}{x+y} 
\\
\\ \frac{4z3z}{4z+3z}
\\
\\ \frac{12z^2}{7z}  
\\
\\ \frac{12}{7} z

So, I proved that \frac{xy}{x+y} \ne z

Nutka1998 [239]

Answer: 2 1/4 hours

Step-by-step explanation:

If Rafael practices 3/4 of an hour each day for three days he will have had 3/4 of an hour practice after day 1, 1 1/2 hours of practice after day 2 and then 2 1/4 hours of practice after day 3.

3 x 3/4 = 9/4

9/4= 2 1/4

a snowball is rolled down a giant hill. the radius of the snowball grows. every second the radius increases by 0.36 inches. four
Bad White [126]

Based on the fact that the radius of the snowball increases by 0.36 inches every second, the linear function can be found to be y = 0.36x + 1.66

<h3>How to find the linear function?</h3>

The linear function is the function that shows how to change in the rate of the independent variable would affect the rate of change in the dependent variable.

The linear function takes the form:

y = mx + b

y = dependent variable

m = slope or change in radius of snowball

x = seconds

b = y-intercept

Solving for the y-intercept gives:

3.1 = 0.36(4) + b

b = 3.1 - 1.44

= 1.66

The linear function is therefore:

y = 0.36x + 1.66
