Shivani played a video game with three levels. It took her 30 minutes to beat the first level and 1 hour and 45 minutes to beat

Georgia [21]

Answer:

9:30 am

Step-by-step explanation:

Add 30 minutes + 30 minutes to get 60 minutes, which is one hour.
Add 1 hour to 1 hour and 45 minutes to get 2 hours and 45 minutes.
Subtract 2 hours from 12:15 pm, to get 10:15.
That'll leave you with just 45 minutes left. To make it easier than subtract 45 minutes from 10:15, subtract 15 minutes from 10:15, to end up at 10:00 am.
45 minutes - 15 minutes = 30 minutes, so then you subract 30 minutes from 10:00 am, and you end up at 9:30 am, which is your final answer

Which function represents a proportional relationship? A) f(x) = 3x 4 B) f(x) = 3 4x C) f(x) = 3x 4 + 3 4 D) f(x) = 3 4x + 3 4

densk [106]

Answer: OPTION B

Step-by-step explanation:

The equation of a line that passes through the origin is the following:

$y=mx$

Where "m" is the slope of the line.

By definition, Proportional relationships have the following form:

$y=kx$

Where "k" is the Constant of proportionality.

Then, as you can notice, if you graph a Proportional relationship you will get a line that passes through the origin.

Therefore, based on the explained above, you can conclude that the option that shows a function that represents a Proportional relationship is the Option B.

Then, this is:

$f(x)=\frac{3}{4}x$
