Answer:

Step-by-step explanation:
Let
x -----> the number of minutes
y ----> the balloon's height in feet
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-coordinate of the y-intercept
In this problem we have that
The slope is equal to
----> is negative because is a decreasing function

Remember that the y-intercept is the value of y when the value of x is equal to zero
In this context the y-intercept is the height of the balloon when the time is equal to zero (initial height)
substitute

Answer:

Step-by-step explanation:
You have to solve for the x intercept on the equation

That is the x intercept for that equation.
Then solve for the y intercept on the equation

That is the x intercept for that equation.
Use that to find slope for point slope form

1 is the slope
and slope makes B the y intercept so the equation is

Answer: Numbers of servings: 10 and 13, Liters of punch: 14
Step-by-step explanation:

Answer:
293 seconds
Step-by-step explanation:
60*4=240
240+53=293
1. mucus - a slimy substance produced in the nose and throat to moisten and protect them
2. sterile - free from germs
3. enables - gives ability, power, or means to; makes able
4. specialize - to develop in a special way
5. critical - being important to the outcome of a situation
For #6-10, the word in italics is the one most similar to the first word.
6. scarce | plenty | many | <em>rare</em>
7. critical | <em>important</em> | useful | relaxed
8. sterile | dirty <em>| germ-free</em> | bacteria
9. enables | teaches | makes empty | <em>allows</em>
10. specialize | stretch | <em>adapt</em> | organize
I can't help you with the last one, because that's specific to you. If you have questions on how to work on that one specifically, though, feel free to message me or post a question about it. :)
