Answer:
4+7x
Step-by-step explanation:
Full price of popcorn: $3.50
Price of popcorn after half the movie: $1.75
price of drinks: $1.35
The question is....."Determine the cost for purchasing 3 orders of popcorn and 3 drinks when the movie is half over."
$1.75*3=$5.25
$1.35*3=$4.05
the price of the 3 orders of popcorn would be $5.25
The price of the 3 orders of drink would be $4.05
5.25 + 4.05 = $9.30
In total the 3 orders of popcorn and 3 orders of drink would cost $9.30
Hope this helps! :)
Answer:
False
Step-by-step explanation:
Negative and Negative always equals positive
Negative and positive always equal negative
Question 1:
For this case we have an equation of the form:

Where,
- <em>k: inverse variation constant.
</em>
Then, substituting values we have:

From here, we clear the value of k.
We have then:

Answer:
the constant of inverse variation is:

Question 2:
For this case we have:

Where,
- <em>k: constant of variation.
</em>
Then, substituting the value of the constant we have:

We now substitute the value of x:

Answer:
the value of y when x = 4 is:
