Jana and her friend bought 4 hamburgers, 3 orders of fries, and 2 milk shakes for $3 each. They paid for the food with $20. Which part of the equation represents the total cost of their items? Justify your answer. c = $20 - (4h + 3f + 6)
A) $20; They paid $20 for the food.
B) (4h + 3f); Find the total cost by adding the price of 4 hamburgers to the price of 3 fries
C) 4h + 3f + 6; Find the total cost by adding the price of 4 hamburgers to the price of 3 fries to the price of 2 milkshakes.
D) c = 20 - (4h + 3f + 6); Find the total cost by subtracting the price of 4 hamburgers to the price of 3 fries to the price of 2 milkshakes.
Answers
For this case we have the following variables:
h: Cost of each hamburger bought by Jana and her friend
f: Cost of each order of potato chips bought by Jana and her friend
b: Cost of each milkshake
If you bought 4 hamburgers, 3 orders of potatoes and 2 milkshakes, you have a cost of:
It is known that each shake costs $ 3, so$
Substituting we have:
Thus, the total cost is given by:

dist(A,B)=√[(x₂-x₁)²+(y₂-y₁)²].
We have these points: A(0,0) and B(6,3); its distance will be:
dist(A,B)=√[(6-0)²+(3-0)²]
=√(6²+3²)
=√(36+9)
=√45 ≈ 6.71

The mean net worth is $1,000,000, and the median net worth is $87,000,000,000.
After Bill Gates moves into Centerville, the number of people in the town remains the same at 86,999, but the total net worth changes due to his massive wealth.
Mean Net Worth:
To calculate the mean net worth, we divide the total net worth by the number of people. The total net worth is the sum of the net worth of all individuals in Centerville.
Total Net Worth = Net Worth of 86,999 people + Net Worth of Bill Gates
Total Net Worth = 86,999 * 0 + $87,000,000,000 (Bill Gates' net worth)
Mean Net Worth = (Total Net Worth) / (Number of People)
Mean Net Worth = ($87,000,000,000) / (86,999 + 1) [Adding 1 for Bill Gates]
Median Net Worth:
The median net worth is the net worth of the middle person in the sorted list of net worth values. Since we have one extremely wealthy individual (Bill Gates) with a net worth of $87,000,000,000, he becomes the median net worth, as there are an odd number of people in Centerville.
So, after Bill Gates moves into Centerville:
Mean Net Worth = $87,000,000,000 / 87,000 = $1,000,000
Median Net Worth = $87,000,000,000
Therefore, the mean net worth is $1,000,000, and the median net worth is $87,000,000,000.

Answer:
(- 2, 4 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 4 = - 3(x + 2) ← is in point- slope form
with (a, b ) = (- 2, 4 )
