Table:
4 cups of water, 5 cups of flour.
9 cups of water, 10 cups of flour.
16 cups of water, 17 cups of flour.
29 cups of water, 30 cups of flour.
Equation:
f-1=w
Independent variable:
F
Dependent variable:
W
The equation you can use is x + 3x = 428 with x as the number of cheeseburgers and 3x the number of hamburgers
you solve for x and get 4x= 428 and x=107
so 321 hamburgers were sold that day.
Answer:
Step-by-step explanation:
Given coordinates are (6,-3) and (-5,-4).
![\sf Slope = \frac{y2-y1}{x2-x1}\\\\Slope = \frac{-4+3}{-5-6} \\\\Slope = \frac{-1}{-11} \\\\Slope = \frac{1}{11} \\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Csf%20Slope%20%3D%20%5Cfrac%7By2-y1%7D%7Bx2-x1%7D%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B-4%2B3%7D%7B-5-6%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B-1%7D%7B-11%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B1%7D%7B11%7D%20%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)

Answer:
29 ft x 58 ft
Step-by-step explanation:
Let x be the length of each side perpendicular to the wall, and y be the length of the side parallel to the wall.
The amount of wire available is:
The area of the region is:
The value of 'x' for which the derivate of the area function is zero will yield the maximum area:
The value of y is:
The dimensions of the region with the largest area are 29 ft x 58 ft.
Multiply the top equation by 6 and and the bottom equation by –5 and then add the equations is the correct answer.
Solution:
Given system of equations:
8x + 5y = –7 – – – – (1)
–7x + 6y = –4 – – – – (2)
Multiply top equation by 6 and and bottom equation by –5
(1) × 6 ⇒ 48x + 30y = –42
(2) × –5 ⇒ 35x – 30y = 20
Now add these two equations, we get
(48x + 30y) + (35x – 30y) = –42 + 20
48x + 35x + 30y – 30y = –42 + 20
83x = –20
The variable y is eliminated.
Therefore Multiply the top equation by 6 and and the bottom equation by –5 and then add the equations is the correct answer.
