Answer:
y =-1/4x -8
Step-by-step explanation:
3x+12y=-96
Slope intercept form is y = mx +b where m is the slope and b is the y intercept
Subtract 3x from each side
3x -3x+12y=-3x-96
12y = -3x-96
Divide each side by 12
12y/12 = -3x/12 -96/12
y =-1/4x -8
Answer: length of the drive way = 56 feet
Width of the driveway = 12 feet
Step-by-step explanation:
The rectangular driveway has two equal lengths and two equal widths. The area of the driveway is expressed as
length,l × width,w
The area is 672 feet squared. It means that
L×W = 672
The length of the rectangular driveway is four feet less than five times the width. It means that
L = 5W - 4
Substituting L = 5W - 4 into LW = 672
W(5W - 4) = 672
5W^2 - 4W - 672 = 0
5W^2 + 56W - 60W - 672 = 0
W(5W + 56) - 12(5W + 56) = 0
(W - 12)(5W + 56) = 0
W - 12 = 0 or 5W + 56 = 0
W = 12 or 5W = -56
W= 12 or W = - 56/5
The Width cannot be negative , so
W = 12
LW = 672
12L = 672
L = 672/12 = 56
Answer:
Each pack of chicken costs $8 and each pack of beef costs $9.24.
Step-by-step explanation:
This question can be solved using a system of equations:
I am going to say that:
x is the cost of each pack of chicken.
y is the cost of each pack of beef.
2 packs of chicken and 3 packs of beef for $42.50.
This means that 
5 packs of chicken and 6 packs of beef for $94.25.
This means that 
We have to solve the following system:
I will use the addition method, multiplying the first equation by -2, and adding to the second
-4x + 5x - 6y + 6y = -85 + 94.24
x = 9.24.
And
Each pack of chicken costs $8 and each pack of beef costs $9.24.
Answer:
She must sell $60,000
Step-by-step explanation:
4 percent of 60,000 is 2,400 and you add the $400 that she automatically makes every month and you get $2800 as the total amount she makes.
