Y=2/3x -4 . First, you look for the y when x=0. Then you try to find the best variation
Answer:
For maximum area, all of the wire should be used to construct the square.
The minimum total area is obtained when length of the wire is 10m
Step-by-step explanation:
For maximum, we use the whole length
For minimum,
supposed the x length was used for the square,
the length of the side of the square = x/4m
Area = 
For the equilateral triangle, the length of the side = 
Area = 
Total Area = + 
, therefore it is minimum
x = 10.00m
150 lower level
200 upper level
Let x = lower level and y = upper level. You can then set up an equation for cost as:
35x + 25y = 10,250
and the equation for total tickets as:
x + y = 350.
Solve using any method.
<span>The original cost of the camera is $120.
Explanation:
6%=6/100=0.06. This means to find 6% tax on a sale, we multiply the amount of the sale by 0.06; this gives us 0.06x, since we don't know the cost of the camera.
We know the amount of tax is $7.20, so we have the equation 0.06x=7.20.
Divide both sides by 0.06:
0.06x/0.06 = 7.20/0.06
x=120.</span>
