Answer:
2y-2x-2y= - 22x = 0x + 2y = 1
Step-by-step explanation:
<h3>Given</h3>
Two positive numbers x and y such that xy = 192
<h3>Find</h3>
The values that minimize x + 3y
<h3>Solution</h3>
y = 192/x . . . . . solve for y
f(x) = x + 3y
f(x) = x + 3(192/x) . . . . . the function we want to minimize
We can find the x that minimizes of f(x) by setting the derivative of f(x) to zero.
... f'(x) = 1 - 576/x² = 0
... 576 = x² . . . . . . . . . . . . multiply by x², add 576
... √576 = x = 24 . . . . . . . take the square root
... y = 192/24 = 8 . . . . . . . find the value of y using the above equation for y
The first number is 24.
The second number is 8.
The width is the x-value, meaning that the constant has to be divided by the x-value to get the y-value (height), so take (5,20) for example.
The equation would be 20=(x/5). Multiply both sides by 5 to get x by itself. This gives you that x=100. The constant is 100.
Therefore, the answer is C: 100.
I would say B, one because on A it is not NEARLY it IS, and second it is true, lol.
Lets x = number of books read in that month
2x + 40 = 3x +35
3x - 2x = 40 -35
x = 5
answer is H. 5
You got it right
