Answer:

5x +y = 16

Step-by-step explanation:

Given a point and slope, it often works well to start with the point-slope form of the equation for a line:

y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

Your point and slope make this ...

y -6 = -5(x -2)

y -6 = -5x +10 . . . . . . eliminate parentheses

5x +y = 16 . . . . . . . . . add 5x+6 to both sides; your standard form equation

SOVA2 [1]

Answer:

Step-by-step explanation:

This is assuming the following:

1) fork boxes comes with 12 count.

2) spoon boxes comes in 18 count.

3) knife boxes comes in 24 count.

Find the least common factor:

12: 12, 24, 36, 48, 60, 72

18: 18, 36, 54, 72

24: 24, 48, 72

72 is the least common factor shared by all these numbers.

Find two positive integers such that the sum of the first number and four times the second number is 1000, and the product of th

vladimir2022 [97]

Answer:

The two numbers are:

x = 500

y = 125

Step-by-step explanation:

We want to find two numbers x and y, such that:

x + 4*y = 1000

f(x, y) = x*y is maximum.

From the first equation, we can isolate one of the variables to get

x = 1000 - 4y

now we can replace it in f(x, y):

x*y = (1000 - 4*y)*y = 1000*y - 4*y^2

So now we want to maximize the function:

f(y) =- 4*y^2 + 1000*y

where y must be an integer.

Notice that this is a quadratic equation with a negative leading coefficient (so the arms of the graph will open downwards), thus, the maximum will be at the vertex.

Remember that for a general quadratic equation:

y = a*x^2 + bx + c

the x-value of the vertex is:

x = -b/(2*a)

so, in the case of:

f(y) =- 4*y^2 + 1000*y

the y-value of the vertex will be:

y = -1000/(2*-4) = 1000/8 = 125

So we found the value of y.

now we can use the equation:

x = 1000 - 4*y

x = 1000 - 4*125 = 1000 - 500 = 500

x = 500

Then the two numbers are:

x =500

y = 125
