Answer:

y=8x+3

Step-by-step explanation:

to check plug the numbers to the equation and you will that it is right

Answer:

f(x) = 8x + 3

Explanation:

I knew f(x) = mx +b is the formula for a linear equation and that when x = 0,

f(x) = b

So, when x = 0 in the table, f(x) = 3 and therefore b = 3

Now we can plug in f(x) = 11 and x =1 into f(x) = mx+b along with our b value

11 = m(1) + 3

solving for m we get m  =  8 which finishes our unknowns

f(x) = mx + b

f(x) = 8x + 3

This process takes advantage of the factoring of the difference of squares:

  a² -b² = (a -b)(a +b)

The method is used to eliminate complex numbers and square roots from denominators.

Answer:

Step-by-step explanation:

the side lengths are (400 - 4x)/2 = 200 - 2x

A = x(200 - 2x)

A = 200x - 2x²

Maximum area will occur when the derivative is set to zero.

dA/dx = 200 - 4x

0 = 200 - 4x

x = 200/4 = 50 ft

each field will be 50 x 33⅓ ft.

total area will be 5000 ft²

Answer:

$0.55

Step-by-step explanation:

1 quarter is 25 cents

2 dimes is a total of 20 cents

2 nickels is a total of 10 cents

if you add all of it up 25+20+10 you get 55 cents but u need it in dollar amount so it would but $0.55 since u have less than a dollar.

Answer:

10, 4, -1

Step-by-step explanation:

10×4=40

40×-1=-40

-40=-40

The three integers could be 8, -5, and 1.

A number without a decimal or fractional element is known as an integer, which can be both positive and negative, including zero.

Given that, the product of three integers is -40.

Since the product is negative, there should be at least one negative number.

The three numbers can be 8, -5, and 1.

8 × (-5) ×1 = -40

Hence, the three integers could be 8, -5, and 1.

Step-by-step explanation:

slope int form: y=1/4x-5

Answer:

y=0.5x-4.5

Step-by-step explanation:

y=mx+b

Use the information provided to find b

0=0.5(4)+b

-2=b

Therefore, the equation goes down to...

y= 0.5x-2

Step-by-step explanation:

using the formula

m = y -y1/ x - x1

0.5 = y -0/x-4 (0.5 = 1/2)

1/2 = y/x -4

2y = x -4

divide both sides by 2

y = 1/2 ( x -4)

y = 1/2x - 2

y -1/2x = -2

Answer:

Step-by-step explanation:

(a) Solving the x-equation for u gives ...

  u = (x -1)/4

Differentiating both equations with respect to u, we have ...

  dy/du = 1 -4u

  dx/du = 4

Then dy/dx is ...

  dy/dx = (dy/du)/(dx/du) = (1 -4u)/4

Substituting for u gives ...

  dy/dx = (1 -4(x -1)/4)/4

  dy/dx = (2 -x)/4

__

(b) The approximate change in y is ...

  ∆y ≈ (dy/dx)(∆x)

For ∆x = 2.98 -3.00 = -0.02, and x=3, the approximate change is ...

  ∆y ≈ (2 -3)/4(-0.02)

  ∆y ≈ 0.005

Answer:

  (x, y, P) = (4/3, 8/3, 112/3)

Step-by-step explanation:

In standard form, the constraints are all "less than or equal to", the variables are all non-negative, and the objective is maximization. This problem is presented in standard form.

  4x +y ≤ 8

  x +4y ≤ 12

  x ≥ 0; y ≥ 0

maximize P = 6x +11y

__

Now we add the slack variables to make the constraints be "equal to". These have a coefficient of +1, and they, too, are non-negative. Here, we'll use s and t as the slack variables.

  4x +y +s = 8

  x +4y +t = 12

These equations, together with the objective function, are combined in a matrix-like "tableau" in which each row is the set of coefficients in one of the equations. Here, the columns represent x, y, s, t, P and the constants. The equation for the objective function is negated so we're trying to minimize that, as well.

  [tex]\begin{array}{ccccc|c}4&1&1&0&0&8\\1&4&0&1&0&12\\-6&-11&0&0&1&0\end{array}[/tex]

Find the column with the most negative value on the bottom row. (Column 2) Divide the rightmost column by this column and find the smallest quotient. Here, the quotients are 8/1 = 8, and 12/4 = 3. The smallest is 3. This identifies the 4 in column 2, row 2 as the "pivot."

Now, row operations are performed to make the pivot be 1 and other values in the pivot column be zero. This gives a new tableau. For example, the new values in row 1 are ...

  4 -1/4, 1 -4/4, 1 -0/4, 0 -1/4, 0 -0/4, 8 -12/4

The new tableau is ...

  [tex]\begin{array}{ccccc|c}15/4&0&1&-1/4&0&5\\1/4&1&0&1/4&0&3\\-13/4&0&0&11/4&1&33\end{array}[/tex]

Now, the most negative number on the bottom row is in column 1, and the smallest quotient of column 6 and column 1 is in row 1. This makes 15/4 the "pivot". After the required row operations, the next tableau is ...

  [tex]\begin{array}{ccccc|c}1&0&4/15&-1/15&0&4/3\\0&1&-1/15&4/15&0&8/3\\0&0&13/15&38/15&1&112/3\end{array}[/tex]

All values in the last row are non-negative, so we are finished. The rightmost column tells us the values of x, y, P that are the solution to the problem

  (x, y, P) = (4/3, 8/3, 112/3)
