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

Answer:

B. The Positive Solution

Step-by-step explanation:

Because Time is a positive quantity

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

Which is not very big for a sports complex. I've owned houses with more floor space than that.

Answer:

-14g-84/6

Step-by-step explanation:

multiply the numbers

7/2 (-4-1 · 2/3g)

7/2(-4-2/3g)

combine multiplied terms into a signle fraction

7/2(-4-2/3g)

7/2(-4+-2g/3)

find common denominator

7/2(-4+-2g/3)

7/2(3(-4)/3+-2g/3)

combine fractions with common denominator

7/2(3(-4)/3+-2g/3)

7/2(3(-4)-2g/3)

multiply the numbers

7/2(3(-4)-2g/3)

7/2(-12-2g/3)

rearrange terms

7/2(-12-2g/3)

7/2(-2g-12/3)

combine multiplied terms into a single fraction

7/2 · -2g-12/3

7(-2g-12)/2 · 3

distribute

7(-2g-12)/2 · 3

-14g-84/2 · 3

multiply the numbers

-14-84/2 · 3

-14g-84/6

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:

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.

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
