Answer:

See below

Step-by-step explanation:

<em>Refer to attached</em>

<u>Using two of the points to determine the function:</u>

  • (20, 800), (40, 1600)

<u>Function is:</u>

  • y = mx + b

<u>Finding m and b:</u>

  • m = (1600 - 800)/(40-20) = 800/20 = 40
  • 800 = 40*20 + b
  • b = 0

<u>So the function is:</u>

  • y = 40x

<u>For x = 50, we get</u>

  • y = 40*50 = 2000

Answer:

$ 2000

Step-by-step explanation:

Find the equation. You find the gradient by using the gradient formula (rise/run)

that would be

1600 - 800 over 40 - 20

800/20

m (gradient) = 40

Hence 40x ...

Factor completely.

Factor the polynomial:

4u² – 20u + 25

Rewrite – 20u as – 10u – 10u, and then factor it by grouping:

= 4u² – 10u – 10u + 25

= 2u * (2u – 5) – 5 * (2u – 5)

= (2u – 5) * (2u – 5)

= (2u – 5)² <––– this is the answer.

I hope this helps. =)

What is this simplified? Please help

Answer:

The end result is -1/(x + 1)

Step-by-step explanation:

In order to find the answer to this, we first need to factor the denominator. Since it is a quadratic, we try to find number that multiply to the last term (8) and add to the middle term (9). In this case, the numbers 8 and 1 would work. This allows us to use those numbers in parenthesis along with x as a fully factored form.

x^2 + 9x + 8 = (x + 1)(x + 8)

Now that we have this factored we can take the original equation and factor a -1 out of the top.

(-1)(x + 8)/(x + 1)(x + 8)

Since there is an (x + 8) on the top and bottom, we can cancel those.

-1/(x + 1)
