Since we always want to have an a which equals 1 so then we don't have to do AC method, a longer process, we're going to want to take out the -1.

-1(x^2 - x - 42)

Then, we want to know what two number multiply to equal c (-42 here) and add up to equal b (-1 here). Those two numbers would be -7 and 6 since -7(6) = -42 and -7 + 6= -1.

So then from here we can just plop these numbers into (x+ __).

1(x-7)(x+6)

This is your final answer, A.

Answer:

h(u)=-7/6u

Step-by-step explanation:

To write a formula for v in terms of u, you need to first isolate v.

4u+8v=-3u+2v

Add 3u to both sides:

7u+8v=2v

Subtract 8v from both sides:

7u=-6v

Divide both sides by -6:

v=-7/6u

Hope this helps!

Answer:

Gross profit formula= 3x

x= number of units sold

Step-by-step explanation:

Giving the following information:

Unitary variable cost= $2

Selling price per unit= $5

<u>To calculate the profit earned, we need to use the unitary contribution margin formula</u>. The contribution margin is a product's price minus all associated variable costs (sales- variable costs), resulting in the incremental profit earned for each unit sold.

Unitary contribution margin= 5 - 2 = 3

<u>Now, the profit formula:</u>

Gross profit formula= number of units*unitary contribution margin

Gross profit formula= 3x

x= number of units sold
