Which of the following equations is written in standard form?

Harlamova29_29 [7]

Standard Form is ax + by = c, where a, b, and c are not fractions and a is not negative.

So, you can go through each of your options to see which ones work with those rules.

A. 2.5x + 3y = 12 No, this is not in Standard Form. 2.5 can be rewritten as 2 $\frac{1}{2}$ , menaing A is a fraction, which you can't have.

B. -10x - 3y = 1 No, this is not in Standard Form. A is -10, but A can't be negative.

C. 2x + 3y = 12 Yes, this is in Standard Form. It follows all of the rules.

D. 5x + 5y = 10 Yes, this is in Standard Form. It follows all of the rules.

So, C and D are both written in Standard Form.

Which of the following expressions is correct? Select one: a. marginal cost = (change in quantity of output)/(change in total co

Natasha_Volkova [10]

Answer:

b. average total cost = total cost/quantity of output

Step-by-step explanation:

The marginal cost is the additional cost of producing one more unit of output and it can be calculated by taking the change in total cost and dividing it by the change in quantity, its formula is:

Marginal cost = change in total cost/ change in quantity

The average total cost (sometimes referred to simply as average cost) is total cost divided by the quantity of output, its formula is:

Average total cost = total cost / quantity of output

The total cost is obtained adding together the fixed costs and the variable costs, its formula is:

Total cost = fixed cost + variable cost

The average variable cost is obtained when variable cost is divided by quantity of output, its formula is:

Average variable = variable cost / quantity of output

I hope you find this information useful and interesting! Good luck!
