No, they forgot to switch variable labels after solving for the independent variable...

y=-8x+4

y-4=-8x

(y-4)/-8=x 

Now that you have solved for the independent variable x, you switch the variable labels...

y=(x-4)/-8

f^-1(x)=(x-4)/-8     which should really be rewritten as:

f^-1(x)=(4-x)/8  :P

Which of the following are not polynomials
Hoochie [10]

Answer:

A, C, F.

Step-by-step explanation:

A polynomial consists of an expression that involves only non-negative integer exponents for the variable; in all of your cases, the variable is x.

So, expression A has a square root of x, that is a rational exponent.

Expression C has variables in the denominators, that is negative exponent.

Expression F has variable at the exponent.

4. Break-Even Analysis
DiKsa [7]

Answer:

x = 1178 games

Step-by-step explanation:

Let the number of games = x

Let the total cost = Tc

Let the total revenue = Tr

Given the following data;

Investment = $10,000

Cost of each game = $1.50

Selling cost = $9.99

Total cost, Tc = (Cost of each game * Number of games) + Investment

Tc = 1.50x + 10000

Total revenue, Tr = Selling cost * Number of games

Tr = 9.99x

Breakeven point is when total cost is equal to total revenue;

Tc = Tr

1.50x + 10000 = 9.99x

9.99x - 1.50x = 10000

8.49x = 10000

x = \frac {10000}{8.49}

x = 1177.86 ≈ 1178 games.

<em>Therefore, the number of games that must be sold before the business breaks even is 1178 games. </em>
