Answer:

y=1.50x+20

20 is the fixed price for each month, so that stays the same. It's the independent variable.

y=1.5x+20 is the equation that represents the total cost, y, for a month in which a member attends x exercise classes

Two or more expressions with an Equal sign is called as Equation.

Given,

A health club has a monthly membership fee of $20 and charges an additional fee of $1.50 for every exercise class attended.

We need to write an equation to represent this.

Total cost per person will be y.

Total cost is sum of membership fee and x be the the number of exercise classes.

y=1.5x+20

y equal to one point five times of x plus twenty.

Hence y=1.5x+20 is the equation that represents the total cost, y, for a month in which a member attends x exercise classes

Step-by-step explanation:

Answer:

The conditions are;

Where the number of paper printed = x (x ∈ Z)

For 0 ≤ x ≤ 2,666, It costs less to own and therefore it is better to buy the ink jet printer

For 2,666 < x ≤ ∞, it costs less to own and therefore it is better to buy the lase jet printer

Step-by-step explanation:

The given parameters are'

The cost of the laser printer = $150

The average cost of each page printed with the laser printer = 1.5 cents

The cost of the inkjet printer = $30

The average cost of each page printed with the inkjet printer = 6 cents

Let 'y', represent the total cost of ownership each printer and let 'x', represent the number of paper printed, we have;

For the laser printer, we have;

[tex]y_{laser \ jet}[/tex] = 150 + 0.015·x

For the ink jet printer, we have;

[tex]y_{ink\ jet}[/tex] = 30 + 0.06·x

Therefore, the initial cost of ownership of the ink jet printer is lesser than the initial cost of ownership of the laser jet printer

However, where the cost, 'y', of the laser jet printer and the ink jet printer are equal, we have;

[tex]y_{laser \ jet}[/tex]  = [tex]y_{ink\ jet}[/tex]

∴ 150 + 0.015·x = 30 + 0.06·x

120 = 0.06·x - 0.015·x = 0.045·x

x = 120/0.045 = 2,666.[tex]\overline 6[/tex]

Therefore, given that the cost of ownership and the number of sheets printed is a straight line relationship, after printing 2,666.[tex]\overline 6[/tex] sheets or when 2,667 sheets are printed, the cost of ownership of the laser jet printer will become lesser than the cost of ownership of the ink jet printer

Therefore, the conditions where each printer is better to buy are;

For printing the number of papers in the range 0 ≤ x ≤ 2,666, the ink jet printer is better to buy

When the number of paper printed, 'x', is in the range, 2,666 < x ≤ ∞, the laser jet printer is better to buy.

We want to see when is better to buy which printer.

Printer 1 is better for 2667 pages or more.

Printer 2 is better for less than 2667 pages.

Printer 1 costs $150 pls 1.5 cents per page, so the cost for x pages is:

C₁(x) = $150 + $0.015*x

Printer 2 costs only $30, but each page costs 6 cents, so we have the cost:

C₂(x) = $30 + $0.06*x

First, we need to find the value of x such that the two costs are equal:

C₁(x) = C₂(x)

$150 + $0.015*x = $30 + $0.06*x

$150 - $30 = $0.06*x -  $0.015*x

$120 = $0.045*x

$120/$0.045 = x = 2,666.67

Rounding to the next whole number we have x = 2,667

Then, if you plan to use less than x = 2,667, you should buy the second printer because it has a smaller y-intercept.

If you plan to use 2,667 or more, you should buy the first printer, because it has a smaller slope.

Answer:

C

Step-by-step explanation:

The reason it is C because if the answer was A, then the 55 would have to have been the T since the T represents time in weeks. If it was B, look at explanation for A. It is basically the same reason why. It is not D because if he already the 55 dollars in his savings then the 55 would have been the B of the equation which right now is 120. By process of elimination, your answer should be C. Also the fact that Norman was depositing 55 dollars EACH week is a big help.

Answer

5,600,000

Explanation

In 652 minutes, the bacteria will double 4 times.

163×4=652.

The starting population is 350,000.

After 163 minutes, the bacteria doubles once.

350,000×2 = 700,000

After another 163 minutes, the bacteria doubles again.

700,000×2 = 1,400,000

After another 163 minutes, the bacteria doubles again.

1,400,000×2 = 2,800,000

And finally, when 652 minutes past in total, the bacteria will be at 5,600,000.

2,800,000×2 = 5,600,000

So the population of the bacteria after 652 minutes will be 5,600,000.

Also, if you wanted to write an expression for this, it would be...

350,000×2^4

350,000 is multiplied by 2, 4 times.

Either way, you would get 5,600,000.
