Answer:

a)  W(x)  =  2, 000  - 275 x  represents the given situation.

b) The cost of the computer after 6 years is $350.

Step-by-step explanation:

Initial worth of the company = $2,000

Depreciation each year = $275

Let, W(x) represent the worth of the computer in x - th year.

So, according to the question:

a)   W(x)  =  2, 000  - 275 x  represents the given situation.

b)  Solving W(x) for x = 6, we get

    W(6)  =  2,000  - 275(6)  = 2, 000  -  1,650

              = 350

⇒W(6)  = $350

Hence, the cost of the computer after 6 years is $350.

Which best describes how to determine the decimal number that is modeled? 7 of 100 parts have been shaded, and 7 hundredths is w
Elina [12.6K]

Answer:

7 of 100 parts have been shaded, and 7 hundredths is written as 0.07

Step-by-step explanation:

Note that we have a grid of 100 squares and 7 of those squares are shaded. We can represent the shaded portion by saying 7/100 which is equivalent to .07.

With this information, we can say 7 out of 100 is shaded and is representative of 7 hundredths.

Note that each digit after the decimal is a multiple of (1/10). We can express this as (1/10)^n where n is the digit place after the decimal.

In this case, we have 7, two digits after the decimal so it will be equivalent to 7 * (1/10)^2 = 7 * (1/100) = 7/100.

Cheers.

7n - 4 (8n+4) = 159
Romashka [77]

Answer:

n = -7

Step-by-step explanation:

Use distributive property:

7n - 32n - 16 = 159

Combine like terms

-25n - 16 = 159

Add 16 to both sides to isolate variable n

-25n = 175

Divide both sides by -25 to isolate variable n

n = -7

Check your work:

7(-7) - 32(-7) - 16 = 159

-49 + 224 - 16 = 159

159 = 159

Determine whether y varies directly with x. If so, find the constant of variation k and write the equation.
anyanavicka [17]
<span>The correct answer is that y does not vary directly with x.

Explanation<span>:
If y varies directly with x, this means that it would fit the equation y=kx for every point in the set.

For the first point, we would have 11=7k; this would mean that k=11//7.
For the second point, we would have 13=8k; this would mean that k=13/8.

Checking using proportions shows us that 11/7 does not equal 13/8:
cross multiply, and you have 11*8=7*13, or 88=91.

This is not true, so k is not a constant, and y does not vary directly with x.</span></span>
