Answer: a. $V=900-150x$

b. $900

c. $150

Step-by-step explanation:

Given: The value of laptop decreases $150 each year .It means it is a linear function.

If after 2 years the laptop is worth $600.

Then the original value of laptop= $\$600+\$150+\$150=\$900$

Now, Let V be the value of the laptop x years after it is purchased.

Then $V=900-150x$ will be the required equation .

To find the value of the laptop 5 years after it is purchased, put x=5 in the equation, we get

$V=900-150(5)\\\Rightarrow\ V=900-750\\\Rightarrow\ V=150$

Thus, the value of laptop after 5 years = $150

Find the midpoint M of the line segment joining the points A= (-7, -6) and B= (1,8).

Marrrta [24]

Step-by-step explanation:

Use midpoint formula,

x = -6/2 = -3 , y=2/2 =1

(x,y)=(-3,1)

so , the coordinates of mid point of line segment is M (-3,1)

A right angled triangle has two shorter sides and one is twice as long as the other. The hypotenuse is 25cm long. What are the l

Bas_tet [7]

Answer: x = 14.43

Step-by-step explanation:

The Pythagorean Theorem states the following:

a^2 + b^2 = c^2

Make one side of the triangle x

Make the second side of the triangle 2x

Now, you can plug the values into the equation, right?

x^2 + 2x^2 = 25^2 or 625

3x^2 = 625

Divide each side by 3 and you are left with:

x^2 = 208.33

Now, take the square root of 208.33

x = 14.43

That is the shorter side. The longer side is twice that value: Therefore, 14.43 x 2 = 28.86 14.43 is one side of the triangle. The other is that same value times two. Therefore, the sides of your triangle are: 14.43 Shorter side 28.86 Longer side

Given f(x)=9-2x, find f(10). A.-11 B.11 C.29 D.-29

zaharov [31]

The given function is a linear function that decreases as the value of the

input x increases.

The value of f(10), given f(x) = 9 - 2·x is option A. -11

Reasons:

The given function is f(x) = 9 - 2·x

The output of the function is the value of f(x) for a given input x of the function.

The input value, x is substituted into the function to obtain the output value, f(x).

Given that the input, x = 10

We have;

f(10) = 9 - 2×10 = -11

Therefore, the correct option for f(10) is A. -11
