Answer:

Step-by-step explanation:

To find the value of the function at x = - 2

Locate x = - 2 on the x- axis then go up vertically until the line is met.

The read the corresponding value of y from the y- axis

x = - 2 ⇒ y = 2 → C

Age of car = 5 years. Original cost = $16,995. The current market value is

kicyunya [14]

Answer:

$11,900

Step-by-step explanation:

First you need to get the percentage for 5 years which is 20%,

you then convert the 20% to a decimal .20

Then do the original value of $15,500*.20=3100

Then subtract 15500-3100=11,900 dollars, is what the car is worth after 5 years.

What are the coordinates of the midpoint of the line segment with endpoints 2,5 and 4,-7

Phoenix [80]

<h3>Answer: (3, -1)</h3>

===============================================

Explanation:

The midpoint formula is $(x_m, y_m) = \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)$

This basically says to add the corresponding coordinates and divide by 2.

The given points (2,5) and (4,-7) have x coordinates of 2 and 4. They add to 2+4 = 6, and then that result cuts in half to 6/2 = 3. The x coordinate of the midpoint is 3.

The y coordinate of the midpoint is y = -1 since adding the y coordinates of the given points leads to 5+(-7) = -2 which cuts in half to -1.

So overall the midpoint is located at (3, -1)
