All you have to do is work the problem backwards. So 6 plus 3, which is 9, then 9 divided by 2 which is 4.5.

Okay so what you are trying to do is solve for the X
1. The first thing you have to do is to get rid of -3, so add 3 to -3 to make it 0. But because whatever you do to one side, you have to do to the other side, you have to add 3 to 6 as well.
2. Now you are left with 2X = 9, but in order to get X by itself, you have to divide it both sides by 2. That leaves you with X = 4.5

2X - 3 = 6
Add 3 to both sides
2X = 9
Divide by 2
X = 4.5

The accompanying table shows the value of a car over time that was purchased for

Dafna1 [17]

The value of the car after 11 years is $3137.18

<h3>exponential function</h3>

An exponential function is in the form:

y = abˣ

where a is the initial value of y, b is the factor, y, x are variables.

Let y represent the value of the car in dollars after x years. From the table:

When x = 0, y = 12700, hence:

12700 = ab°
a = 12700

When x = 2, y = 9849, hence:

9849 = 12700b²
b = 0.8806

The exponential function is:

y = 12700(0.8806)ˣ

For 11 years:

y = 12700(0.8806)¹¹ = 3137.18

The value of the car after 11 years is $3137.18

Answer:

All the expressions that have a negative in the radical

(Boxes 2, 3 5, and 6)

Step-by-step explanation:

You can't take the square root of a negative number. When you square a number, the product will always be positive.

Point A(2, 2) and point D(−4, −3) are located on the grid. Which measurement is closest to the distance between point A and poin

Virty [35]

Answer:

B

Step-by-step explanation:

The distance formula is $D=\sqrt{(y_2-y_1)^{2}+(x_2-x_1)^{2}}$

Where $(x_1,y_1)$ is the first coordinate (our case, point A(2,2)) & $(x_2,y_2)$ is the second coordinate (our case, point D(-4,-3))

<em>Plugging these in into the formula gives us:</em>

$D=\sqrt{(y_2-y_1)^{2}+(x_2-x_1)^{2}} \\D=\sqrt{(-3-2)^{2}+(-4-2))^{2}} \\D=\sqrt{(-5)^{2}+(-6)^{2}}\\ D=\sqrt{25+36} \\D=\sqrt{61} \\D=7.81$

Answer choice B is closest.
