Answer:

The answer is below

Step-by-step explanation:

The model is not given, but I would attached a model and show you how to solve.

Solution:

An equation is a mathematical statement that makes two expressions to be equal to each other. Models can be used to represent equations through the use of various forms such as tiles model, balance scale model, cups and counter model, and so on.

From the model attached, we can form an equation. The equation is given as:

(5 * x) + (-1 * 9) = (-x * 3) + (1 * 20)

5x  + (-9) = -3x + (20)

5x - 9 = -3x + 20

collecting like terms:

5x + 3x = 20 + 9

Simplifying:

8x = 29

8x/8 = 29 / 8

x = 29 / 8

The formula for the nth squaresquare number is Upper S Subscript n Baseline equals n squaredSn=n2. Use the formula to find the 9
AURORKA [14]

Answer:

9801

Step-by-step explanation:

Given the general term for calculating the nth term of a sequence;

Sn = n²

Where n is the number of terms.

To find the 99th term of the sequence using the nth term of the sequence;

Since we want to get the 99th term, this means that n = 99. Substituting n = 99 into the formula we will have;

S99 = 99²

S99 = 9,801

If point U is reflected across the x = -3, what are the coordinates of its reflection image?
Elena L [17]

The coordinates of U after the reflection are: (-5, -3)

<h3>How to get the coordinates after the reflection?</h3>

By looking at the graph, we can see that the coordinates of point U are:

U = (-1, -3)

And we want to reflect it across the line x = -3.

Notice that because this is a vertical line, the y-component does not change by the reflection. Only changes the x-component, such that the distance between the original coordinates and the final coordinates to the line don't change.

The original x-component is x = -1, the distance to the line is:

d = |-3 - (-1)| = 2 units.

Then the new x-component will also be at 2 units of the line, but in the other direction:

new x-component: x = -3 - 2 = -5

The coordinates of U after the reflection are:

(-5, -3)
