Answer:

Step-by-step explanation:

We want to solve the following equation for x:

First, let's expand the parenthesis on the right side of the equation using the distributive property

To add the terms with x, we just need to add their coefficients.

Subtracting 5x from both sides of the equation:

Now, if we subtract 7 from both sides, we have

Since this is a first degree polynomial, it has only one solution and this solution is x = - 13.

Step-by-step explanation:

We want to identify how to determine the x-factors for the graph of a function.

On some occasions, the x values for the function will be provided for you to solve for the y values. but on other occasions, the x values are not provided and you have to decide them yourself.

For a linear function, most times, you can pick values within any range of values, e.g from 0 to 5, or 2, 4, 6, 8, 10. Since it is a linear function, it will eventually result in a straight line that contains all other points.

For a quadratic function, the best practice is to pick points around the vertex of the function. The vertex of a function is either the minimum or maximum point of the function.

For example, if the vertex of a quadratic function is (4, 10), the x-coordinate of the vertex is 4. To pick your points, pick points that are some values below 4 and some values above 4, like 2, 3, 4, 5, 6 or 0, 2, 4, 6, 8 That way, you get points that are on either side of the vertex and that will make your plot easier.

Hope that helps!

The equation of a line in slope - intercept form of a line includes the points (0, 3) and (1, 7)is y - 4x - 3 = 0.

A line includes the points (0, 3) and (1, 7).

We need to write its  equation in slope-intercept form

The formula is

y - y₁ = ((y₂ - y₁)/(x₂ - x₁)) (x - x₁)

y - 3 = ((7 - 3)/1 - 0) (x - 0)

y - 3 = (4) x

y - 3 = 4x

y - 4x - 3 = 0

We can put the 5-sided face downwards so that we have a pentagon-prism.

The volume of the figure will be area of base (area of pentagon) x height.

This way, the height of the figure will be 8 cm and we will find the area of the pentagon, below.

Let's find the area of the base first:

The pentagonal base can be broken down into a square (top left), a triangle (top right), and a rectangle (bottom). We find each of the areas.

• Area of Square

Side lengths are 3 cm, so the area will be:

Area = 3 x 3 = 9

• Area of Triangle

Base is 3 cm and height is 4 cm, so the area will be:

Area = (1/2) * base * height

Area = (1/2) * 3 * 4 = 6

• Area of Rectangle

Base is 7 cm and height is 2 cm, so the area will be:

Area = 7 x 2 = 14

Total Area of Pentagon = 9 + 6 + 14 = 29

Now, the Volume of the Composite Figure is:

Volume = Area of Pentagonal Base * Height

Volume = 29 * 8

Volume = 232 cubic centimeters

Volume = 232 cubic centimeters

The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a shape or planar lamina. Area is the total amount of space occupied by a flat (2-D) surface or an object's shape. On a piece of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies. Consider your square as being composed of smaller unit squares.

Here,

Length in inches=26

Width in inches=14

area in inches=26*14

=364 inch²

Now,

1 inch=2.54 cm

area in cm,

=364*2.54*2.54

=2,348.3824 cm²

The equation will be 15+x=60 as the definition of equation says, "A mathematical statement known as an equation is made up of two expressions joined together by the equal sign(=)".

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. In mathematics, an equation is an expression or a statement that consists of two algebraic expressions that have the same value and are separated from one another by the equal symbol. It is an otherwise stated statement that has been mathematically quantified. Expressions that add up to one another make up an equation. A formula is an equation with two or more variables that shows how the variables relate to one another. A line with the equation y=mx+b, where m denotes the slope and b the y-intercept, is an example of a linear equation.

Since QP and QB are equal the triangle PQB the angles:

The last angle can be found by adding all the internal angles and making it equal to 180 degrees.

The angle BQP and the angle AQP are suplementary, this means that their sum is equal to 180 degrees. So we have:

Since the sides AP and PQ are equal, then the angle PAQ is equal to AQP.

To find the last angle on that triangle we can add all the internal angles and make it to 180 degrees.

The angle APC is suplementary with the sum of the angles APQ and BPQ. So we have:

The sides AP and AC are equal, therefore the angles APC and ACP are also equal.

Then we can find the last angle on that triangle.

The angle CAB is equal to the sum of CAP and PAQ. So we have:

Since the sides AB and BC are equal, then the angles ACB and CAB must also be equal. We can find the value of x with this.

The graph of the new function compares with the first one by A it would be shifted down

A graph is a pictorial representation of a function.

A function is a mathematical expression that shows the relationship between two variables.

Since we are given the functions y = x + 2 and If y = x + 2 we’re changed to y = x - 1. We want to determine how the graph of the new function would change compared with the first one.

We proceed with the transformation as follows.

Let

So, we can see that

y₂ = x - 1

= x - 1 + 2 - 2

= x + 2 - 1 - 2

= x + 2 - 3

= y₁ - 3

Since y₂ = y₁ - 3, we see that the second graph is shifted down by 3 units from the first one.
