The inequality  which best represents her purchase is x + y > 12.

Equations and inequalities are both mathematical sentences formed by relating two expressions to each other.

When two expressions are equal, we use the equal sign ( = ). But when we are trying to compare two values or expressions, we use the inequality signs like greater than (>), less than (<), greater than or equal to ( ≥ ) and less than or equal to (≤)  .

If x represents the number of hand soaps and y represents the number of lotions she bought. And Gabriela bought more than 12 bottles of hand soaps and lotions

This means the sum of the bottles of hand soaps and lotions she bought is greater than 12. This can be written as follows:

The number of times of Puerto Rico is 5/6

No earthquake released 10³ of Colombia

From the question, we have the following parameters that can be used in our computation:

The table of values

On the table of values, we have

Colombia = 6.0M

Puerto Rico = 5.0M

This means that

Number of times = Puerto Rico/Colombia

Substitute the known values in the above equation, so, we have the following representation

Number of times = 5/6

Here, we have

Colombia = 6.0M

So, we have

Earthquake = Colombia * 10³

This gives

Earthquake = 6 * 10³

From the table of values, we have no entries with the readings 6 * 10³

The measure of angle ABD of the described Isosceles triangles is; 115°

The parameters are;

Triangle ΔACD is Isosceles triangle

Triangle ΔBCD is Isosceles triangle

m∠BAC = 20°

m∠BDC = 25°

Whereby ΔBCD and ΔACD have their vertex in the same direction, we can have;

AD ≅ AC Given sides legs of triangle ACD

BD ≅  BC Given sides legs of triangle BCD

BA ≅ BA  Reflexive property

Therefore, we can say that;

ΔDAB ≅ ΔCAB  by SSS congruency rule

By the CPCTC (Congruent Parts of Congruent Triangles are Congruent), we can say that;

m∠BAC ≅ m∠BAD

Thus;

m∠BAC ≅ m∠BAD = 20°

Therefore;

m∠BAC + m∠BAD = 20° + 20°

m∠BAC + m∠BAD  = 40°

Thus, m∠DAC = 40°  by the Angle addition postulate

m∠ADC = m∠ACD = (180 - m∠DAC)/2

= (180 - 40)/2 = 70° This is because they are base angles of an isosceles triangle

∴ m∠ADC = m∠ACD = 70°

Similarly;

m∠BDC = 25° = m∠BCD Base angles of isosceles triangle ΔBCD

m∠BCD + m∠DBC + m∠BCD = 180° Sum of the interior angles of a triangle theorem

m∠DBC = 180° - (m∠BCD +  m∠BCD)

= 180° - (25° +  25°)

= 130°

m∠DBC = 130°

m∠ABD ≅ m∠ABC by CPCTC

m∠ABD = m∠ABC

Therefore;

m∠DBC + m∠ABD + m∠ABC = 360° Sum of angles at a point

m∠DBC + 2 × m∠ABD = 360°

130° + (2 × m∠ABD) = 360°

2 × m∠ABD = 360° - 130°

2 × m∠ABD = 230°

m∠ABD = 230°/2

m∠ABD = 115°

Answer: To find the coordinates of the remaining vertices of square ABCD, we can use the information given about diagonal AC and the properties of a square. Since a square has equal side lengths and right angles, we know that the distance between opposite vertices on a diagonal must be equal to the side length of the square.

Given the coordinates of vertex A and C, we can use the distance formula to find the length of AC:

Distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

AC = sqrt((2 - (-2))^2 + (4 - 1)^2)

AC = sqrt(4 + 9) = sqrt(13)

Now that we know the side length of the square, we can use this information to find the coordinates of the remaining vertices. We know that vertex B has the same y-coordinate as vertex A, but the x-coordinate is 2 units to the left of vertex C. Therefore, the coordinates of vertex B are (-2 + 2sqrt(13), 1).

Similarly, we know that vertex D has the same x-coordinate as vertex A, but the y-coordinate is 4 units down from vertex C. Therefore, the coordinates of vertex D are (-2, 1 + 4sqrt(13))

So, the coordinates of the remaining vertices are (2sqrt(13),1) and (-2, 4sqrt(13)) respectively.

The term that must be added to the equation x² - 8x = 9 is 16 and the equation will be ( x - 4 )² = 5²

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The value for x is 10; the perimeter is 56 inches; a possible area the area is 7 square feet (option c); and a possible perimeter is 25 m (option a).

To find the correct value for x, let's replace the possible values and verify if the total is >11.

2x + 9

(2 x 0) + 9 = 0 + 9 = 9

(2 x -5) + 9 = -10 + 9 = 1

(2 x 10) + 9 =20 + 9 = 29

(2 x -8) + 9 = -16 + 9 = 7

Based on this, the correct value for x is 10

The perimeter of an octagon can be calculated using this formula:

8 x lengh of one side

8 x 7 inches =  56 inches

The area of a shape is calculated by multiplying side x side. Due to this, areas are always expressed using square meters, square feet, square kilometers, etc. Based on this principle, a possible area is 7 square feet (option c).

c) h(x) = (8x-24)^(1/3)

A transformation function is a mathematical function used to transform a set of data points from one coordinate system to another. The transformation function takes the form of an equation that expresses a relation between two variables. It is commonly used in sciences such as physics and engineering to convert data from one coordinate system to another.

For example, if one measure the position of an object in Cartesian coordinates (x,y), the transformation function allows one to express the position of the same object in polar coordinates (r,θ). This can be written as: r = sqrt(x2 + y2); θ = arctan(y/x)

To write a new equation from a transformation function, one must first determine the desired coordinate system. Then, one can use the transformation function to find the relation between the two variables in the given coordinate system. For example, if one wants to express the position of an object in Cartesian coordinates from polar coordinates, the equation would take the form: x = r*cos(θ) ;    y = r*sin(θ)

This equation expresses the relation between the two variables in Cartesian coordinates. Then, one can use this equation to determine the position of any object in Cartesian coordinates given its position in polar coordinates.
