The value of the expressions are not equal

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

Substituting the values in the equation , we get

p = -3²

q = ( -3 )²

On simplifying the equations , we get

The slope from points (5, -7) and (6, -4) is 3.

The slope of a line represents the stiffness or direction of a line. It is also defined as the change in the y-coordinate with respect to the x-coordinate.

The slope of a line from the points (x₁, y₁) and (x₂, y₂) is given by

Here we have

Points (5, -7) and (6, -4)

As we slope of the line is [y₂ - y₁]/[x₂ - x₁]  

Take (5, -7) = (x₁, y₁) and (6, -4) = (x₂, y₂)    

Slope from given points = [-4 - (-7) ]/[6 - 5]    

= [-4 + 7) ]/[1]  = 3    

Therefore,

The slope from points (5, -7) and (6, -4) is 3.

Step-by-step explanation:

Let's assume the number of iPads sold by Target as "x".

Then, the number of iPads sold by Best Buy would be 8 times this value, which is 8x.

We are given that the difference in their sales is 490 iPads. So we can set up an equation:

8x - x = 490

Simplifying and solving for x:

7x = 490

x = 70

Therefore, Target sold 70 iPads, and Best Buy sold 8 times as many, or 560 iPads.

Maximum possible income from sales is $2.6

Linear Programming also called linear optimization, is a method to achieve the best outcome(such as maximum profit or lowest cost) in a mathematical model whose requirements are represented by linear relationships. Linear Programming is a special case of mathematical programming (also known as mathematical optimization).

Linear Programming is used in many industries such as energy, telecommunication, transportation and manufacturing.

This linear function or objective function consists of linear equality and inequality constraints.

Answer:

y = -x + 5

Step-by-step explanation:

To find the equation of the line that is perpendicular to the line y = x + 6 and passes through the point (-4, -1), we'll use the slope-point form of the equation of a line. The slope of a line perpendicular to y = x + 6 is -1, which we can find using the negative reciprocal of the slope of y = x + 6. The slope of y = x + 6 is 1. The negative reciprocal of 1 is -1.

So the equation of the line perpendicular to y = x + 6 that passes through the point (-4, -1) is given by:

y - (-1) = -1(x - (-4))

Expanding and simplifying the right-hand side, we get:

y + 1 = -x + 4

y = -x + 5

Find the solution set for the equation below.

3|5 - x| + 2 = 29

Step-by-step explanation:

in geometry it is a plane figure with at least three straight sides and angles, and typically five or more.

The inverse of the equation is f-1(x) = 2/(x - 3)

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

f(x) = (3x + 2)/x

Express as

y = (3x + 2)/x

Swap x and y

This gives

x = (3y + 2)/y

So, we have

xy = 3y + 2

This gives

y(x - 3) = 2

Make y the subject

y = 2/(x - 3)

Hence, the inverse is f-1(x) = 2/(x - 3)

nth term of A.P. is :

aₙ = a₁ + ( n - 1 ) d

Substitute the value we get,

a₂₀ = 200 + ( 20 - 1 ) 50

Two cars, an Audi and a Tesla, travel a 100 mile journey. The fastest car is Audi by 30mph.

While distance and displacement appear to have the same meaning, they actually have very different definitions and implications. Displacement is the measurement of "how far an object is out of place," whereas distance refers to "how much ground an object has covered during its motion."

The formula of the speed is given as:

Speed = distance / time

For Audi:

Speed = 100 / 2 = 50 mph

For Tesla:

Speed = 100 / 5 = 20mph

In terms of geometry, a quadrilateral is a four-sided polygon with four edges and four corners. Its origins are in the Latin terms quadri and latus (meaning "side"). A rectangle is a two-dimensional form with four sides, four vertices, and four corners.

Two main types of concave and convex exist. Convex quadrilaterals also have a number of subclasses, such as trapezoids, parallelograms, rectangles, rhombuses, and squares. A rectangle is a two dimensional shape with four straight sides. Quadrilaterals come in many various shapes, such as parallelograms, trapezoids, rectangles, kites, squares, and rhombuses.

Using probability we know that there is a 43% chance that the 27th person in the line would be a boy.

Probability is simply the possibility that something will happen. When we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several.

The study of events that fit into a probability distribution is known as statistics.

So, we know that:

The boys are 17.

The girls are 22.

Probability formula: P(E) = Favourable events/Total events

Then, the probability that the 27th person is a boy:

P(E) = Favourable events/Total events

P(E) = 17/39

P(E) = 0.43

P(E) = 43%

Therefore, using probability we know that there is a 43% chance that the 27th person in the line would be a boy.

Answer: a - a / (7a/3 - 21b)

Step-by-step explanation:

First, let's simplify the numerator:

Next, we'll simplify the denominator:

7a - 21b = 7a/3 - 7b

Now, we can simplify the entire expression:

(a^2/3b - a) / (7a/3 - 7b) = (3b * a^2/3b - 3b * a) / (7a - 21b * 3) = a - a / (7a/3 - 21b)

We can prove that the statement is false by contradiction, as if a triangle had two obtuse angles, the sum of the measures of the internal angles of the triangle would be greater than 180º.

To prove an statement by contradiction, we must simply take an statement that either accepts the statement (true) or rejects (false).

An angle is classified as obtuse if it has a measure that is greater than 90º.

The sum of the measures of the internal angles of a triangle is of 180º, hence if the triangle had two obtuse angles, then the sum of the measures of the internal angles of the triangle would be greater than 180º.
