What is equation ?

A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used. A lot of specialists, such as air traffic controllers, architects, computer programmers, and carpenters, employ equations on a daily basis.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.

46 + 46 + y + y = 180

2y = 180 - 46 - 46

2y = 180 - 92

y = 88 / 2

Step-by-step explanation:

There are two points: one at x1, y1 and the other at x2, y2. A point with an x value of x one plus x .

The number of rotations that a geometry can fit into is determined by its order of rotational symmetry. The degree of rotational symmetry is expressed as 360°A°, where A° is the lowest angle by which a figure may be rotated from its rotated shape to its original shape. 360 degrees The number of rotations a perfect circle can undergo while still preserving its shape is a measure of a shape's degree of rotational symmetry. A full 360° revolution won't look the same until a triangle is placed back in its initial starting position.

Answer:

For the hexagon, the sum of all angles must be equal to 360. So, we have 360 divided by 6 and we have 60 and this is the angle for the hexagon. For the pentagon, again, the sum of all the angles must be equal to 360, so each angle is equal to 360/5 = 72.

The difference between 72 and 60 is equal to y which is 12.

Step-by-step explanation:

The given statement as an expression is y = 7 + 2x

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

A mathematical statement

The mathematical statement is given as

7 points more than twice the number of points scored by the other team

Represent the points with x and y

So, we have the following representation

7 points more than twice x is  y

is equal to implies =

So, we have:

7 points more than twice x = y

more than implies +, twice implies 2 times

This gives

7 + 2 * x = y

Evaluate

7 + 2x = y

Rewrite as

y = 7 + 2x

The question does not require that we solve the expression

So, we leave it at y = 7 + 2x

Hence, the required expression is y = 7 + 2x

What is a segment of a circle?

A circle's arc and chord together define a segment, which is the area within that region. Let's go over what a circle's arc and chord signify once more.

What is a sector of a circle?

The term "Minor Sector" refers to the tiny area of a circle that is removed by two circle radii. The minor sector is a tiny area occupied by two radii.

Here,

We have to find the formula of the minor sector and minor segment.

We concluded that

The formula of the minor sector =  (θ/360°) × π r²

The formula of the minor segment = (θ / 360°) × πr² - (1/2) r² sin θ (OR) r² [πθ/360° - sinθ / 2] if 'θ' is in degrees.

With the help of the given equation, we know that the required slope is (A) 3/8.

In math, the gradient of a line is a number that tells you how steep it is and in which direction it goes in.

The point-slope form is a way of writing equations (y-y₁=m(x-x₁)) to emphasize the slope and a point on the line that isn't the y-intercept.

To highlight the same line's slope and y-intercept, you can rewrite the equation in slope-intercept form (y=mx+b).

So, we have the equation:

-3x + 8y = 12

Calculate the slope as follows:

We need to change it into a more general format.

-3x+8y=12

⇒ 8y = 3x+12

⇒ y = 3x/8+12/8

⇒ y = 3x/8+3/2

If you look at it in terms of y = mx+c, the m would be 3/8.

Therefore, with the help of the given equation, we know that the required slope is (A) 3/8.

So the possible values of (z+1/z) are 6 and 0 for z=5 and z=-1 respectively.

An algebraic expression in mathematics is an expression created using variables, constant algebraic numbers, and algebraic operations. A good example of an algebraic expression is 3x2 2xy + c.

A constant has a fixed value and does not vary over time. For instance, the size of a shoe, a piece of clothing, or any other article of clothing will never alter. x+y = 8 is an algebraic equation, and 8 is a constant that cannot be altered. Variables are concepts that change or fluctuate throughout time.

We can start by multiplying both sides of the equation by (z+1/z) to get:

(z-1/z)(z+1/z) = 6(z+1/z)

This simplifies to:

z^2 - 1 = 6z + 6

We can then solve for z by isolating it on one side of the equation.

z^2 - 6z - 5 = 0

(z-5)(z+1) = 0

So the solutions to this equation are z = 5 and z = -1

Now we can substitute the value of z back into the original expression to find the value of (z+1/z)

For z = 5, (z+1/z) = (5+1/5) = 6

For z = -1, (z+1/z) = (-1+1/(-1)) = 0

So the possible values of (z+1/z) are 6 and 0.

The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same.

A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.

When a point is reflected across the Y-axis, the Y-coordinates remain the same, and the X-coordinates are transformed into their opposite signs.

Therefore, the reflection of the point (x, y) across the Y-axis is (-x, y).

A reflection of a point, a line, in the Y axis reflects the image over the Y axis to create a mirror image. In this way, the Y axis would be called the axis of reflection.

Step-by-step explanation:

First, you make the percent into a decimal

35% - 0.35

Next, you multiply 17 and 0.35

17* 0.35= 5.95

Then, you subtract the discount which is $5.95 from $17

17-5.95= 11.05

So, the answer is $11.05
