How do you write the domain of a log function?.

The linear equation that gives the rule for this table is y = 19x - 12.

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The standard linear equation can be represented as:

y = mx + b

where, m is the slope and b is the y-intercept of the line.

From the table we can see the two points through which the point passes is:

(x1, y1) = (2, 26)

(x2, y2) = (3, 45)

The slope of the line is given by:

m = (y2 - y1) / (x2 - x1)

m = (45 - 26) / (3 - 2)

m = 19 / 1 = 19

The slope m = 19.

The point-slope form of the line can be written as:

y - y1 = m (x - x1)

y - 26 = 19 (x - 2)

y - 26 = 19x - 38

y = 19x - 38 + 26

y = 19x - 12

Hence, the linear equation that gives the rule for this table is y = 19x - 12.

The statements that are true about the reflectional symmetry of a regular heptagon are:

A heptagon is a type of shape.

A two-dimensional shape having seven sides and seven angles is called a heptagon. It is a member of the two-dimensional geometry polygon class. Polygons are closed geometric shapes with only straight edges. In Greek, "hepta" denotes seven, while "gonia" denotes an angle.

A line of symmetry will connect a vertex and a midpoint of an opposite side.

It has 7-fold symmetry.

A regular heptagon has 7-fold symmetry, which means that it can be divided into 7 identical parts by rotating it by 360/7 = 51.43 degrees. Since it has 7 sides, a line of symmetry will connect a vertex and a midpoint of an opposite side.

It has only 1 line of symmetry, and a line of symmetry will not connect 2 vertices or the midpoints of 2 opposite sides.

One example of a function that is its own inverse is the square root function. The square root function takes a number and returns its inverse, which is always negative.

For example, the square root of 4 is equal to -2, and the square root of -3 is equal to 3. This means that you can multiply a number by -1 and then take the square root to get the same number as the original number. This proves that the inverse of a number is always a negative number. The opposite of a square is known as a rectangle. This shows that the square functions as its inverse. Another example of a function that is its own inverse is the exponential function. The exponential function takes two numbers and returns the reciprocal of their product. This means that the exponential function is also its own inverse because the reciprocal of a product is equal to the product of the reciprocals.

One can solve basic algebraic expressions by following these steps.

In grade 6, students typically learn to solve basic algebraic expressions by following these steps:

Identify the variable and the coefficient (number in front of the variable) in the expression.

Use the order of operations (PEMDAS) to simplify any arithmetic within the expression.

Use the distributive property to combine like terms.

Isolate the variable on one side of the equation by using inverse operations (such as adding or subtracting the same value from both sides, or dividing or multiplying both sides by the same non-zero value).

Substitute in a value for the variable to find the numerical value of the expression.

It's good to practice with a lot of examples and check the solutions and ask for help if needed.

Example:

Solve for x: 3x + 2 = 12

variable is x, coefficient is 3

nothing to simplify

nothing to combine

subtract 2 from both sides: 3x = 10

divide both sides by 3: x = 10/3 or 3.3333

x = 3.3333

It's important to note that solving algebraic expressions can become more complex as the student progresses, but the basic steps remain the same.

Thus, One can solve basic algebraic expressions by following these steps.

The slope and y-intercept of y=-9 is 0 and (0,-9).

Linear equations can be written in the form y=mx+b, where:y is a y coordinate on the line m is the slope of the line.A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant.

Change y=9 in the slope-intercept form: y=mx+c, where m is the slope of the line and c is the y-intercept, y=0(x)+(-9),

Comparing the equation y=0(x)+9 with the equation y=mx+c, we get that m=0. It is a horizontal line. The slope = 0.

The formula of a parabola with the vertex at (2,3) and focus at (0,3) is (y - 3)² = 8(x - 2)

The term vertex in math is known as a special point of a mathematical object, and is usually a location where two or more lines or edges meet.

Here we have given the value of a parabola with the vertex at (2,3) and focus at (0,3).

As we all know that the general form of the vertex is written as,

=> (y − k)² = 4a(x − h) for horizontal parabola

Here we have given that Vertex (2,3) and focus (0,3)

Then it can be easily noticed that focus and vertex lie on the same horizontal line y = 3

Which defined that the axis of symmetry is a horizontal line and also here the focus lies to the right of the vertex so the parabola will open up rightward.

Then the vertex equation is written as,

=> a = 2 - 0 = 2

=> (y - 3)² = (4 x 2) (x - 2)

=> (y - 3)² = 8(x - 2)

Finding the value of f(x) =   or y =   that corresponds to a given value of x is the definition of function evaluation.

Simply swap out all instances of x with the value that has been allocated to x to do this. For instance, if f(4) is to be evaluated, then x has been given the value of 4.

Fully factorizing an equation entails putting it in brackets by eliminating the factors with the highest common denominator.

The easiest method of factoring is: Find the terms in the phrase that have the highest common factor. Any bracket should have the highest common factor (HCF) in front of it.
