The equation of line is y = 2x + 8 and the slope of the line is m = 2

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

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

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the point be represented as P ( -2 , 4 )

y = 2x + 7   be equation (1)

On simplifying the equation , we get

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

So , the slope of the line is m = 2

Since , the lines are parallel the slopes of the lines will be equal

So , m = 2

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 4 = 2 ( x - ( -2 ) )

On simplifying the equation , we get

y - 4 = 2 ( x + 2 )

y - 4 = 2x + 4

Adding 4 on both sides of the equation , we get

y = 2x + 8

Hence , the equation of line is y = 2x + 8

The domain of a logarithm function is the set of all input values (x) for which the logarithm function is defined.

For the natural logarithm function, ln(x), the domain is all positive real numbers, x > 0. This is because the natural logarithm function is defined for input values greater than zero, as the logarithm of any non-positive number is not a real number.

For a logarithm function with a base other than e, such as log_a(x) or logb(x), the domain is also all positive real numbers x > 0. This is because the logarithm function is only defined for input values greater than zero for the same reason as the natural logarithm function.

After addition, 3/5 + 2/7 can be expressed as a fraction as 31/35.

Math is not complete without fractions. The same fundamental procedures that may be applied to integers also apply to fractions. To solve the given problem, we need to add the given fractions using the common denominator property of fractions.

The Least Common Multiple (LCM) of 5 and 7 is 35. Hence, the common denominator is 35.

So, 3/5 + 2/7 = (3 × 7) / (5 × 7)  + (2 × 5) / (7 × 5)

The 5th equivalent fraction to 1/5 is 5/25.

An equivalent fraction is a fraction that has the same value as another fraction, but a different numerator and denominator. There are an infinite number of equivalent fractions for any given fraction. To find the 5th equivalent fraction to 1/5, you can use the fact that equivalent fractions have a common multiple as a denominator.

The first step is to find a common multiple of the denominators of the fractions you want to compare. In this case, the denominator of the first fraction is 5, and you are looking for the 5th multiple of 5, which is 5*5 = 25.

The next step is to find the numerator that corresponds to the common denominator found in step 1. To do this, you can use the concept of cross-multiplication: the product of the original denominator and the new numerator is equal to the product of the original numerator and the new denominator.

1/5 * 5/5 = 1 * 5/5 * 5 = 5/25

Therefore, the 5th equivalent fraction to 1/5 is 5/25.

Factors are numbers that can be divided into a larger number without leaving a remainder.

Factors are used in mathematics to simplify or evaluate expressions and to find common denominators in fractions.

16 is an odd number of factors because it is a square number.

A square number is a number that can be written as the product of an integer multiplied by itself.

For example, 16 can be written as 4 x 4. Every square number has an odd number of factors because it has one more factor than its square root, which is an integer (e.g 4 in this case). So, 4 x 4 = 16 has 5 factors (1, 4, 2, 8, 16) which is an odd number.

Yes, you can stop checking for factor pairs when you find a pair that repeats. This is because when you find a pair that repeats, you have reached the square root of the number, so you have already found all the factors.

A triangle is a three-sided polygon with three angles, each angle is formed by the intersection of two sides of the triangle and these angles are labeled with the corresponding vertex.

There are three angles in a triangle ABC. A triangle is a three-sided polygon and it has three angles. Each angle is formed by the intersection of two sides of the triangle.

In a triangle, the angle between two sides is measured in degrees and these angles are formed by the intersection of the two lines that represent the sides of the triangle. The three angles in a triangle are labeled with the corresponding vertex, for example, angle A, angle B, and angle C.

In a triangle, the sum of the three angles is always 180 degrees. This can be proved using the fact that a straight line is 180 degrees. If we draw a straight line, and divide it into two angles, which are supplementary angles. Therefore, these angles add up to 180 degrees. In a triangle, we can draw one straight line and divide it into three angles, which are supplementary angles, therefore the sum of the angles in a triangle is always 180 degrees.

Therefore, In short, a triangle is a three-sided polygon with three angles, each angle is formed by the intersection of two sides of the triangle and these angles are labeled with the corresponding vertex. The sum of the three angles in a triangle is always 180 degrees.

The gradient of the line y = x - 10 is 1

An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x).

Given the equation of a line is y = x - 10.

The general equation of the line is y = mx + c.

We now get the equation y = x – 10. This will give us the following results when we compare it to the previous line: m = 1 and c = -10.

As a result, the supplied line has a slope of 1.

We must now locate the intercepts. In order to get the y-intercept, let's first enter x = 0 in the equation y = x - 10.

Adding x = 0 to y = x – 10 results in y = – 10.

Therefore, the provided line's y-intercept is equal to -10.

Let's now enter y = 0 to determine the x-intercept in the equation y = x - 10.

By substituting y = 0 for y = x - 10, we obtain x - 10 = 0.

The result of adding 10 from one side to the other is x = 10.

Therefore, the provided line's x-intercept is 10.

Step-by-step explanation:

You want the restrictions on x and the solution to the equation ...

  3/(x+4) +2/(x-4) = 16/((x +4)(x -4))

The denominator factors are (x+4) and (x-4). The values of x that make these zero are -4 and +4, respectively.

The variable may not have values -4 or +4.

In order to avoid extraneous solutions, it often works well to rewrite the equation in the form f(x) = 0. We can subtract 16/((x+4)(x-4)) from both sides to make that happen.

  [tex]\dfrac{3}{x+4}+\dfrac{2}{x-4}-\dfrac{16}{(x+4)(x-4)}=0\\\\\\\dfrac{3(x-4)+2(x+4)-16}{(x+4)(x-4)}=0\\\\\\\dfrac{5x-20}{(x+4)(x-4)}=\dfrac{5(x-4)}{(x+4)(x-4)}=\dfrac{5}{x+4}=0[/tex]

There is no value of x that will make this true. The equation has no solution.

No, 6x and 6xy are not like terms; that is, they are two different terms due to different variables.

Like terms can be defined as terms containing the same variable raised to the same power. Only the numerical coefficients differ. We are the only ones who can combine the same terms in expressions. Combining similar terms shortens and simplifies algebraic expressions to make them easier to work with. Consider example 2xy², 12xy², 7xy²and xy²/2, here also all four terms are like terms because xy ² is the common variable. We have, 6xy and 6x terms. First term 6xy, has a varible xy and in second term 6x, only x is a varible i.e., both varibles are different. Therefore, these terms do not have the same set of variables so they are not like terms. Algebraic expressions can be made simpler by combining like words, which makes advantage of some fundamental real number features.

what is trapezoid?

A trapezoid is a geometric shape with four sides, where two of the sides are parallel to each other, but the other two sides are not. The parallel sides are called the bases of the trapezoid, and the other two sides are called the legs. The height of the trapezoid is the perpendicular distance between the two bases.

The shape in the image is a trapezoid, which has a formula for its area:

Area = (1/2) x (sum of parallel sides) x (distance between parallel sides)

In this case, the parallel sides are 24 units and 25 units, and the distance between them is 10 units (the height of the trapezoid).

Plugging these values into the formula, we get:

Area = (1/2) x (24 + 25) x 10

Area = (1/2) x 49 x 10

Area = 245 units²
