[tex]\displaystyle\\Answer:\ -\frac{14}{13} x+y=\frac{8}{13}[/tex]

Step-by-step explanation:

Ax+By=C   the slope is 14/13   (5,6)    (-8,-8)

The slope m equil 14/13

[tex]\displaystyle\\By=mx+C\\\\By=\frac{14}{13} x+C\ \ \ \ (1)[/tex]

Substitute the coordinates of the points into equation (1) and obtain a system of equations:

[tex]\displaystyle\\\left \{ {{B(6)=\frac{14}{13}(5)+C } \atop {B(-8)=\frac{14}{13}(-8)+C }} \right.\\\\\left \{ {{6B=\frac{70}{13} +C\ \ \ \ \ \ \ (2)} \atop {-8B=-\frac{112}{13}+C\ \ \ (3) }} \right.[/tex]

Multiply  both parts of the equation (3) by -1:

[tex]\displaystyle\\\left \{ {{6B=\frac{70}{13}+C \ \ \ \ (4)} \atop {8B=\frac{112}{13}-C }} \right.[/tex]

Add these equations :

[tex]14B=\frac{182}{14}\\\\ 14B=14[/tex]

Divide both parts of the equation by 14:

[tex]B=1[/tex]

Hence, let's substitute the value of B into equation (4):

[tex]\displaystyle\\6(1)=\frac{70}{13}+C \\\\6=\frac{70}{13}+C\\6-\frac{70}{13} =\frac{70}{13} +C-\frac{70}{13}\\\\\frac{6*13-70}{13}=C\\\\\frac{78-70}{13}=C\\\\\frac{8}{13}=C\\[/tex]

[tex]\displaystyle\\Thus,\ C=\frac{8}{13}\\\\ So,\ 1(y)=\frac{14}{13} x+\frac{8}{13} \\ -\frac{14}{13} x+y=\frac{8}{13}[/tex]

Hello!

Let's solve:

      [tex]\text{Copy down the equation}\\14+7.2n=11+7.5n\\\\\\\text{Move all the variables to one sides and constants to the other}\\14-11=7.5n-7.2n\\7.5n-7.2n = 14-11\\0.3n = 3\\\\\\\text{Divide both sides by 0.3}\\\dfrac{0.3n}{0.3} =\dfrac{3}{0.3} \\\\n = 10[/tex]

Answer: 10

Hope that helps!

Answer:

[tex]-\frac{16}{21}[/tex]

Step-by-step explanation:

lets organize the equation so it becomes easier to see

[tex]-2\frac{1}{3} + 1\frac{4}{7}[/tex]

switch the spots so that it becomes even easier to read (this does not affect the result in any way)

[tex]1\frac{4}{7}-2\frac{1}{3}[/tex]

now make them both improper fractions

[tex]\frac{11}{7} -\frac{7}{3}[/tex]

and make them both have the same denominator (21)

[tex]\frac{33}{21} -\frac{49}{21}[/tex]

and solve

([tex]33-49= -16[/tex])

[tex]\frac{33}{21} -\frac{49}{21} =\frac{-16}{21}[/tex]

can we simplify [tex]\frac{-16}{21}[/tex]? does 16 and 21 have a common factor?

No.

so our result is

[tex]-\frac{16}{21}[/tex] or 0.761904762

According to the following graph, the equations  y=x+7 and y=x²+4 will intercept 2 times at the points (-1.3, 5.7) and (2.3, 9.3).

Intercept:

The point where the line or curve crosses the axis of the graph is known as intercept.

That is, if a point crosses the x-axis, then it is known as the x-intercept. Similarly, if a point crosses the y-axis, then it is called as the y-intercept.

Given,

Here we have the equation  y=x+7 and y=x²+4.

Now, we need to find the number of times the equation is intercepts.

First, we have to plot the graph for the given equations,

Then based on that one we have easily identify the intercepting points in order to get the results.

In the following graph, the blue line represents the equation y=x²+4 and the red line represents the equation y = x + 7.

While we looking into the graph we have identified that the two lines are intersecting at two point they are (-1.3, 5.7) and (2.3, 9.3).

The solution for the value w is 13 in the equation 8w+8 = 9w-5.

Two rays, referred to as the angle's sides and vertex, come together to form an angle. Angles created by two rays are located in the plane where the rays are located.

Dihedral angles are formed when two planes intersect. The angle formed by the rays lying perpendicular to the two intersecting curves at their point of intersection can also be used to define an angle between two intersecting curves.

Angle is a term used to describe the size of an angle or of a rotation. This metric represents the proportion of a circular arc's length to radius. In the case of a geometric angle, the arc is centred at the vertex and is bound by the sides.

We know that vertical angles of intersection are equal, so here

⇒ (8w+8) = (9w-5)

⇒ 8w+8 = 9w-5

⇒ 9w - 8w = 8 + 5

⇒ w = 13

Angle measure = 8(13)+8

According to the triangle inequality theorem, the measure for the third side can be GE = 6 units, because: A. 3 + 5 > 6, 5 + 6 > 3, and 6 + 3 > 5.

The triangle inequality theorem states that the set of side measurements that will form a triangle will be the set of side lengths whereby the sum of any two sides will be greater than the third side of the triangle.

For example, if a, b, and c are the side lengths of a triangle, then:

Thus, we have the given lengths:

FE = 3 units

FG = 5 units

Therefore, the third side length would be GE = 6 units based on the triangle inequality theorem because:

3 + 5 > 6

5 + 6 > 3

6 + 3 > 5

ANSWER:

A polynomial is an algebraic expression of ordered addition, subtraction, and multiplication made up of variables, constants, and exponents.

Polynomials are made up of finite terms. Each term is an expression that contains one or more of the three elements they are made of variables, constants, or exponents.

In this case, for each term, the variable is x, the constant is 1, and the exponents are 5, 2, and 1, respectively.

This means that we have a sum of monomials, that is, that the expression is a polynomial.

Answer:

a) x+4

b) a = 1, b = 10

Step-by-step explanation:

a) You can read the lenght of AB, which is 4 + x

b) The lenght of AD is 6+x

The area of the rectangle ABCD is lenght AB * lenght CD,

so (4+x)*(6+x) = 24 + 6x + 4x + x^2 = x^2 + 10x +24

Since this must equal 28, it follows that

x^2 + 10x + 24 = 28,

so 1*x^2 + 10x = 4

(note that 1*x^2 is just x^2)

so a = 1 and b = 10

Step-by-step explanation:

The required value of XYZ squared would be 3136 which is determined by substituting x = -2, y = 7, and z = -4.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

We have to evaluate xyz squared if x = -2, y = 7, and z = -4.

⇒ (xyz)²

Substitute the values of x = -2, y = 7, and z = -4 in the above expression

⇒ [(-2) × (7) × (-4)]²

Apply the multiplication operation and we get

⇒ (56)²

⇒ 3136

Therefore, the obtained value of XYZ squared would be 3136 if x = -2, y = 7, and z = -4.

We are asked to find the negative interval of this function.

A negative interval means that where the y values of the function are negative.

Let us have a look at the graph of this function.

As you can see,

For x = 0, the interval is positive.

For x = 1 and x = -1 the y value is 0 (we don't consider 0 as either positive or negative that's why 0 is not included in the negative or positive interval)

The y values of the function are negative for

x > 1 and x < -1

Therefore, the negative interval of the function y = x² + 1 is

An arithmetic progression is a sequence in which each number is a fixed amount larger (or smaller) than the one before it. The common difference is the sum in question.

By picking two consecutive words in the sequence and deducting the first from the second, we may get the common difference for a particular sequence.

The graph of linear function is a straight line. A function with the formula y=f(x)=ax+by=f(x)=ax+b is said to be linear.
