Answer:

x = 102.4

Step-by-step explanation:

x/8 = 12.8   | * 8

x = 12.8 * 8

x = 102.4

Answer:  x=102.4

Step-by-step explanation:

(x/8)*8=12.8*8

x=102.4

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

Given

Function f(x) , g(x) and h(x)

Find

Order of the function according to average rate of change

Explanation

Average rate of change can be given by

for f(x)

for g(x)

for h(x)

Final Answer

least to greatest = g(x) , f(x) . h(x)

correct option is 2.

Let h be the hours and y the total charge. Then, for Happy Paws, we have

and for Woof Watches, we have

Then, we need to solve these equations.

Solving by elimination method.

If we multiply by -1 the first equation, we have the equivalent system of equations:

If we add both equations, we obtain

because y-y=0. Then, it yields,

If we move -9 to the left hand side as -9, we have

Hence, to find the total cost, we must substitute this values into one of the 2 equations. If we choose the first one, we obtain

Then, the answers are:

The equation is

and, the total cost of the services will be equal at 7.2 hours

Answer:

2.50h+1.20f=8.60

Step-by-step explanation:

Since the total cost of food costs $8.60, add together the costs of however many burgers and however many fries you bought. 2.50 and 1.20 are multiplied by the amount of food you purchase

Answer: x= -3

Step-by-step explanation:

1) Set up the equation with triangle sum

35 + x + 58 + 90 = 180

2) Solve

183 + x = 180

x = -3

2x - 3y = -6

Solve for y:

-3y= -6-2x

y= (-2x-6) /-3

y= 2/3x+2

Slope intercept form:

y= mx+b

Where:

m= slope (2/3)

b= y-intercept (2)

So, to graph the function, we have to draw a line that crosses the y axis at 2, and for every 3 units moved to the right along the x-axis it goes up 2 units along the y-axis.

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

[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]

The equation that can be set up is, 2x° + 3x° + 36.5° + 36.5° + 2x° = 360°.

The value of x is: x = 41.

Angles that are formed around an endpoint but several rays will have a sum of 360 degrees when each of the angles formed around the endpoint is added together.

The diagram shows the angles that are formed by the five rays at a common endpoint. The angles are, 2x°, 3x°, 36.5°, 36.5°, and 2x°.

The sum of all these angles formed will give us 360 degrees. Therefore, the equation that would be created to find the value of x would be written as:

2x° + 3x° + 36.5° + 36.5° + 2x° = 360° [equation set up to find x]

Combine like terms

7x° + 73° = 360°

Subtract 73 from each side

7x° + 73° - 73° = 360° - 73° [subtraction property of equality]

7x = 287

Divide both sides by 7:

7x/7 = 287/7 [division property of equality]

x = 41

We are given the following function

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.

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.

Although not quite the same, arithmetic progressions resemble linear functions.

If the value nn is a full number, then the expression t(n)=2n-4t(n)=2n4 denotes a series, and the graph of this sequence will have distinct points (as shown below).

The expression f(x)=2x-4f(x)=2x4, where xx is any real number, on the other hand, denotes a function, and this function's line graph will be continuous (as shown below).

Step-by-step explanation:

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

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.
