For function f(x)= -4x²-4x-1,   f(x+h)= -4x² - 8xh - 4h² - 4x - 4h - 1, (f(x+h) - f(x))/h= -8x - 4h - 4

The input values of a function are called the domain, and the output values are called the range. The domain can be any set of values, but each input value must have a unique corresponding output value. If there are multiple input values that produce the same output value, the function is not considered to be well-defined. Functions are used to model a wide range of phenomena in many different fields, including science, engineering, and economics. They are also used in calculus to study rates of change and slopes of curves.

To find f(x+h), we need to replace x with (x+h) in the given function:

f(x+h) = -4(x+h)² - 4(x+h) - 1

= -4(x² + 2xh + h²) - 4x - 4h - 1

= -4x² - 8xh - 4h² - 4x - 4h - 1

To find (f(x+h) - f(x))/h, we first need to find f(x):

f(x) = -4x² - 4x - 1

Then we can substitute f(x+h) and f(x) in the formula:

(f(x+h) - f(x))/h = (-4x² - 8xh - 4h² - 4x - 4h - 1 - (-4x² - 4x - 1))/h

= (-4x² - 8xh - 4h² - 4x - 4h - 1 + 4x^2 + 4x + 1)/h

= (-8xh - 4h² - 4h)/h

= -8x - 4h - 4

So, f(x+h) = -4x² - 8xh - 4h² - 4x - 4h - 1, and (f(x+h) - f(x))/h = -8x - 4h - 4.

Step-by-step explanation:

So how I would think the equation would be would be 108 + x = 173. So how I would solve this is subtracting 108 from both sides to get x = 65. There is most likely a different way to set this up but thats what comes to mind with me.

For the mapping diagram 1, we have that the domain and the range are given as follows:

It does not represent a function, as the input of 10 is mapped to different outputs.

For the mapping diagram 2, we have that the domain and the range are given as follows:

It represents a function, as each value of the input is mapped to a single output.

The answer of the given question based on the  length in each isosceles right triangle is given below,

An isosceles right triangle is right triangle in which two legs have the same length, making it isosceles triangle, and one of angles is right angle, making it right triangle.  an isosceles right triangle,  two acute angles are congruent, each measuring 45 degrees, and  hypotenuse is equal in length to legs multiplied by √2.

The isosceles right triangle is special case of  45-45-90 triangle, where  angles measure 45 degrees, 45 degrees, and 90 degrees, respectively. In  45-45-90 triangle, the hypotenuse is equal in length to  legs multiplied by √2.

a. If the hypotenuse is 102√, then each leg is the same length as the hypotenuse divided by √2. Therefore:

Leg = 102√/√2 = 102

b. If one leg is 92√, then the hypotenuse is the length of that leg multiplied by √2. Therefore:

Hypotenuse = 92√ * √2 = 92 * 2 = 184.

The slope of the equation is -2/3 and the y-intercept is 14/3.

A y-intercept is the place where a line or curve crosses, or touches, the y-axis the vertical, often darkened line in the center of a graph.

Since, the equation is not clear, let us consider the equation, 2x+3y = 14

The slope intercept form of a line is given by =

y = mx+c, where m is the slope and the c is the y-intercept.

Converting the assumed equation into slope intercept form,

2x+3y = 14

3y = -2x+14

y = -2x/3+14/3

Here we get the slope = -2/3 and y-intercept = 14/3

Hence, the slope of the equation is -2/3 and the y-intercept is 14/3.

The height of the parallelogram is 5.4 units.

What is area ?

In mathematics, the area is the measure of the size of a two-dimensional surface or region, usually expressed in square units, such as square inches or square meters. The area of a flat shape or planar figure is the amount of space inside its boundary, or the surface of the object, that is covered by a two-dimensional geometric shape.

One way to find the height is to draw a perpendicular line from point B to line segment AD, forming a right triangle. Let's call the length of this perpendicular line h.

Now we can see that the base of the parallelogram is 10 units (from A to D), and the height is h units (from B to the perpendicular line we drew). The area of the parallelogram is given as 54 units², so we can set up the following equation:

Area = base x height

54 = 10h

Solving for h, we get:

h = 54/10 = 5.4

Therefore,  the height of the parallelogram is 5.4 units.

We may build equations that link unknown values in a problem and describe those numbers using variables. We may modify these equations algebraically to get solutions for the unknowable numbers by employing variables. As a result, issue solving is more effective and we can come up with generic answers that may be used in a variety of situations. Moreover, employing variables enables us to see patterns and trends as well as better grasp the connections between various amounts in a situation.

Given that,

Ryan sent 7 fewer messages than Martina.

R = M - 7

Keith sent 2 times as many messages as Martina.

K = 2M

Martina, Ryan, and Keith sent a total of 77 text messages.

M + R + K = 77

Substitute the value of equation 1 and 2 in equation 3:

As a result, the total quilt's area is 512/9 square inches.

Square offers businesses a range of goods and services to help them complete sales deals, use marketing strategies, and control their finances, inventory, and workforce.

The quilt has an 8 x 8 array of square patches, which means it has a total of 8 x 8 = 64 square patches. Each square patch is 2 2/3 inches long.

To find the area of the whole quilt, we need to find the total area covered by all 64 square patches. We can do this by multiplying the length and width of one square patch by the total number of patches:

Area of one square patch = length x width = (2 2/3 in) x (2 2/3 in) = (8/3 in) x (8/3 in) = 64/9 sq in

Total area of all 64 square patches = (64 patches) x (64/9 sq in per patch) = 512/9 sq in

The equation [tex]\sqrt{x} +\sqrt{8}=\sqrt{x+8}[/tex] is an example of the square root property. The square root property states that for any real number a, b, and c, if and only if a + b = c. This property can be used to simplify and solve equations involving square roots.

What does square root mean?

The square root of a number is the number that, when multiplied by itself, produces the original number. For instance, the square root of 16 is 4, because 4 multiplied by itself (4 x 4) equals 16.

The equation [tex]\sqrt{x} +\sqrt{8}=\sqrt{x+8}[/tex] is true because it satisfies the square root property. To see this, note that [tex]\sqrt{x} +\sqrt{8}=\sqrt{x+8}[/tex] implies that x+8=x+8, which is true. Therefore, the equation is true.

To solve for x, we will use the square root property. We know that [tex]\sqrt{x} +\sqrt{8}=\sqrt{x+8}[/tex], so we can rewrite the equation as [tex]\sqrt{x} +\sqrt{8}-\sqrt{x+8}=0[/tex]. We can then use the square root property to simplify the equation to [tex]\sqrt{x} -\sqrt{x}=0[/tex], which implies that x=0.

Answer:

Step-by-step explanation:

To subtract two fractions, we need a common denominator. The smallest number that 6 and 5 both divide into is 30.

Converting the fractions to have 30 as the denominator, we get:

5/6 = 25/30

2/5 = 12/30

x = 5 - [tex]\sqrt{7}[/tex]

Step-by-step explanation:

The given quadratic equation is:

x^2 - 10x + 18 = 0

We can solve this equation using the quadratic formula, which states that for a quadratic equation of the form ax^2 + bx + c = 0, the solutions for x are given by:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 1, b = -10, and c = 18. Substituting these values into the quadratic formula, we get:

x = (-(-10) ± sqrt((-10)^2 - 4(1)(18))) / 2(1)

Simplifying the expression inside the square root, we get:

x = (10 ± sqrt(100 - 72)) / 2

x = (10 ± sqrt(28)) / 2

x = (10 ± 2sqrt(7)) / 2
