help 8+x2=−12..im confused

Answers

Answer 1

Answer:

Step-by-step explanation:

No real solutions exist. Subtract 8 on both sides to get:

[tex]x^2=-20[/tex]

You cannot take the square root of a negative number without involving imaginary numbers.

Answer 2

Answer and Explanation

__________________________________________________________

-10

__________________________________________________________

The answer is -10 because...

You need to multiply 2 by "x," and to find out what "x" is, we need to add...

[tex]2+-12[/tex]

__________________________________________________________

And if we add  [tex]2[/tex] by [tex]-12[/tex], we get [tex]-10[/tex], which is our answer.

__________________________________________________________

and now, if we add [tex]-20[/tex] by  [tex]8[/tex], we get [tex]-12[/tex], which is what the equation equals, and this is how we know it is correct.

__________________________________________________________

Hope this helps! :)

What point is the solution to the system of equations y = -1/2 and y = 2x - 5?

Step-by-step explanation:

If you were to graph the equations, they intersect at the points 2.25, and -0.5.

Answer:

(9/4, -1/2)

Step-by-step explanation:

We already know the y-coordinate of the solution:  It is y = -1/2.  To find the x-coordinate, we substitute -1/2 for y in y = 2x - 5:

-1/2 = 2x - 5

Clearing out fractions, we multiply all three terms by 2:

-1 = 4x - 10, or

4x = 9

Then x = 9/4

The solution is (9/4, -1/2)

[tex]882 = (x - 3)(2x + 7)[/tex]

values for X?
A. 8< x < 12
B. 4 < x < 20
C. 4 sxs 20
D. 8 sxs 12
SUBMIT

Answers

Answer:

the answer is b

Step-by-step explanation:

The possible inequality for x is 4 < x < 20.

The correct option is (B).

What is inequality?

Inequality, A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to. Either questions or theorems can be used to express inequality problems, and both can be solved using methods similar to those used to solve equations. The triangle inequality, for instance, stipulates that the length of the remaining side of a triangle is more than or equal to the sum of the lengths of any two of its sides.

We are given that,

A triangle has sides measuring 8 inches and 12 inches. If x represents the length in inches of the third side

8+12=20

so it has to be less than 20, and 12-8=4,

So it has to be more than 4,

So the only answer that makes sense is

4<x<20.

Therefore, option B is correct.

The radius of a circle is 3 m. Find its circumference in terms of pi

Answers

Gotcha, bro.

(I don't know what pi is, so I'm gonna assume that it is 3.14)

C=pi x diameter

First, multiply the radius by 2 so you have the diameter.

3x2=6

Second, multiply 3.14 (pi) by 6 (diameter)

3.14x6=18.84

Therefore, the circumference is 18.84.

A circle is a two dimensional figure with a radius and circumference of 2πr.

We have,

The circumference of a circle is given by the formula:

C = 2πr

where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14.

In this case, the radius of the circle is 3 meters.

Substituting this value in the formula, we get:

C = 2πr

C = 2π(3)

C = 6π

When Brandon went bowling, it cost $4.95 per game, plus a one-time fee to rent the shoes. Brandon played 5 games and paid $32. Write and solve linear equation to find the cost to rent the shoes.​

Answers

I think the equation would be
y=4.95x +7.25
The cost of the shoes in this instance would be 7.25.
Since he play 5 games, and each one cost 4.95, you would multiply the two getting 24.75. Since he paid 32, you would subtract what he paid total from the amount for just the games and you would get 7.25.
Using the equation y=4.95(5) + 7.25, it would equal 24.75+7.25 which is equal to 32.

What is the relationship between rigid motions and congruence?​

Answers

Answer:

Rigid Motion and Congruence Two figures are congruent if and only if there exists one, or more, rigid motions which will map one figure onto the other. (thus maintaining the conditions for the figures to be congruent).

Step-by-step explanation:

Two figures are congruent if and only if one or more rigid movements can map one figure onto the other, according to the link between rigid motion and congruence.

Rigid motions and congruence are closely related concepts in geometry.

Rigid motions are transformations that preserve the shape and size of a geometric figure.

They include translations, rotations, and reflections.

Congruence, on the other hand, refers to the relationship between two geometric figures that have the same shape and size.

When two figures are congruent, it means that they can be transformed into each other using a combination of translations, rotations, and reflections, which are all types of rigid motions.

In other words, if two figures are congruent, it implies that there exists a sequence of rigid motions that can be applied to one figure to transform it into the other figure.

Conversely, if two figures can be transformed into each other through rigid motions, then they are congruent.

The key idea is that rigid motions preserve the length of segments, the measure of angles, and the overall shape of figures.

By using rigid motions, we can establish congruence between geometric figures.

This concept is fundamental in geometry as it allows us to compare and analyze shapes and their properties.
