Does anyone know what the answer is

Answer:

8

Step-by-step explanation:

When there are 2 minuses, they convert into + so that the ewuation turns into:

x+15=23

Then you move the +15 after the = sign

Now that you changed the side, you have to change sign so :

x= 23-15

x=8

Answer:

x = -2

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS  is the order of operation, and =

Parenthesis

Exponents (& Roots)

First, add 4x to both sides:

10 - 4x (+4x) = -9x (+4x)

10 = -9x + 4x

10 = -5x

Isolate the variable, x. Divide -5 from both sides:

-5x = 10

(-5x)/-5 = (10)/-5

x = 10/-5

x = -2

x = -2 is your answer.

Hey there!!

To solve this type of question, use these steps.

So, let's work with these steps.

Now,

The equation of a st.line passing through point (2,1) is,

[tex](y - y1) = m1(x - x1)[/tex]

Put all values.

[tex](y - 1) = m1(x - 2)[/tex]

It is the 1st equation.

Another equation is,

y = -2x -3.......(ii)

Comparing the equation with y = mx+c.

Therefore, from equation (ii)

m2 = -2

Now, as per condition of parallel lines,

m1=m2= -2

Putting the value of m1 in equation 1st.

[tex](y - 1) = - 2(x - 2)[/tex]

y - 1 = -2x + 4

y = -2x +5.

Therefore, the equation is y = -2x +5.

Answer:

90 inches squared

Step-by-step explanation:

To do this you would first find the area of the 2 triangles shown on the side so we would do 5 times 2 divided by 2 since that is how we solve this problem so we would get 5 inches squared for the 2 triangles then we would find the area of the square which is 100 since it is a 10 by 10 then you would subtract 5+5 by 100 which is 90 so 90 inches squared would be the answer

Answer:

Your correct answer is 90 sq. in.

Step-by-step explanation:

Find the area of the 2 triangles that are shown on the side.

5 x 2 divided by 2 = 5 sq. in.

Now, find the area of the square

The answer for this is 100 because it is a 10 x 10

Next, subtract

5 + 5 by 100 =  90

Answer:

5.25 feets

Step-by-step explanation:

Given the question :

Abdul wants to hang a square poster that measure 1 1/2 feet on a side in the center of a 12-foot-long wall. How far from the end of the wall should abdul place the side of the poster?

Length of one side of Square poster = 1 1/2 Feets = 3/2 feets

Length of wall = 12 feets long

Since Abdul wants the poster to be centered in the wall; then the picture should be placed such that there must be equal space left on either side of the wall after hanging.

Hence, (12/2 - 1 1/2) = (6 - 0.75) feets

= 5.25 feets

Answer:

6x-4

Step-by-step explanation:

Let's simplify step-by-step.

2(3x−2)−(4x−4x)

Distribute the Negative Sign:

=2(3x−2)+−1(4x−4x)

=2(3x−2)+−1(4x)+−1(−4x)

=2(3x−2)+−4x+4x

Distribute:

=(2)(3x)+(2)(−2)+−4x+4x

=6x+−4+−4x+4x

Combine Like Terms:

=6x+−4+−4x+4x

=(6x+−4x+4x)+(−4)

=6x+−4

Answer:

=6x−4

Answer:

x = -4 thus negative

Step-by-step explanation:

Solve for x:

3 x + 12 = 0

Hint: | Isolate terms with x to the left hand side.

Subtract 12 from both sides:

3 x + (12 - 12) = -12

Hint: | Look for the difference of two identical terms.

12 - 12 = 0:

3 x = -12

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 3 x = -12 by 3:

(3 x)/3 = (-12)/3

Hint: | Any nonzero number divided by itself is one.

3/3 = 1:

x = (-12)/3

Hint: | In (-12)/3, divide 12 in the numerator by 3 in the denominator.

12/3 = (3×4)/3 = 4:

Answer: x = -4

An altitude of a three-dimensional object is best described as option D, "a segment that is perpendicular to the planes containing the two bases."

3D geometry is the study of shapes in 3D space using three coordinates: x-coordinate, y-coordinate, and z-coordinate. To discover the exact location of a point in 3D space, three criteria are required.

An altitude is a line segment drawn from a vertex of a three-dimensional object (such as a pyramid or cone) that is perpendicular to the plane including the base of the object. The altitude can be used to find the height of the object, which is the distance from the vertex to the base along the altitude.

For example, in a pyramid, the altitude is a line segment drawn from the apex (the top vertex) to the center of the base that is perpendicular to the base. In a cone, the altitude is a line segment drawn from the apex to the center of the circular base that is perpendicular to the base.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let y represent the amount of money in Bernie account after x months. Hence:

y = 100x + 200

To make $2500:

Answer: 14

Step-by-step explanation:

To find the distance, find the difference in the x and y values,square them and add them. Then finally find the square root of the number you got after adding them together.  

-2-(-1)= -1

-8 -6 = -14

-14^2 + -1^2 = d^2  where d is the distance

196 + 1 = d^2

197 = d^2

d= [tex]\sqrt{197}[/tex]  

d= 14.0356     rounded to the nearest tenth is 14.

Answer:

23 ^ ( a+b)

Step-by-step explanation:

23^a *23^b

Since the bases are the same, we can add the exponents

23 ^ ( a+b)

Answer:

23^(a+b)

Step-by-step explanation:

A^x*A^y = A^(x+y)

you can think of it like this

A^x = A*A*A*.......*A x times

A^y = A*A*A*....*A y times

therefore A^x * A^y = A*A*A*...*A (x+y) times

=A^(x+y),

so in our case A = 23, and x and y were a and b, so 23^a * 23^b = 23^(a+b)
