The graph given is of inequality x ≤ -7.

What is an inequality?

In Algebra, inequality is a mathematical statement that shows the relation between two expressions using the inequality symbol.

Given is a graph of an inequality, we need to determine the inequality,

So, the graph is cutting the x-axis at -7 and all the numbers less than -7 is covered by the graph,

so the inequality will be x ≤ -7

Hence, the graph given is of inequality x ≤ -7.

solve equation s - 12= 20. s=?

Answers

Answer:

s = 32

Step-by-step explanation:

We have our equation:

s - 12 = 20

And we are trying to find s. Therefore, we can isolate the variable s, which means we have to move all the values from the variables side to the other side, like so:

s - 12 = 20

 +12     +12 (we add 12 to both sides in order to cancel out the -12, and also because whatever we do to one side, you have to do to the other!)

So, now our equation will look like this:

s = 20 + 12,

or,

s = 32

Which happens to be our answer!

Hope this helps :)

Which picture shows a proper
reflection across the red dashed line?
A
B

Answers

Picture B shows a proper reflection across the red dashed line.

What are transformations on the graph of a function?

Examples of transformations are given as follows:

A translation is defined as lateral or vertical movements.A reflection is either over one of the axis on the graph or over a line.A rotation is over a degree measure, either clockwise or counterclockwise.For a dilation, the coordinates of the vertices of the original figure are multiplied by the scale factor, which can either enlarge or reduce the figure.

For a reflection, the orientation of the figure is changed, keeping the same inclination, and the opposite distance to the reflection line, hence picture b shows the proper reflection.

i need help on number 6 and 7 !!! please help!!!! it would be much appreciated

Answers

Answer:

6.) No, you do not agree with Ted.

7.) x = 34 degrees

Step-by-step explanation:

6.) For a triangle to be valid, it must meet these requirements:

a+b>c

a+c>b

b+c>a

If it fails a single one, then it is invalid.

For example: 6+11 is not greater than 4. Therefor, Ted is incorrect

7.) Though you see a square, or rectangle (whatever you want to call it), you can break it up into 2 triangle, only 1 of which you need to solve for.

We have these clues:

angle 1 = x

angle 2 = 56 degrees

angle 3 is a right angle

Any triangle must have its angles sum to 180 degrees

We also know that right angles are equal to 90 degrees.

Our updated clues:

angle 1 = x

angle 2 = 56 degrees

angle 3 = 90 degrees

angles 1+2+3 must equal 180

So we can make this equation:

x+56+90=180

Add like terms and solve for x:

x = 34

1260=(n-2) x 180what is n?

Answers

Answer:

N = 9

Step-by-step explanation:

1. 1260 / 180 = 7

2. Because we removed 2 before, we're going to add 2 because we're doing it in reverse and we get 9, therefore the answer is 9

O (2x+1)(2x+6)
(4x+3)(x+2)

Answers

Answer:  (4x + 3) (x + 2)

Step-by-step explanation:

We can rewrite 4x² + 11x + 6 as 4x² + 8x + 3x + 6

Since 4x² + 11x + 6  = 4x² + 8x + 3x + 6

                                = (4x + 3) (x + 2)

The  factors of the given expression  [tex]4x^2 +11x+6[/tex]  are  (x+8) and (x+3).

A collection of constants, variables connected using one or more arithmetic operator is called an expression.

An algebraic expression or a number that divides another number without leaving any remainder and the quotient is a whole number is called a factor.

The factors of the following expression can be calculated as:

[tex]4x^2 +11x+6[/tex] = [tex]x^2+ 8x+ 3x+24[/tex]

                     = x(x+8) +3(x+8)

                      = (x+8) (x+3)

Thus, the factors of the [tex]4x^2 +11x+6[/tex] are (x+8) (x+3)

Answer:

subtract 20 from both sides

Step-by-step explanation:

1. To find the answer, let's actually try solving the equation first and find the 2nd step.

2. (Solving)

Step 1: Distribute 2 to each term.

[tex](2)(x)+(2)(10)=60[/tex] [tex]2x + 20 = 60[/tex]

Step 2: Subtract 20 from both sides.

[tex]2x + 20 - 20 = 60 - 20[/tex] [tex]2x = 40[/tex]

3. Since we got that the second step was "subtract 20 from both sides," the answer is subtract 20 from both sides.
