Answer:
For this case we can see the table as a set of ordered pairs.
We then have the following ordered pairs:
(-6, -7)
(-1,1)
(0, 9)
(3, -2)
Then, the domain of the function is represented by all the values of x.
We have then:
{x | x = –6, –1, 0, 3}
Answer:
{x | x = –6, –1, 0, 3}

how to write an equation
Answer:
Step-by-step explanation:
An equation is like a sentence, just using a different language. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. It's up to you to learn this language. However, once you know it, you can write in this language! You, too, can write algebraic equations.
Parts of a Mathematical Equation
A mathematical equation, also known as a statement, shows that two separate expressions are equal. The two expressions are usually connected by the "equal-to" (=) sign. You can find the expressions in a mathematical statement by looking at the left-hand side and the right-hand side of the equation, using the = sign as the point of reference.
Example: 2x + 3 = 11
It can be helpful to view equations as a scale in which weights are used to keep it balanced. The scale is balanced when what is placed on the right-hand side is equal in weight to what is on the left-hand side. Solving an equation can also be thought of in terms of adding weight to the left or right-hand side of the scale to balance it out.
Finding the solution to the equation involves manipulating the weights. Whatever is done on the right-hand side of the scale must also be done on the left-hand side to keep the scale balanced.
Your tools for this happen to be, most commonly, addition, subtraction, multiplication, or division.
Answer:
An equation uses symbols and numbers there are SO many equations you could make for example an easy one 6 x 5 = 30 there are two numbers you multiply to get a product. Whenever you write an equation you always put an equal sign which is this: = . This shows what you get from the equation. There are main parts the =, +, -, x, ÷ . All represent what you do to the two numbers you put on both sides of it.

There are 48 students who play the clarinet in a year group of 120.
Write this proportion as a percentage.
Answer:
40%
Step-by-step explanation:
As a Fraction your answer would be [tex]\frac{48}{120}[/tex].
However we are looking for it as a percentage.
In order to calculate, this you can simply find 10%, and 5% of 120.
10% = 12
5% = 6
48 is divisible by 12, therefore 48 / 12 = 4
Giving you your answer which is 40%.

When doing any rotation around the origin, only one number changes integers if it is 90 degrees, in this case rotating 90 degrees will cross the y axis.
This means the y value will remain the same but the integer for the x values will switch.
So the new values are:
U (-10,-7)
V ( -10,-1)
w (-1, -9)

A line goes through the point (0.5, 0.25) and (1, –0.75). What is the slope of the line?
Answer:
-1/2, or -0.5
Step-by-step explanation:
Slope = delta y/delta x
In this situation, you would do.
0. 5 - 1 / 0.25 - (-0.75)
0.5 - 1 = -0.5
0.25 -(-0/75) = 1
-0.5 / 1 = slope
-0.5 = slope
or
-1/2 = slope

Subtract 9x^2+7x-2 from 8x−10
To solve the problem we will firstly rearrange the given expressions to get like terms together.
What are Like terms?like terms are those terms that are having the same variables, also the variables are of the same order as well.
for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.
If we subtract 9x^2+7x-2 from 8x−10, then we will get [tex]-9x^2 +x -8[/tex].
Given to us
[tex](8x-10) - (9x^2+7x-2)[/tex]we know to subtract an expression from another we need to find the like terms of both expressions to carry out the mathematical operation.
therefore,
[tex](8x-10) - (9x^2+7x-2)\\\\=8x-10 - 9x^2-7x+2\\\\= -9x^2 +8x-7x-10+2\\\\= -9x^2 +x -8[/tex]
Hence, if we subtract 9x^2+7x-2 from 8x−10, then we will get [tex]-9x^2 +x -8[/tex].

To solve a multi-variable problem, you need to isolate single variables. To do this, there are two ways to do it. One way you eliminate one of the variables and the other you substitute.
In this example, you are being asked to eliminate one of the variables. To do this, you multiply 2x+2y= 12 by 2 and get 4x+4y = 24.
See how now both equations contain a 4y?
Using this you can subtract one equation from the other.
5x+4y=28
- 4x+4y=24
And then you get x=4
To get the other variable, you substitute 4 in for x (in one of the equations) and then solve for y.
2(4) + 2y =12
8+2y= 12
2y=4
y=2
Therefore, x = 4 and y = 2

What is 2/8 as a decimal and percent
Answer:
0.25 is a decimal and 25/100 or 25% is the percentage for 2/8.
Step-by-step explanation:
The result is: 0.25 and 25% is 2/8 as a decimal and percent.
Here, we have,
given that,
the fraction is: 2/8
now, we have to write as a decimal and percent.
so, we get,
2/8
[ dividing both numerator and denominator by 2 ]
= 1/4
= 0.25
so, we get, 0.25 is a decimal.
now, we have,
0.25 = 25/100 = 25%
so, we have, 25/100 or 25% is the percentage for 2/8.
