Determine if the set of ordered pairs is a relation or function.
I need this 6 questions by tomorrow
Answer:
The answwer for question 6 is -3x+10xw
Step-by-step explanation:
When given a question like this, you have to separate the variables by adding the one with the same variable together. If you add 5x and -8x you will get -3x and if you add 7w with -7w, you'll get 0w which isn't needed in the equation. 20xw would be alone.

find the y-intercept of the graph of 2x-5y=10
Answer:
y-intercept: ( 0 , − 2 )
Step-by-step explanation:
To find the y-intercept, substitute in 0 for x and solve for y
Answer:
(0,-2)
Step-by-step explanation:
Start with:
[tex]2x-5y=10[/tex]
We are going to want this equation in slope-intercept form.
[tex]y=mx+b[/tex]
[tex]mx=slope[/tex]
[tex]b=y-intercept[/tex]
To get the equation in slope intercept from, start by subtracting [tex]2x[/tex] from both sides of the equation:
[tex]-5y=-2x+10[/tex]
Now, divide both sides of the equation by [tex]-5[/tex]:
[tex]y=-\frac{2}{5}x -2[/tex]
[tex]b=-2[/tex]
[tex](0,-2)[/tex]

Step-by-step explanation:
If point (a,b) lies on the graph y=f(x), the graph of f^-1 (x) must contain point:
Given:
Point (a,b) lies on the graph [tex]y=f(x)[/tex].
To find:
The point which is must be lies on the graph of [tex]y=f^{-1}(x)[/tex].
Solution:
According to the definition of an inverse function, if a function is defined as
[tex]f=\{(x,y):x\in R,y\in R\}[/tex]
then, its inverse is defined as
[tex]f^{-1}=\{(y,x):x\in R,y\in R\}[/tex]
It means, we have to interchange x and y-coordinate of the points which lies on the function f to get f⁻¹.
We have a point (a,b) lies on the graph [tex]y=f(x)[/tex]. So, (b,a) must be lies on the graph of [tex]y=f^{-1}(x)[/tex].
Therefore, the correct option is (1).
By the definition of inverse function,the point (a,b) lies on the graph [tex]\bold{y= f(x).}[/tex] So, (b,a) must be lies on the graph of [tex]\bold{y=f^{-1} (x)}[/tex].
Given:
Point (a,b) lies on the graph y= f(x).
Find:
The graph of [tex]\bold{y=f^{-1} (x)}[/tex] must contain that point.
As per the definition of inverse function, if two one-to-one functions f(x) and g(x). If (f∘g)(x)=x and (g∘f)(x)=x. Then, we say that f(x) and g(x) are inverses of each other.
[tex]\bold{f=\{ (x,y):x\epsilon R,y\epsilon R\}}[/tex]
Then, its inverse is defined as
[tex]\bold{f^{-1} =\{ (y,x):x\epsilon R,y\epsilon R\}}[/tex]
Therefore, we have to interchange x and y-coordinate of the points which lies on the function f to get f⁻¹.
Thus, the point (a,b) lies on the graph [tex]y= f(x).[/tex] So, (b,a) must be lies on the graph of [tex]y=f^{-1} (x)[/tex].

A school chess club needs to raise at least $750 to attend a state competition. The club has already raised $400 and there are 4 months remaining until the competition. Which inequality and statement can be used to determine the dollar amount the club will need to raise during the remaining months?
Answer:
400+4n ≥ 750; The club will need to raise an average of $87.50 or more per month.
Step-by-step explanation:
The inequality will be 400+4n ≥ 750 and the club will need to raise an average of $87.50 or more per month.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.
Given that a school chess club needs to raise at least $750 to attend a state competition. The club has already raised $400 and there are 4 months remaining until the competition.
The inequality will be written as,
400+4n ≥ 750
4n ≥ 750 - 400
4n ≥ 350
n ≥ 350 / 4
n ≥ $87.5

The length of a rectangle is 4 m shorter than its width. If the perimeter of the rectangle is 18 m, find its length and width.
Group of answer choices
2(x - 4) + 2x = 18, where x represents the width.
2x - 8 + 2x = 18 (Distribute 2)
4x - 8 = 18 (Add like terms)
4x = 26 (Add 8 to both sides)
x = 6.5 (Divide 4 from both sides)
Length = x - 4 (Length is 4 less m than Width [x - 4])
6.5 - 4 = 2.5 (Substitue in x)
Length = 2.5
The length is 2.5 meters and the width is 6.5 meters.
You can check by adding 2.5 + 2.5 + 6.5 + 6.5 = 18.

What is 713.49 written in standard form as powers
Answer:
one hundred seven thirteen and forty nine hundreds standard form
Step-by-step explanation:
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

Write a quadratic function in standard form with zeros 1 and -10 plzzzz helppp meee
Answer:
[tex]f(x)=x^2+9x-10[/tex]
Step-by-step explanation:
Standard Form of Quadratic Function
The standard representation of a quadratic function is:
[tex]f(x)=ax^2+bx+c[/tex]
where a,b, and c are constants.
The factored form of a quadratic equation is:
[tex]f(x)=a(x-\alpha)(x-\beta)[/tex]
Where [tex]\alpha[/tex] and [tex]\beta[/tex] are the roots or zeros of f.
The question gives the zeros of the function: 1 and -10. This makes our function look like:
[tex]f(x)=a(x-1)[x-(-10)][/tex]
[tex]f(x)=a(x-1)(x+10)[/tex]
Operating:
[tex]f(x)=a(x^2+10x-x-10)[/tex]
Joining like terms:
[tex]f(x)=a(x^2+9x-10)[/tex]
Since we are not given any more conditions, we choose the value of a=1, thus. the required function is:
[tex]\boxed{f(x)=x^2+9x-10}[/tex]
