Answer:
Slope =3
Step-by-step explanation:
3x-y=4 Subtract 3x from both sides
-y=-3x+4 Divide both sides by -1
y=3x-4 your slope is the number before the x.
The school's newspaper has asked you to contact 100 of the approximately 1100 students at the school to gather information about student opinions regarding food at your school's cafeteria. (c) You decide to conduct a survey about the quality of food served in the school cafeteria by randomly selecting students as they leave the cafeteria after lunch on a specific day next week. Describe a source of bias that may result from using this method. Be sure to use the correct terminology, and indicate the direction of the potential bias.
Answer:
Sampling bias
Step-by-step explanation:
Sampling bias is due to the mistaken manner of selection of the respondents for the survey when conducting market research or similar survey. The sampling bias error is said to have occurred when the sample selection procedure, methodology, or process focuses on part of the population with a particular attribute, rather than being a random sample. Such that a given subset of the of the population are selected for the survey, which results in a biased sample.
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]

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. proportional
B. complementary
C. supplementary
D. congruent
The isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent. That is option D.
What is an isosceles triangle theorem?An isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite to these sides are congruent.
This is because the two side of the triangle are identical leading to the angles opposite them being equal too.
Therefore, the isosceles triangle theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent.

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.

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
