The following set of ordered pairs represents y as a function of x.
{ (9,8), (-2, -14), (6, 2), (-3, -16), (______)}
Which of the following could be the missing ordered pair?
A (9,-8)
B (-3, 9)
C (-9, 8)
D (6,-2)
============================================================
Explanation:
The point (9,8) is in the original set of ordered pairs.
We cannot include (9,-8) since x = 9 is already listed. We can't have repeated x values. If x repeats, then we don't have a function.
This rules out choice A.
Choices B and D are eliminated for similar reasoning.
Choice C can be included because x = -9 hasn't been mentioned yet.
Note: A function is when any given x value leads to exactly one y value.

Step-by-step explanation:
Question 42
16x² - 25y²The identity to be used is : a² - b² = (a - b)(a + b)(1) (4x - 5y)(4x + 5y)Answer:
(1) (4x - 5y)(4x + 5y)
Step-by-step explanation:
Difference of Two Squares: [tex]a^2-b^2=(a-b)(a+b)[/tex]
Therefore, we can use The Difference of Two Squares to factor this expression quickly.
Given expression: [tex]16x^2-25y^2[/tex]
[tex]16=4^2 \implies 16x^2=4x \cdot 4x=(4x)^2[/tex]
[tex]25=5^2 \implies 25y^2=5y \cdot 5y=(5y)^2[/tex]
Therefore:
[tex]16x^2-25y^2=(4x)^2-(5y)^2[/tex]
Using The Difference of Two Squares:
[tex](4x)^2-(5y)^2=(4x-5y)(4x+5y)[/tex]

The equation of line is y = ( 1/4 )x , with slope m = 1/4
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 0 , 0 )
Let the second point be Q ( 8 , 2 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 2 - 0 ) / ( 8 - 0 )
Slope m = 2/8 = 1/4
Now , the equation of line is y - y₁ = m ( x - x₁ )
On simplifying , we get
y - 0 = ( 1/4 ) ( x - 0 )
y = ( 1/4 )x
Hence , the equation of line is y = ( 1/4 )x

Rotate RST 90° counterclockwise around the origin.
The image of the triangle RST when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)
The coordinates of RST are given as:
R = (5,15)
S = (15,15)
T = (10,5)
The rule of 90° counterclockwise around the origin is:
(x,y) -> (-y,x)
So, we have:
R' = (-15,5)
S' = (-15,15)
T' = (-5,10)
Hence, the image of the triangle when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)

\large \frac{1}{4} of a vegetable garden has broccoli and \large \frac{2}{3} of the garden has peppers. how much of the garden has vegetables growing in it?
11/12 of the garden is occupied by broccoli and peppers. Therefore, 11 /12 of the garden has vegetable growing in it.
How to find the how much of the garden growing vegetable?
We know that 1/4 of the garden has broccoli and 2/3 of the garden has peppers, Therefore, let's add up those two fractions to find out how much of the whole garden that has broccoli and peppers.
Therefore,
1/ 4 + 2 / 3 = ?
The denominator needs to be the same. Therefore,
1/4 × 3/ 3 = 3 / 12
2/3 × 4 /4 = 8 / 12
Hence,
3 / 12 + 8 / 12 = 11 / 12
11/12 of the garden is occupied by broccoli and peppers. Therefore, 11 /12 of the garden has vegetable growing in it.

In this diagram, what is the BEST description of the transformation shown?
Answer: B) Rotation
Explanation:
The preimage has been rotated 180 degrees to land on the image.
Proof of this is to note that a point like (2,2) maps to (-2,-2)
The 180 degree rotation rule is [tex](x,y) \to (-x,-y)[/tex]. We flip the signs of each coordinate.
You can accomplish the same thing with two reflections: one over the x axis and the other over the y axis. However, a rotation is more direct.
880$ at 5.25% for 2 years
Answer:
$977.20
Step-by-step explanation:
We will use the compound interest formula to solve this: A = P(1 + R) ^ T
Using this formula we plug-in the values that we already have:
A = 880(1 + .0525) ^ 2
Now if we solve this, we end up with 977.20. That is your answer.

What is the width of the ornament at the volume of 2664.31 cm (use 3.14 for)
Answer:
33.6
Step-by-step explanation:
this is a circle
so
the area of a circle = pi x radius squared(since it's a 2-D shape)
but this is 3-D
so
V = 2664.31 = (4/3)([tex]\pi[/tex][tex]r^{3}[/tex])
you could also use
A = ³√(36 * π * V²) when A is the surface area
but those are too long, so let us just use the answer choices
V = 3.14 x answer choice x radius sqaured
V = 3.14 x 8.6 x radius sqaured
2664.31 = 3.14 x 8.6 x radius sqaured
radius sqaured = 2664.31/3.14 x 8.6
radius sqaured = 2664.31/27.004
radius sqaured can't be made with this
lets skip V
radius sqaured = 2664.31/3.14 x 17.2
radius sqaured = 2664.31/54.008
since 27.004 didn't work, and 54.008 is 2 times as that
radius sqaured = 2664.31/3,14 x 33.6
radius sqaured = 2664.31/105.504 ≈ 25
25 square rooted is 5
so
33.6

All of the choices ask for difference.... it really helps when you draw a number line to solve these types of questions....
but for B you will need to imagine a compass..
alrighty for option B lets examine why it is correct....
Imagine you were standing on a dot (lol)
you walked 1.5 steps to the left <--
then you walked 1.5 steps to the right -->
you can see that you walked in opposite directions and in the end you will be back where you started (aka on the dot, still lol)
meaning the displacement is zero
