From the given scatter plot with x and y variables, we can say that the correlation is; Negative Correlation.
How to interpret scatter plot correlation?We are told that you kept the balance in your "discretionary spending" envelope.
Now, we are further told that a scatter plot shows the number of days that have passed since you were paid and the amount left in your discretionary spending envelope.
Now, In this case, the day of the salary increases the money spent, that is, the amount of money in the envelope decreases. Thus, as the variable increases and the other decreases, it is a negative correlation.

Word problem to find the translation
Answer:
3 units left and 2 units down
Step-by-step explanation:
The ordered pair is written (x,y) The x tells us the location right or left from the origin (0,0) and the y tells us the up or down from the origin (0,0).
We are translating the point from (6,4) to (3,2) Look at the x values. We start at 6 and move to 3. That means that we moved 3 units to the left.
Now look at the y values. We start at 4 and move to 2. That means that we moved down 2 spaces.

Where is the point (-3,1) located when it is translated four units left and two units up 
Answer:
-5,3. You crawl before you can walk.
Step-by-step explanation:
Answer:
(-7, 3)
Step-by-step explanation:
Original point: (-3, 1)
So original x = -3
4 units left means x coordinate is decreased by 4
So, new x-coordinate = -3 - 4 = -7
Original y coordinate = 1
2 units up means y coordinate increases by 1
So new y-coordinate = 1 + 2 = 3
Translated point = (-7, 3)

Let f(x)=x-2 and g(x)=x²-3 x+2 . Perform each function operation and then find the domain. -2 g(x)+f(x)
The outcome of -2 g(x) + f(x) is 4 x -2 x ² and the domain is [ 0 , 2 ] .
Given,
f (x) = x - 2 and g (x) = x² - 3 x + 2
The question states to find the summation of the function f, that is, f (x) = x - 2, and function g, that is, g (x) = x² - 3 x + 2
Performing the addition operation on these functions is just like simple addition.
This means that when we add the two functions f (x) and g (x), we get
f (x) + g (x) = x - 2 + x² - 3 x + 2
=> f (x) + g (x) = x ² - 2 x
This implies that the summation or addition of the two functions f (x) and g (x) gives x ² - 2 x
needed result = -2 g(x) + f(x) = -2 ( x² - 2 x ) = -2 x ² + 4x = 4 x -2 x ²
To find domain,
y = 4 x -2 x²
=> 4x -2 x² ≥ 0
=> 2 x * ( 2 - x ) ≥ 0
=> 2 x ≥ 0 and 2 - x ≥ 0
=>x ≤ 2 and x ≥ 0
=> the final Domain = [ 0 , 2 ]
Therefore, we get the result of -2 g(x) + f(x) as 4x -2 x ² and the domain as [ 0 , 2 ] .

Using multiple line and angle theorems, the values of each of the 14 angles are given.
Using the geometry theorems :
1.)
∠2 is a right angle = 90°
2.)
∠1 + ∠2 + ∠3 = 180° (sum of angle on a straight line)
90 + ∠1 + 54° = 180°
∠1 = (180 - 144) = 36°
(∠2 and ∠5) ; (∠3 and ∠6) ; (∠1 and ∠4) are vertically opposite ;
Hence,
∠4 = 36°
∠5 = 90°
∠6 = 54°
∠3 = ∠8 = 54° (corresponding angles)
∠9 + ∠8 = 180° (sum of angle on a straight line)
∠9 = (180 - 54) =126°
∠7 = ∠9 = 126° (vertically opposite angles)
∠8 = ∠10 = 54° (vertically opposite angles)
∠4 = ∠13 = 36° (corresponding angles )
∠12 + ∠13 = 180° (sum of angle on a straight line)
∠12 = (180 - 36) =126°
∠11 = ∠13 = 36° (vertically opposite angles)

A quadratic function is shown on the graph.
an upward opening parabola beginning with closed circle at negative 2 comma 4, which decreases to a vertex at 0 comma 0 and then increases to an open circle at 3 comma 9
What is the range of the function?
{x | −2 ≤ x < 3}
{x | −2 < x ≤ 3}
{y | 0 ≤ y < 9}
{y | 0 < y ≤ 9}
The range of the quadratic function is {y |0 ≤ y < 9}
What is the range of a function?The range of a function is the set of output values of the graph. This in other words mean the range of a function is the set of y values of the graph.
How to determine the range of the function?From the question, we have the following parameters:
The parabola opens upwardVertex = (0, 0)Closed circle point = (-2, 4)Open circle point = (3, 9)Write out the vertex
So, we have
Vertex = (0, 0)
Remove the x value
y = 0
From the question, we have
The parabola opens upward
This means that the vertex is a minimum
So, the range is
y ≥ 0
Rewrite as
0 ≤ y
Recall that:
Closed circle point = (-2, 4)
Open circle point = (3, 9)
Remove the x values
Closed circle point = 4
Open circle point = 9
Remove the smaller y value
Open circle point = 9
This means that the highest value of y is at open circle point = 9
This is represented as
y < 9
So, we have
0 ≤ y and y < 9
Combine both
0 ≤ y < 9
Rewrite properly as
{y |0 ≤ y < 9}
Hence, the range of the quadratic function is {y |0 ≤ y < 9}

What is Inequality?Inequality is a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
From the question, we are to determine the inequality that represents the given situation
From the given information, we have that
The length of the laptop is given by 13x - 9 units
and The width of the laptop is given by 4.5x + 8 units
If the length is greater than the width, then we can write that
13x -9 > 4.5x + 8
Hence, the inequality that represents the given situation is 13x - 9 > 4.5x + 8
