A. In the quadratic regression model, the explanatory variable is time and the response variable is the height.
The explanatory variable (or the independent variable) always belongs on the x-axis (represented as the first column of the table).
What is the regression model?Regression analysis is a set of statistical processes for estimating the relationships between a dependent variable and one or more independent variables.
The response variable (or the dependent variable) always belongs on the y-axis (represented as the second column of the table).

Rewrite the equation in Ax+By=C form.
Use integers for A, B, and C.
y+ 6 = 5(x-3)
Answer:
5x - y = 21
Step-by-step explanation:
Given the linear equation in point-slope form, y + 6 = 5(x - 3):
In order to transform the given equation into its standard form, Ax + By = C, start by distributing 5 into the parenthesis:
y + 6 = 5(x - 3)
y + 6 = 5x - 15
Subtract 5x from both sides:
- 5x + y + 6 = 5x - 5x - 15
- 5x + y + 6 = - 15
Subtract 6 from both sides:
- 5x + y + 6 - 6 = - 15 - 6
- 5x + y = - 21
Divide both sides by -1:
[tex]\frac{-5x + y}{-1} = \frac{-21}{-1}[/tex]
5x - y = 21
On a map, 1 inch equals 15 miles. Two cities are 7 inches apart on the map. What is the actual
distance between the cities?
The actual distance between the cities is miles.
Answer:
105 miles
Step-by-step explanation:
The ratio you have is 1:15
So you must multiply 7 by 15 to find the actual distance in miles.
7*15=105

which line is parallel to the line whose equation is 4x 3y = 7, and also passes through the point (- 5, 2)?
Answer: [I assume: "4x 3y = 7" is really 4x + 3y = 7]
y = -(4/3)x -14/3
Step-by-step explanation:
Rewrite this as y=mx+b, where m is the slope.
4x + 3y = 7
3y = -4x +7
y = -(4/3)x +(7/3)
The slope is -(4/3)
A parallel line will have the same slope, but a specific value of b to allow it to go through the given point (-5,2):
y = -(4/3)x + b
Enter the point and solve for b:
2 = -(4/3)(-5) + b
2 = (20/3) + b
b = 2 - (20/3)
b = 6/3 - 20/3
b = -14/3
y = -(4/3)x -14/3
Find the inverse function in slope-intercept form (mx+b):
f(x)=2x-8
Answer:
[tex]\sf f^{-1}(x) = \dfrac{x}{2}+4[/tex]
Step-by-step explanation:
A function is given to us and we need to find the inverse of the function in slope intercept form . The given function is ,
[tex]\sf\implies f(x) = 2x - 8 [/tex]
Let us assume that y = f(x) , so that ,
[tex]\sf\implies y = 2x - 8 [/tex]
Now interchange the positions of x and y , we have ,
[tex]\sf \implies x = 2y - 8[/tex]
Solve for y in terms of x ,
[tex]\sf \implies 2y = x + 8 \\\\\sf\implies y =\dfrac{x}{2}+4 [/tex]
This is the inverse of the function in slope intercept form. Now we can replace this y with f-¹(x) , as ,
[tex]\sf \implies \boxed{\pink{\frak{f^{-1}(x) = \dfrac{x}{2}+4}}}[/tex]

Hi there!
We are given two exterior angles. Don't panic! We know that exterior angles form a linear pair, which means they add up to 180 degrees.
180-130=50
180-96=84
Now that we have those angles, how can we work out the value of x?
Turns out that all the angles in any triangle add up to 180 degrees.
So
180-84-50=46 degrees.
So the value of x is 46 degrees.
Now let's work out the value of x in the next problem.
180-126=54
180-54-43=83 degrees
So the value of x in this problem is 83 degrees.
Let's move on to the third problem.
At first, it seems like we do not have enough information.
If we know that the right angle is 90 degrees (it is shown by a little square), then we have enough information.
180-90-43=47 degrees
So the value of x is 47 degrees.
Hope this helps you!

O There is no solution.
оо
There is only one solution.
ws
о
All real numbers are solutions.
Answer:
3rd option
Step-by-step explanation:
3(x + 8) - 9x = 6(4 - x) ← distribute parenthesis on both sides
3x + 24 - 9x = 24 - 6x , collect like terms on left side )
24 - 6x = 24 - 6x
Since both sides are the same then any value of x will make the equation true.
That is all real numbers are solutions

Answer:
It is Linear Increasing.
Step-by-step explanation:
If it is a straight line, it is a linear function. if it is NOT a straight line, then it is a non-linear function.
Edit: When the line starts from the top of the y-axis, then it is decreasing. If the line starts from the Origin Point (as shown in the picture you included), then it is increasing. I hope this helps you in Linear and Non-linear relationships.

(4,-3),m=-1 in standard form
Answer:
Step-by-step explanation:
m = -1 ; ( 4 , -3)
y - y1 = m(x - x1)
y - (-3) = -1(x - 4)
y+ 3 = -x + 4
Add x to both side.
x +y + 3 = 0
Subtract 4 from both sides
x + y + 3 - 4 = 0
x +y - 1 = 0
