Consider the following table.
- Will the order pairs listed in the table form a straight line when plotted? Explain.
- Explain why the relationship represented in the table is non-proportional.
Answers
Answer:
No
Step-by-step explanation:
There is no pattern hence it will not form a straight line
There will be no straight line as there is no consistency in proportionality constant.
What is proportionality constant?The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality.
The relationship can be described as y = k x or y = k/x
As, from constant of proportionality
y = k x
k= y/x
k= 53/(-2)= -53/2 = -26.5
and, k= -22/1 = -22
and, k = -47/2 = -2.35
As, there no consistency in proportionality constant.
Hence, the table does not form straight line.

Question:
The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse. Which is an equivalent equation solved for y?
Answer:
[tex]y = \frac{a}{\pi x}[/tex]
Step-by-step explanation:
Given
[tex]a = \pi xy[/tex]
Required
Solve for y
The question implies that, we make y the subject of formula:
This is done as follows:
[tex]a = \pi xy[/tex]
Divide through by [tex]\pi x[/tex]
[tex]\frac{a}{\pi x} = \frac{\pi xy}{\pi x}[/tex]
Isolate y on the right hand side
[tex]\frac{a}{\pi x} = y[/tex]
Reorder
[tex]y = \frac{a}{\pi x}[/tex]
Hence, the solution to the question is: [tex]y = \frac{a}{\pi x}[/tex]

The perimeter of a rectangular parking lot is 292 m.
If the length of the parking lot is 81 m, what is its width?
Answers
Answer:
the answer would be 211
Step-by-step explanation:
you simply add the length and width together to find perimeter. since you have the total perimeter and the length you would instead subtract the two.
292-81= 211
Answer:
68m
Step-by-step explanation:
The perimeter of a rectangle with length and width is given by the following.
P=21+2w
We need to find w when P=292 m and l+78m .
Using these values in the equation above, we'll solve for w.
P=21+2w
292=2(78)+2w
292=156+2w
136=2w
68=w
Subtracting 156 from both sides
Dividing both sides by 2
So the width of the parking lot is 68m

use the subsitution method to slove the system of equations.Choose the correct ordered pair. x+3y=9 y=x-5
Answers
Explanation:
Answer:
(6, 1)
Step-by-step explanation:
We are given the equation for (y), [y=x-5]
So we can implement that in all the places the (y) are in the other equation.
x+3(x-5)=9
x+3x-15=9
add 15 to each side
4x=24
Divide each side by 4
x=6
Now we can apply our (x) into one of the equations.
y=(6)-5
y=1
So our solution is (6, 1)

I need the slope and the y - intercept in the equation. I’ll give you a if you help me
Answers
Answer:
m = slope = 1/2The y-intercept = (0, 5) The equation of the line is:[tex]y=\frac{1}{2}x+5[/tex]
Step-by-step explanation:
Considering the line graph
Some of the points on the line are given by
(0, 5)(2, 6)(4, 7)(6, 8)Finding the slop between any two given points
Let us take the point (0, 5) and (2, 6)
[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:5\right),\:\left(x_2,\:y_2\right)=\left(2,\:6\right)[/tex]
[tex]m=\frac{6-5}{2-0}[/tex]
[tex]m=\frac{1}{2}[/tex]To the y-intercept, set x = 0.
We already know that when x = 0, the value of y = 5
so
The y-intercept = (0, 5)Equation of line can be obtained using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = 1/2 and any point let say (2, 6)
[tex]y-6=\frac{1}{2}\left(x-2\right)[/tex]
add 6 to both sides
[tex]y-6+6=\frac{1}{2}\left(x-2\right)+6[/tex]
[tex]y=\frac{1}{2}x+5[/tex]
Therefore, the equation of the line is:

Answers
Answer:
10 pencils
Step-by-step explanation:
Given that:
Number of pencils bought by Sam and Sara are the same.
Let the number of pencils bought = x
Sam put 1/4 in his pencil box
Sara put 1/2 in her pencil box
1/4 of Sam's pencil = 5
That is ;
1/4 of x = 5
x /4 = 5
x = 20
Hence, number of pencils Sara put in her box
:
1/2 of 20
1/2 * 20
20/2
= 10
10 pencils
