What is the constant of proportionality?
Enter your answer in the box.
Answers
Answer:
12
Step-by-step explanation:
The constant of proportionality is the slope of the line, the ratio of the y-coordinate to the x-coordinate.
k = 36/3 = 12 . . . . . from the lower left point (not the origin)
__
Additional comment
This comes from the equation for a proportion:
y = kx
Solving for k, we get ...
k = y/x
A proportion always graphs as a line through the origin. The slope of it is k, the constant of proportionality.

Solve 2x + 8 + 5x - 2 = 90
Answers
Answer:
x=12
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+8+5x−2=90
Step 1: Simplify both sides of the equation.
2x+8+5x−2=90
2x+8+5x+−2=90
(2x+5x)+(8+−2)=90(Combine Like Terms)
7x+6=90
7x+6=90
Step 2: Subtract 6 from both sides.
7x+6−6=90−6
7x=84
Step 3: Divide both sides by 7.
7x7=847
x=12

If h(x) = 2x+3 and g(x) = 3x-2, find the value of goh(5).
Answers
Answer:
h(x)=2x+3
g(x)=3x-2
First we will find goh(x) then we will put the value of x i.e 5.
goh(x)= 3(2x+3)-2
goh(x)=6x+9-2
goh(x)=6x+7
Now put the value of x, we get
goh(5)=6(5)+7
We get the answer 37

write an equation of a line through (5,6) and perpendicular to the line through (4,8) and (-2,-18)
need this for test
Answers
Answer:
[tex]y-6=-\frac3{13}(x-5)[/tex]
Step-by-step explanation:
Get the slope of the line between the two points. As usual, [tex]m= \frac{\Delta y}{\Delta x}= \frac{8-(-18)}{4-(-2)}=\frac{8+18}{4+2}=\frac{26}{6}=\frac{13}3[/tex]
You want the perpendicular to it, so take it's inverse and change its sign:
[tex]m_p=-\frac3{13}[/tex]
At this point, it's just using the point-slope form, and you're done - unless you're required to provide the line in a specific way, which usually means just crunching numbers and rewriting the equation
[tex]y-y_0=m_p(x-x_0)\\y-6=-\frac3{13}(x-5)[/tex]
Answer:
y=-3/13x+7.15384615385
Step-by-step explanation:
y=mx+b
We want to find the slope first so will find the slope of the line that is perpendicular to our line.
y2-y1/x2-x1
-18-8/-2-4=
-26/-6=
13/3
The slope of the other line is 13/3
To find the slope of our line we can do the opposite reciprocal of 13/3 which is -3/13.
Let's plug that in with the other values to find y-intercept
6=-3/13*5+b
6=-1.15384615385+b
b=7.15384615385

Prior to the 2008 Republican primary for President, the December 21, 2007 Grand Haven Tribune had an article about results from a poll of 621 likely Michigan Republican voters. Quoting from the article: The survey of 621 likely Republican primary voters shows Romney at 21 percent, Huckabee at 19 percent, Guiliani at 12 percent and John McCain at 10 percent. Ron Paul and Fred Thompson each got 4 percent, while Duncan Hunter and Tom Tancredo each got 1 percent.
Required:
a. What is the sample size?
b. Make a frequency table of the results that includes both frequencies (counts) and relative frequencies
Answers
Answer:
a
The sample size is n = 621
b
Voters Relative Frequency Frequency
Romney 0.21 130
Huckabee 0.19 118
Guiliani 0.12 75
John McCain 0.10 62
Ron Paul 0.04 25
Fred Thompson 0.04 25
Duncan Hunter 0.01 6
Tom Tancredo 0.01 6
Undecided votes 0.28 174
Step-by-step explanation:
From the question we are told that
The number of voters is n = 621
The voter election aspirants and their relative frequency are
Romney , 0.21
Huckabee , 0.19
Guiliani , 0.12
John McCain ,0.10
Ron Paul , 0.04
Fred Thompson 0.04,
Duncan Hunter 0.01
Tom Tancredo 0.01
Undecided votes 0.28
This undecided vote is used to represent votes that did not count and it is obtained by subtracting the other relative frequencies from 1 (i.e 100%)
Generally the frequency is mathematically represented as
Romney , 621 * 0.21 = 130
Huckabee , 621 * 0.19 = 118
Guiliani , 621 * 0.12 = 75
John McCain 621 * 0.10 = 62
Ron Paul , 621 * 0.04 = 25
Fred Thompson 621 * 0.04 = 25
Duncan Hunter 621 * 0.01 = 6
Tom Tancredo 621 * 0.01 = 6
Undecided votes 621 * 0.28 = 174
So the table is
Voters Relative Frequency Frequency
Romney 0.21 130
Huckabee 0.19 118
Guiliani 0.12 75
John McCain 0.10 62
Ron Paul 0.04 25
Fred Thompson 0.04 25
Duncan Hunter 0.01 6
Tom Tancredo 0.01 6
Undecided votes 0.28 174

If I dilate a 2x2 square by a scale factor of 3, what will be the new area?
Answers
Answer:
36 square units
Step-by-step explanation:
A 2x2 square has sides that are 2 units long.
When you dilate by a factor of 3, each side has a length 3 times the original length. 2 * 3 = 6. Each side is now 6 units long.
area = side * side = 6 units * 6 units = 36 units^2
