The quantities xxx and yyy are proportional. xxx yyy 222 222222 777 777777 999 999999 Find the constant of proportionality (r)(r)left parenthesis, r, right parenthesis in the equation y=rxy=rxy, equals, r, x. r =r=r, equals
Answer:
If the table is:
x=2 y=22
x=7 y=77
x=9 y=99
you can see that 22/2=11 same with 7/77 and 9/99
r=11
Step-by-step explanation:
pretty simple but i probably explained it horribly
The constant of proportionality (r) is 11 for the given variables in the table.
What is the constant of proportionality?The constant of proportionality is the constant value of the ratio of two proportional values. A proportionality relation exists between two changing quantities when either their ratio or product gives a constant.
The table is given in the question consists as:
The value of variable x = 2 when variable y = 22
The value of variable x = 7 when variable y = 77
The value of variable x = 9 when variable y = 99
We have to determine the constant of proportionality (r)
the constant of proportionality (r) = y / x
Substitute the values in the above equation,
the constant of proportionality (r) = 22/2 = 7/77 = 9/99 = 11
the constant of proportionality (r) =11
Thus, the constant of proportionality (r) is 11 for the given variables in the table.

Item 12 You win an online auction for a toy. Your winning bid of $52 is 65% of your maximum bid. How much more were you willing to pay for the toy than you actually paid?
Answer:
$28
Step-by-step explanation:
Given that:
Value of Winning bid = $52
Winning bid 65% of the maximum bid.
To find:
How much more is the maximum bid from the winning bid ?
Solution:
We are given that the winning bid is 65% of the maximum bid.
Using this percentage value, we need to first find the value of maximum bid and then we need to subtract the value of winning bid from the maximum bid to find the answer.
Let the value of maximum bid = $[tex]x[/tex]
As per question statement:
[tex]65%\ of\ x = 52\\\Rightarrow \dfrac{65}{100} \times x =52\\\Rightarrow 5x = 400\\\Rightarrow x = \dfrac{400}{5}\\\Rightarrow x =\$80[/tex]
Therefore, maximum bid = $80
Our answer is:
$80 - $52 = $28

Need help please!!!!!!!
Answer:
First Option {-2 , 0 , 2}
Step-by-step explanation:
A critical point occurs when the derivative is 0 or undefined.
The function in the question is undefined at x = 2 and at x = -2 because if we put x = 2 or x = -2 the denominator becomes 0 hence anything divided by 0 is undefined, and the derivative equals 0 at x = 0 so the critical points are
{-2 , 0 , 2}
Use the quotient rule to find the derivative of the function then equal it to zero
[tex]y=\frac{x^2-1}{x^2-4}\\\\\frac{dy}{dx}=\frac{(x^2-4)(2x)-(x^2-1)(2x)}{(x^2-4)^2}\\\\0=\frac{(x^2-4)(2x)-(x^2-1)(2x)}{(x^2-4)^2}\\\\0=2x^3-8x-2x^3+2x\\0=-6x\\x=0[/tex]

Is it sometimes,never, or always that An integer is less than its opposite
and greater than 0.
Answer:
Sometimes
Step-by-step explanation:
SOMETIMES, An integer is less than its opposite and greater than 0.
This is because a negative integer has a positive opposite, hence a negative integer will be less than its opposite.
However, a positive integer also has a negative opposite so it will be greater than its opposite.
For example, a negative integer of -5 is less than a positive integer of 5 which is it's opposite and at the same time, a positive integer of 5 is greater than its opposite which is negative integer of -5.
Also, even though a positive integer is greater than 0, a negative integer on the other hand is less than 0

What is the average rate of change of f over the interval -1
on a separate sheet of paper and upload the work as a photo. Show all
appropriate work necessary for full credit.
f(x)=
x² - x - 1
Answer:
Average rate of change for the function [tex]f(x)= x^2-x-1[/tex] over the interval -1<x<1 is -1
Step-by-step explanation:
We need to find average rate of change of f over the interval -1 < x < 1
The function given is: [tex]f(x)= x^2-x-1[/tex]
The formula used to find average rate of change is:
[tex]Average\:rate\:of\:change=\frac{f(b)-f(a)}{b-a}[/tex]
We have, a = -1 and b = 1
Finding f(b) when b=1
[tex]f(x)=x^2-x-1\\f(1)=(1)^2-(1)-1\\f(1)=1-1-1\\f(1)=-1[/tex]
Now, finding f(a), when a= -1
[tex]f(x)=x^2-x-1\\f(-1)=(-1)^2-(-1)-1\\f(1)=1+1-1\\f(-1)=2-1\\f(-1)=1[/tex]
Now, putting values and finding average rate of change
[tex]Average\:rate\:of\:change=\frac{f(b)-f(a)}{b-a}\\Average\:rate\:of\:change=\frac{f(1)-f(-1)}{1-(-1)}\\Average\:rate\:of\:change=\frac{-1-(1)}{1-(-1)}\\Average\:rate\:of\:change=\frac{-1-1}{1+1}\\Average\:rate\:of\:change=\frac{-2}{2}\\Average\:rate\:of\:change=-1[/tex]
So, average rate of change for the function [tex]f(x)= x^2-x-1[/tex] over the interval -1<x<1 is -1
HELP. How long is the minor axis for the ellipse shown below?
Given:
The equation of ellipse is
[tex]\dfrac{(x+4)^2}{25}+\dfrac{(y-1)^2}{16}=1[/tex]
To find:
The length of the minor axis.
Solution:
The standard form of an ellipse is
[tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex] ...(i)
where, (h,k) is center, if a>b, then 2a is length of major axis and 2b is length of minor axis.
We have,
[tex]\dfrac{(x+4)^2}{25}+\dfrac{(y-1)^2}{16}=1[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]b^2=16[/tex]
Taking square root on both sides.
[tex]b=\pm 4[/tex]
Consider only positive value of b because length cannot be negative.
[tex]b=4[/tex]
Now,
Length of minor axis = [tex]2b[/tex]
= [tex]2(4)[/tex]
= [tex]8[/tex]
So, the length of minor axis is 8 units.
Therefore, the correct option is B.

pieces of luggage are lost or misdirected
each day by United States airlines. Of
these, 98% are located by the airlines
within 5 days. From a given day’s lost
luggage, at least how many pieces of
luggage are still lost after 5 days?
WRITE AND SOLVE AN INEQUALITY!!!!!! (people just solve without an inequality!)
98% of 25,000 is 24,500.
So from this, we can make the inequality:
25,000 - 500x
x = 5 days.
May I have brainliest please? :)
Answer:
500
Step-by-step explanation:
At least means 25000 and bigger. But 25000 is included in the inequality.
You should write an inequality to to represent the number of pieces of luggage
x ≥ 25000
100% - 98% = 2%
2% of all luggage lost is never found. Multiply both sides of x ≥ 25000 by 2%
2 percent x ≥ 25000 * 2%
2 percent x ≥ 500
Note that 2 percent is not an algebraic variable. 2% is. 2% = 2/100, but that is not what you want on the left.

The population of a city grows exponentially at rate of 8% per year.Find the number of years it takes for the population to be doubled Give your answer correct to the nearest whole number
Answer:
It will take 9 years for the population to double
Step-by-step explanation:
Exponential Growth
The natural growth of some magnitudes can be modeled by the equation:
[tex]P=P_o(1+r)^t[/tex]
Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.
The population of a city grows at a rate of r=8% = 0.08 per year. We are required to find when (t) the population will double, or P=2Po.
Substituting in the equation:
[tex]2P_o=P_o(1+0.08)^t[/tex]
Simplifying:
[tex]2=(1.08)^t[/tex]
Taking logarithms:
[tex]\log 2=\log (1.08)^t[/tex]
Applying the exponent property of logs:
[tex]\log 2=t\log (1.08)[/tex]
Solving for t:
[tex]\displaystyle t=\frac{\log 2}{\log (1.08)}[/tex]
Calculating:
[tex]t\approx 9[/tex]
It will take 9 years for the population to double

An equation for a house's value is y = 7500x + 125000,
where y is the value in dollars and
x is the time in years, starting now.
a) What is the y-intercept of this equation?
b) What does the y-intercept represent?
c) What is the value of the house 2 years from now?
d) At what rate is the house value changing from year to year
9514 1404 393
Answer:
a) 125000
b) the value now
c) 140000
d) 7500 per year
Step-by-step explanation:
a) Comparing the equation to slope-intercept form (y = mx+b) we see that the y-intercept (b) is 125000.
__
b) We presume that "starting now" means x=0 corresponds to "now." The y-intercept is the value when x=0, so the y-intercept represents the value now.
__
c) When x=2, the value is ...
y = 7500(2) +125000 = 140000
The value of the house is projected to be 140000 two years from now.
__
d) The coefficient of x being 7500 means the value will increase 7500 each year.

wa says that 15 years from now his age will be 3 times his age 5 years ago. If a represents William's present age complete the following 25 years 28 years X-15= 3+ 5) x+15= 3(4-5) The equation representing William's claims
Answer:
x+15 = 3(x-5)
Step-by-step explanation
Let the william present age be a, we are to find the equation representing William's claims
15 years from now, williams age will be x+15
5 years ago, his age will be x - 5
if 15 years from now his age will be 3 times his age 5 years ago, this is expressed as;
x+15 = 3(x-5)
Hence the required equation is x+15 = 3(x-5)
