The quantities x and y are proportional.
Answer:
r = 1
Step-by-step explanation:
Given the equation of proportion
y = rx ← r is the constant of proportionality
Divide both sides by x
[tex]\frac{y}{x}[/tex] = r
Choose any ordered pair from the table
Using x = 5.8 and y = 5.8 , then
r = [tex]\frac{5.8}{5.8}[/tex] = 1

Anthony has a bank balance of $45. Sara has a bank balance of -$90. Sean has a bank balance of -$208. Marsha has a bank balance of $153. Which is the smallest debt?
9514 1404 393
Answer:
Marsha and Anthony
Step-by-step explanation:
Here a negative bank balance represents a debt. The larger the magnitude of the negative number, the more debt it represents. A positive bank balance corresponds to no debt.
Anthony and Marsha -- no debt . . . . smallest debt
Sara -- $90 in debt . . . . smallest non-zero debt
Sean -- $208 in debt
On those with non-zero debt, Sara has the smallest debt. Overall, Anthony and Marsha have the smallest debt: zero debt.

solve 4x+y=24 and y=-4x+24 using substitution
Answer:
no solutions
Step-by-step explanation:
[tex]4x + y = 24 - - - (a) \\ y = - 4x + 24 - - - (b)[/tex]
substitute for y in (a) with (b):
[tex]4x + ( - 4x + 24) = 24 \\ 0x = 0[/tex]
Answer:
infinite solutions
Step-by-step explanation:
substitute y in the first equation
4x+(-4x+24)=24
4x and -4x cancel out
24/24=1

The shaded rectangle, which is the correct expression of its perimeter
Answer:
2x + 2y - 4
Step-by-step explanation:
The opposite sides are congruent so perimeter (P) is
P = 2(x + 2) + 2(y - 4)
= 2x + 4 + 2y - 8
= 2x + 2y - 4
find an equation for the line passing through (4, 1) and perpendicular to the line 2y+4=6x
Answer:
y = 3x - 11
Step-by-step explanation:
2y+4=6x
2y = 6x - 4
y = 3x - 2
y = 3x + b
1 = 3(4) + b
1 = 12 + b
-11 = b

Answer: i have found one that calculates differences when given a sigma with a sigma rule, you could adjust the formula for patterns, if you create a sigma equation and then apply the formulas and then make up a pattern that falls within it, knowing the connection is they go up in the same numbers or knowing it and for some patterns being able to solve it. when given such a sigma problem such as n=1 sigma 3 is the end point 7n-1 is the rule, we would use the value of n until the end point 3, but consider 7n-1 equal to 6+13+20 which equals 39 since 7*1-1=6 and 7*2-1=13, 7*3-1=20 and 6+13+20 is 39. remeber it is equal to that since we plug the value of n from the starting point to the end point of any sigma. a1=7*n-1=6,a2=7*2-1=13, 7*3-1=21 is what you should manipulate for another sigma problem that calculates the diffrence of a sequence as well as its total. the one equation that calculates the total of your patterns is:∑_(n=0)^20▒〖7n-0=140〗
the ones i know to find that represent the patterns in terms of what it would be in the nth term is 58ns it represents what the pattern would be in the nth terms but it is not equal to the pattern.
finding the nth term by looking for an expression to use for the nth term is the same as finding an expression representing the nth term. the nth term is is the numerical difference in the given series with the letter n on the right of that and the number from the beginning of a series in some cases. one more thing for a negative number at the beginning of a pattern you get the missing number i.e the numerical difference on the left and then and the function of the first number. for example: there is a pattern going from -1 to 19 so the pattern would be -1, 3, 7,11, 15,19. the numerical difference is 4, n is the letter that would come after and -1 , -1 is a function in the area of nth term since the whole expression would be 4n subtracted by 1 and subtraction is a function, a function is a operation in mathes.

9514 1404 393
Answer:
see attached
Step-by-step explanation:
The statement of proportionality tells you ...
m = kr³
The values in the fourth column can tell the value of k:
k = m/r³ = 6.75/1.5³ = 2
Then we have ...
m = 2r³
Solving for r gives ...
m/2 = r³
r = ∛(m/2)
These two relations were used to fill in the spaces in the table. (It is convenient to let a spreadsheet do the calculations.)
What is the inverse of f(x) = 2x2 –4?
Answer:
The inverse of the function is
[tex]{ \underline{f {}^{ - 1}(x) = \sqrt{ \frac{x + 4}{2} } }}[/tex]
Step-by-step explanation:
let the inverse of f(x) be m:
[tex]m = {2x}^{2} - 4 [/tex]
take 4 to the left hand side ( changes sign to positive ):
[tex]m + 4 = {2x}^{2} \\ \frac{m + 4}{2} = {x}^{2} [/tex]
take a square root on all sides:
[tex] \sqrt{ \frac{m + 4}{2} } = \sqrt{ {x}^{2} } \\ \\ x = \sqrt{ \frac{m + 4}{2} } [/tex]
substitute x in place of m:
[tex] {f}^{ - 1} (x) = \sqrt{ \frac{x + 4}{2} } [/tex]
Need help fast!!! This question is for algebra 2 and for a Quiz.
Thank youu.
Step-by-step explanation:
it is unclear what is meant by f1 and f2. do you mean f' and f'' ?
I don't think so, as you mentioned algebra 2.
so, is it just a way to identify different functions ? like function 1 vs. function 2 ?
if that's the case, then both functions represent lines.
both lines go through the origin.
but as their slopes are of same size but different sign, one is actually the mirrored version of the other one (mirrored around the x-axis).
FYI - the created visible pattern (4 lines emanating from the origin) would also indicate that the visible pattern (but not the functions) is also mirrored around the y-axis.
state the domain: A= {(-3,2), (5,4), (7,-3)}
The required domain is [tex]\{-3,5,7\}[/tex].
Given:
A set of ordered pairs is:
[tex]A=\{(-3,2),(5,4),(7,-3)\}[/tex]
To find:
The domain of the given set of ordered pairs.
Solution:
Domain is the set of input values.
In the set of ordered pairs [tex](x,y)[/tex], then the set of all the [tex]x[/tex]-values is domain and the set of all the [tex]y[/tex]-values is range.
We have,
[tex]A=\{(-3,2),(5,4),(7,-3)\}[/tex]
In the above set of ordered pairs, the x-values are [tex]-3,5,7[/tex].
[tex]Domain=\{-3,5,7\}[/tex]
Therefore, the domain of the given set of ordered pairs is [tex]\{-3,5,7\}[/tex].

Is square root of 11+10 a rational or irrational number
Answer:
Irrational Number is the answer
Answer:
[tex] \sqrt{11 + 10} = \sqrt{22} = 4.69041576 [/tex]
THIS IS IRRATIONAL
Step-by-step explanation:
The correct answer is irrational and the reason for that is the decimals for sqrt of 22 are non-recurring, are non-terminating and lastly it cannot be expressed in a form of a fraction.
I hope this makes sense
