Tracey bought a diamond ring appraised at $1200 at an antique store. If diamonds have appreciated in value at an annual rate of 12%, what was the value of the ring 10 years ago? (Round your answer to the nearest dollar.)
Answer:
1600 / 1.1^10 = $616.87
Step-by-step explanation:
Im not so sure, but here
the value of the diamond ring 10 years ago was approximately $419.47
To find the value of the diamond ring 10 years ago, we need to calculate its original value before the annual appreciation.
Let's assume the original value of the ring 10 years ago was "x" dollars.
After 10 years, with an annual appreciation rate of 12%, the value of the ring became $1200.
The formula to calculate the future value (FV) of an investment with compound interest is:
FV = PV * (1 + r)ⁿ
where:
FV = future value
PV = present value (original value)
r = annual interest rate (as a decimal)
n = number of years
In this case, we have:
FV = $1200 (present value after 10 years)
r = 12% (0.12 as a decimal)
n = 10 years
Now, we can rearrange the formula to find the original value (PV):
PV = FV / (1 + r)ⁿ
PV = $1200 / (1 + 0.12)¹⁰
PV = $1200 / 2.85610019
PV ≈ $419.47
So, the value of the diamond ring 10 years ago was approximately $419 (rounded to the nearest dollar).

Which steps could be part of the process in algebraically solving the system of equations, y + 5x = x + 10 and y = 4x – 10?
Select two options.
y=x2 + 5x + 10
y + 5x = x2 + 10 + 4x - 10
0 = x2-9x 0 = x2 - 9x + 20
One x-value of a solution to the system is 4.
y=x2 + 5x + 10
y + 5x = x2 + 10 + 4x - 10
0 = x2-9x 0 = x2 - 9x + 20
When are two angles complementary?
Answer:
90 degree's
Step-by-step explanation:
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees

Two angles are complementary when they add up to [tex]\tt{90\textdegree}[/tex].
For example:-
Angles whose measures are 60º and 30º are complementary because they add up to 90º.
Now, supplementary angles add up to [tex]\tt{180\textdegree}[/tex].
For example, angles whose measures are 140º and 40º are supplementary because they add up to 180º.

Steve hade 17 pencils in his backpack. this represents 5 more than 6/7 the number of pencils that Clyde has in his backpack
Answer:
Clyde has 14 pencils in his backpack
Step-by-step explanation:
Let x be the number of pencils that Clyde has in his backpack.
We can translate this statement “Steve hade 17 pencils in his backpack. this represents 5 more than 6/7 the number of pencils that Clyde has in his backpack” mathematically like this :
[tex]17=5+\frac{6}{7} x \\\\ \Longleftrightarrow 17-5=\frac{6}{7} x \\\\ \Longleftrightarrow 12=\frac{6}{7} x \\ \\\Longleftrightarrow x=\frac{12\times 7}{6} =14[/tex]
Let he has n pencils
So
[tex]\\ \rm\hookrightarrow \dfrac{6n}{7}+5=17[/tex]
[tex]\\ \rm\hookrightarrow \dfrac{6n}{7}=12[/tex]
[tex]\\ \rm\hookrightarrow 6n=84[/tex]

Before a renovation, a movie theater had 120 seats. After the renovation, the theater has 162 seats. What is the approximate percentage increase of the number of seats in the theater? If necessary, round to the nearest tenth of a percent.
Answer:
35%
Step-by-step explanation:
Percent increase is (new number - old number) / old number
(162 - 120) / 120 = 42 / 120 = 0.35 = 35%

The graph of the Function F(x) is shown below. What is the value of f^-1(1)
Answer: [tex]f^-1(1)=-1[/tex]
Step-by-step explanation:
From the graph given we can derive the function [tex]f(x)[/tex]
[tex]f(x) = .5x + 1.5[/tex]
To solve [tex]f^-1(1)[/tex] we need to find the inverse function of [tex]f(x)[/tex].
Inverse functions are functions that essentially "reverse" the mapping of the domain ([tex]x[/tex]) and range ([tex]y[/tex]) of the parent function.
To find the inverse function [tex]f(x)[/tex] we need to solve for x in terms of y.
[tex]y = .5x + 1.5[/tex]
[tex]y - 1.5 = .5x[/tex]
[tex]\frac{y - 1.5}{.5} = \frac{.5x}{.5}[/tex]
[tex]x=2y-3[/tex]
from this, we can derive that
[tex]f(y)^-1=2y-3[/tex]
this can also be written as a function of x
[tex]f(x)^-1 = 2x-3[/tex]
both functions are identical.
take one of these functions and you can find that
[tex]f^-1(1) = 2(1) - 3[/tex]
[tex]f^-1(1) = -1[/tex]

[tex]7x + 2 = y[/tex]
[tex]7x = y - 2[/tex]

Calculations ↓Remember , inverse functions do the opposite things in the opposite order.
Here's what happened to x here :
First , it's been multiplied by 7 .Then , 2 has been added to it .We can easily find the inverse of any function by following these steps :
Set the function equal to y as follows :f(x)=7x+2
y=7x+2
2. Now , switch y and x places :
x=7y+2
3. Solve for y .
First , subtract 2 on both sides :
x-2=7y
Divide by 7 on both sides :
[tex]\text{y=$\displaystyle\frac{x-2}{7}$}}[/tex]
We've found the inverse function of f(x)=7x+2.[tex]\tiny\text{hope\:helpful}[/tex]

The given equation represents a function and inverse of the function exist if x ≥ 6.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
y = 2(x – 5)² – 6
Part A:
Using vertical line test, we can find the whether the graph is a function or not.
After drawing a graph for the given curve, and drawing a vertical line.
The vertical line touches only one point for the one input.
The given equation represents a function.
Part B:
Replace x → y and y → x
x = 2(y – 5)² – 6
2(y – 5)² = x + 6
[tex]\rm y^-^1 = \sqrt{\dfrac{x+6}{2}} +5[/tex]
Plug x = 1 in the y:
y = 26
Plug [tex]\rm y ^-^1[/tex] = 1 in inverse of a function:
x = 26
Thus, the given equation represents a function and inverse of the function exist if x ≥ 6.
