The inverse of f(x) = x2 – 3 is
f-() = x2 +3
:: - (2) = V2 + 3
:: f-(x) = V2 - 3
:: f-1 (2) = 1 - 3
Answer:
f ⁻¹(x) = [tex]\sqrt{x + 3}[/tex]Step-by-step explanation:
Find the inverse of f(x) = x² - 3
Substitute x with y and f(x) with x and solve for y:
x = y² - 3y² = x + 3[tex]\sqrt{y^2}[/tex] = [tex]\sqrt{x + 3}[/tex]y = [tex]\sqrt{x + 3}[/tex]Replace y with f⁻¹(x):
f ⁻¹(x) = [tex]\sqrt{x + 3}[/tex]Step-by-step explanation:

Find an equivalent ratio in simplest terms:
30 : 24
Answer:
5 : 4
Step-by-step explanation:
Given
30 : 24 ( divide both parts by 6 )
= 5 : 4 ← in simplest form
Answer:
5/4.
Step-by-step explanation:
1. Find the GCD (or HCF) of numerator and denominator. GCD of 30 and 24 is 6.
2. 30 ÷ 624 ÷ 6.
3. Reduced fraction: 54. Therefore, 30/24 simplified to lowest terms is 5/4.
Solve the simultaneous equations
5x + 3y = 41
2x + 3y = 20
Do not use trial and improvement
The solution to the system of equation is (7, 2)
Using the simultaneous equation:
5x + 3y = 41
2x + 3y = 20
using elimination method
Subtract equation 1 from 2 to have:
5x - 2x = 41 - 20
3x = 21
x = 21/3
x = 7
Substitute x = 7 into equation 1 to get y
5x + 3y = 41
5(7) + 3y = 41
35 + 3y = 41
5y = 41 - 35
3y = 6
y = 6/3
y = 2
Hence the solution to the system of equation is (7, 2)

how to calculate interest on a loan
Answer:
Gather information like your principal loan amount, interest rate and total number of months or years that you’ll be paying the loan.Calculate your total interest by using this formula: Principal Loan Amount x Interest Rate x Time (aka Number of Years in Term) = Interest.If you take out a five-year loan for $20,000 and the interest rate on the loan is 5 percent, the simple interest formula works as follows:
$20,000 x .05 x 5 = $5,000 in interest
You might encounter simple interest on short-term loans. However, the way most banks and lenders charge interest is more complicated.

Which correctly explains the number of solutions of the following system of linear
equations?
- 3x + 3y = 12
y = x + 4
А The graphs of the equations are parallel lines because they have the same slope
but different y-intercepts. The system has no solution.
B The graphs of the equations are lines that intersect at one point because the
equations have the same slope but different y-intercepts. The system has
exactly one solution.
с
The graphs of the equations are lines that intersect at one point because the
equations have the same slope and same y-intercept. The system has exactly
one solution.
D The graphs of the equations are the same line because the equations have the
same slope and same y-intercept. The system has infinitely many solutions.
Answer:
D I dont know if im right though
Step-by-step explanation:
The system of equations are same and graphs of the equations are the same line because the equations have the same slope and same y-intercept. The system has infinitely many solutions.
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
The first equation is -3x + 3y = 12 be equation (1)
y = x + 4 be equation (2)
Adding 3x on both sides , we get
3y = 3x + 12
Divide by 3 on both sides , we get
y = x + 4 be equation (3)
So , the equation ( 2 ) is same as equation ( 3 )
Now , the slope of the equation is m = 1 and the y intercept is b = 4
Hence , the equations have infinite solutions

Sum of interior angles is 540°
x = 90°
m∠B = 90°
m∠E = 100°
Step-by-step explanation:
to find the sum of the interior angles you take the number of sides, deduct two, and multiply by 180
a 5-sided figure would be (n - 2)·180° = 3(180) = 540°
add together all five angle measures and set equal to 540; combine like terms and solve for 'x'
220 + 130 + 130 + x + x + 10 = 540
350 + 2x + 10 = 540
2x + 360 = 540
2x = 180
x = 90

find the area of the largest circle help me out i will have points
Answer: 254.34 ^ 2
Step-by-step explanation:
To find the area of the circle use its formula
A = Pi * R^2 / Area equals pie times radius squared
The two circles diameter combined is 18 meaning the radius is 9
So we plug 9 into the formula
A = 3.14 * 9^2
A = 3.14 * 81
A = 254.34 ^ 2
