Answer:
x = 6
Step-by-step explanation:
(x + 2) + (2x + 3) = 23
Combine like terms
3x +5 = 23
Subtract 5 from each side
3x+5-5 = 23-5
3x = 18
Divide each side by 3
3x/3 = 18/3
x = 6
Answer:
x = 6
Step-by-step explanation:
1. Remove parentheses where unneeded. x + 2 + 2x + 3 = 23
2. Add constants. x + 5 + 2x = 23
3. Combine like terms. 3x + 5 = 23
4. Subtract "5" from the constants on both sides of the equation. 3x = 18
5. Divide both sides by 3. 3x/3 = 18/3
6. Simplify. x = 6

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

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):

For the line above, what is the slope? *
Answer: The slope is 2.
Step-by-step explanation:
To get the slope, use this tip: Rise over run
Count how much it rises, which is 4, and how much it "runs' which is 2. Now put rise above run which is 4/2. This simplifies to simply 2.
Answer:
The slope is 2.
Step-by-step explanation:
The points on the line are (1, -2) which can be labeled as x1 and y1, and the other is (3,2) which can be labeled as x2 and y2. you set up the equation in the slope formula, so 2 - - 2 / 3 - 1. Since there are two negatives, the subtraction signs turn into addition signs, and you get 4/2, which simplyfied is 2. Hope this helps :)

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.
