HELP! i’m confused! question is in the picture
Answer:
[-6,-3]
Step-by-step explanation:
So we have the compound inequality:
[tex]2x+7\leq x+4\leq 3x+16[/tex]
Let's solve for each of the inequalities:
1)
We have:
[tex]2x+7\leq x+4[/tex]
Subtract x from both sides:
[tex]x+7\leq 4[/tex]
Subtract 7 from both sides:
[tex]x\leq -3[/tex]
So that's one of our answers.
2)
We have:
[tex]x+4\leq 3x+16[/tex]
Subtract 3x from both sides:
[tex]-2x+4\leq 16[/tex]
Subtract 4 from both sides:
[tex]-2x\leq 12[/tex]
Divide both sides by -2. Since we're dividing by a negative, flip the sign:
[tex]x\geq -6[/tex]
Therefore, our entire answer is:
[tex]-6\leq x\leq -3[/tex]
This means all values in between -3 and -6 including -3 and -6.
In interval notation, this is:
[tex][-6,-3][/tex]
So, A is -6.
And B is -3.
And we're done :)

Consider the function f(x) = x2 – 331. Chivonne claims a domain restriction x ≥ 0 produces the inverse function f–1(x) = StartRoot x minus 331 EndRoot . Which statement describes whether Chivonne is correct? The expression for f–1(x) is correct, but the domain restriction is not. The domain restriction is correct, but the expression for f–1(x) is not. Both the expression for f–1(x) and the domain restriction are correct. Neither the domain restriction nor the expression for f–1(x) is correct.
Answer:
The correct option is;
The domain restriction is correct but the expression for f⁻¹(x) is not
Step-by-step explanation:
The expression for the function is given as follows;
f(x) = x² - 331
The inverse function suggested = f⁻¹(x) = √(x-331)
The domain restriction is x ≥ 0
The inverse function if given as follows;
y = x² - 331 (Interchange x and y to get)
x = y² - 331
x + 331 = y²
y = ±√(x + 331)
Given that the domain restriction has been put as x ≥ 0, we select the + case to give;
f⁻¹(x) = √(x + 331)
Therefore, the domain restriction is correct but the expression for f⁻¹(x) is not.
Answer: B
The domain restriction is correct, but the expression for f–1(x) is not.

Money is borrowed at 8% simple interest. After one year, 999.00$ pays off the loan. How much was originally borrowed?
Answer:
PV= $925
Step-by-step explanation:
Giving the following information:
Money is borrowed at 8% simple interest. After one year, $999 pays off the loan.
To calculate the original value of the loan, we need to use the following formula:
PV= FV/(1+i*n)
PV= 999/(1+0.08*1)
PV= $925

If the length of a rectangle is increased by 120%, and its width is decreased by 20%, what is the percentage change in the area of the rectangle? (rea=length*width)
Answer:
The area of the rectangle is increased in 76 percent.
Step-by-step explanation:
The area of a rectangle ([tex]A[/tex]) is represented by the following formula:
[tex]A = w\cdot l[/tex]
Where:
[tex]w[/tex] - Width.
[tex]l[/tex] - Length.
If length is increased by 120 %and width is decreased by 20 %, the percentage change in the area of the rectangle is: ([tex]l = 2.2\cdot l_{o}[/tex], [tex]w = 0.8\cdot w_{o}[/tex])
[tex]A = (2.2\cdot l_{o})\cdot (0.8\cdot w_{o})[/tex]
[tex]A = (2.2)\cdot (0.8)\cdot w_{o}\cdot l_{o}[/tex]
[tex]A = 1.76\cdot A_{o}[/tex]
The area of the rectangle is increased in 76 percent.

The beast, a roller coaster in Cincinnati, Ohio, is 1.4 miles long. How far would you travel in 5 rides?
Answer:
7 miles
Step-by-step explanation:
So we know that theroller coaster is 1.4 miles long for ONE ride. Since we're riding it for more times we would multiply how many miles to how many times we're riding it. So 1.4 *5 which equals 7.
The diagonal of a square is 10m long. What is the length of the side of the square?(Give your answer to the nearest cm)
Answer: 7 cm
Step-by-step explanation: The formula for this type of question is; √2×d÷2 where d stands for the diagonal so, √2×10÷2 = 7.071067812, to the nearest cm is 7cm.
Answer:
7 cm
Step-by-step explanation:
The diagonal divides the square into 2 right triangles.
Using Pythagoras' identity with the diagonal as the hypotenuse.
let x be the side of the square, then
x² + x² = 10²
2x² = 100 ( divide both sides by 2 )
x² = 50 ( take the square root of both sides )
x = [tex]\sqrt{50}[/tex] ≈ 7 cm ( to the nearest cm )

A piece of wood has a width of 5 cm and a height of 10 cm. Its volume is 100 cm? What is the length of the wood?
10,000 cm
2 cm
515 cm
50 cm
Answer:
The length of a piece of wood is 2 cm.
Given:
volume = 100 cm³
width = 5 cm
height = 10 cm
length = ?
Volume is computed by multiplying the length, width, and height of an object.
Volume = length * width * height
100 cm³ = length * 5 cm * 10 cm
100 cm³ = length * 50 cm²
100 cm³ / 50 cm² = length
2 cm = length
to check:
100 cm³ = 2 cm * 5 cm * 10 cm
100 cm³ = 10 cm² * 10 cm
100 cm³ = 100 cm³
Answer:
2 cm
Step-by-step explanation:
