Let f(x)=2x-6. solve f^-1(x) when x=2.

Answers

Answer 1

Answer: $f(x)=2x-6\n y=2x-6\n 2x=y+6\n x=(1)/(2)y+3\n f^(-1)(x)=(1)/(2)x+3\n f^(-1)(2)=(1)/(2)\cdot2+3\n f^(-1)(2)=1+3\n f^(-1)(2)=4$

Answer 2

Answer: a) Calculating f⁻¹(x)

$y=2x-6\n \n x=2y-6\n \n 2y=x+6\n \n y=(x+6)/(2)\n \n \boxed{f^(-1)(x)=(x+6)/(2)}$

b) Calculating f⁻¹(2)

$\boxed{\boxed{f^(-1)(2)=(2+6)/(2)=(8)/(2)=4}}$

The length of the sides of a square are s inches long. A rectangle is six inches shorter and eight inches wider than the square. Express both the length and the width of the rectangle as a function of a side of the square. a) Rectangle width is s + 8 and length is s - 6 b) Rectangle width is s - 8 and length is s + 6

Answers

Answer:

HI,

Answer A

Step-by-step explanation:

Final answer:

The rectangle has a length s - 6 and width s + 8 in terms of the side length s of the square.

Explanation:

The length of the sides of a square is s inches. The rectangle is six inches shorter and eight inches wider than the square. To express the length and width of the rectangle as a function of the side of the square:

Length of the rectangle = Length of the square - 6 = s - 6

Width of the rectangle = Width of the square + 8 = s + 8

Therefore, the correct expression for the length and width of the rectangle is: a) Rectangle width is s + 8 and length is s - 6

Domain of root(3-2x)+root(1-x)

Answers

Answer:

x≤1

Step-by-step explanation:

sqrt( 3-2x) ≥ zero

3-2x ≥ zero

3 ≥ 2x

3/2 ≥ x

x ≤ 3/2

sqrt( 1-x) ≥ zero

1-x ≥ zero

1 ≥ x

x ≤ 1

We need the more restrictive domain since we are adding the two functions

Davinci Digital Media’s wholesale price to the retailer for a digital video camcorder is $1,399.99. Manufacturing costs include $360.00 for production wages and benefits. Production wages and benefits are what percent of the wholesale price to the retailer?

Answers

If you would like to know what percent of the wholesale price to the retailer are production wages and benefits, you can calculate this using the following steps:

x% of $1,399.99 is $360.00
x% * 1,399.99 = 360.00
x/100 * 1,399.99 = 360.00
x = 360.00 * 100 / 1,399.99
x = 25.71%

The correct result would be 25.71%.
