Answer:

30 + 6x inches

Step-by-step explanation:

Let the required number be x

If the length of the triangle for the pool table is the twice the sum of 5 and a number

L = 2(5+x)

L = 10+2x

Since the triangle is quadilateral, this means that all sides are equal

Perimeter = 3L

Perimeter = 3(10+2x)

Perimeter = 30+6x

Hence the perimeter, in inches, of the triangle is 30 + 6x inches

What is the inverse of the function f(x) = 2x + 1? h(x) = 1/2x - 1/2

sweet-ann [11.9K]

Answer:

h(x) = x/2 - 1/2

Step-by-step explanation:

Here's the procedure for finding the inverse function algebraically:

1. Replace the label 'f(x)' with the label 'y:' y = 2x + 1

2. Interchange x and y: x = 2y + 1

3. Solve the resulting equation for y: 2y = x - 1, or y = (1/2)(x - 1) or y = x/2 - 1/2

This result corresponds to the 1st given possible answer choice.

The desired inverse function is h(x) = x/2 - 1/2

Solve for x -3x+6=2x-24

ozzi

Answer:

7.5 or 15/2

Step-by-step explanation:

x-3x+6=2x-24 -- Combine like terms

-2x+6=2x-24 -- Add 2x to each side

6 = 4x-24 -- add 24 to each side

30 = 4x -- divide by 4

15/2 or 7.5 = x
