Distance traveled by Deon to ride a bicycle trail = 15 mile

Average speed of Deon to ride a bicycle trail = 20 mi/hour

Let 'T' be the time taken to ride the bicycle trail.

We will use distance speed formula to write the equation to find the time 'T' in hours, for the ride.

Distance =\frac{Speed}{time}

15 = \frac{20}{T}

So, T = \frac{20}{15}

This equation will be used to find the time 'T' in hours for the ride.

Answer: The length is 12 feet and the width is 4 feet.

Step-by-step explanation:

Let L represent the length of the bedroom closet.

Let W represent the width of the bedroom closet..

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

The perimeter of the bedroom closet is 32 ft. This means that

2(L + W) = 32

Dividing through by 2, it becomes

L + W = 32/2

L + W = 16

The area of the bedroom closet is 48 ft². This means that

LW = 48 - - - - - - - -- - - - - - 1

Substituting L = 16 - W into equation 1, it becomes

W(16 - W) = 48

16W - W² = 48

W² - 16W + 48 = 0

W² - 12W - 4W + 48 = 0

W(W - 12) - 4(W - 12) = 0

W - 12 = 0 or W - 4 = 0

W = 12 or W = 4

L = 16 - 4 = 12

If f(x) = 9x – 8, which of the following is the inverse of f(x)?
zheka24 [161]

Answer: f^{-1} (x) = \frac{x+8}{9}

Step-by-step explanation:

f(x) = 9x - 8 , to find the inverse of f(x) , replace f(x) with y , then the equation becomes

y = 9x - 8 , then make x , the subject of the formula ,

9x = y + 8

x = \frac{y+8}{9}

Finally , replace x , with f^{-1} (x) and y with x  , so we have

f^{-1} (x) = \frac{x+8}{9}

How to solve this elimination
aleksandrvk [35]
Firstly you have to reduce the 4 variables to a double system of equation with only 2 variables.

Let's say, first we have to eliminate Z:
Take 1st & 3rd equation & multiply each term of the 1st by (- 1). One done you add up the 1st & the 3rd & you will get:
5W - 4x + 2y = - 18
Follow the same methodology to find another equation without z. Once done you will have a system of 2 equation with 2 variable easy to solve,

At the end you will find:
w = -3
x = -2
y = -1
z = 3
