kiruha [24]

Answer:

The quantity of board which Mr. Stevens need to buy is 22.4 meters

Step-by-step explanation:

Given as :

The length of board = 6.9 meters

The width of board = 4.3 meters

Let The measure of new board = x meter

Now,

The measure of new board = The perimeter of board

∵ The board is of rectangle figure

As, The perimeter of rectangular board = 2 × Length + 2 × width

So, The measure of new board = 2 × Length + 2 × width

or, x = 2 × 6.9 + 2 × 4.3

or, x = 13.8 + 8.6

or, x = 22.4 meters

So, The measure of new board = x = 22.4 meters

Hence The quantity of board which Mr. Stevens need to buy is 22.4 meters Answer

Step 1: 12x – 15 – 12x = 7x + 20

stealth61 [152]

Step-by-step explanation:

step 1. 12x - 15 - 12x = 7x + 20

step 2. 12x - 12x - 15 = 7x + 20 (grouping of terms)

step 3. -15 = 7x + 20 (adding like terms)

step 4. -35 = 7x (subtract 20 from both sides)

step 5. this step is incorrect.

step 6. -5 = x ( divide both sides by 7)

step 7. x = -5 (put the variable first).

A 100 gallon fish tank fills at a rate of x gallons per minute. The tank has already been filling for 5 minutes. the function f(

Alexxx [7]

Answer:

Shifted 5 unit right side then stretched vertically by the factor 100

Step-by-step explanation:

Here, parent function,

$f(x)=\frac{1}{x}$

Transformed function,

$f(x) = \frac{100}{x-5}$

Since, if a function f(x) gives cf(x), where c is any number,

Then the function was vertically stretched by factor c,

While, the function gives f(x-c),

Then the function was shifted c unit right.

Hence, the graph of $f(x)=\frac{1}{x}$ was shifted 5 unit right side then stretched vertically by the factor 100 to create the graph of $f(x)=\frac{100}{x-5}$
