A rectangular garden originally measured 5 feet by 10 feet as shown below.a path was created by increasing each side of the orig

kotegsom [21]

The area is given by
A = (5 + 2x) * (10 + 2x) - 50
Rewriting we have:
A = 50 + 10x + 20x + 4x ^ 2 -50
Rewriting we have:
A = 4x ^ 2 + 30x
Substituting the value of the area we have:
54 = 4x ^ 2 + 30x
Rewriting:
4x ^ 2 + 30x - 54 = 0
We look for the roots:
x1 = -9
x2 = 3/2
We take the positive root:
x2 = 3/2
Answer:
the value of x is:
x = 3/2

Leticia charges $8 per hour to babysit. She babysat Friday night for 4 hours,

Dmitriy789 [7]

For this case we have that the variable "x" represents the number of hours that Leticia uses to take care of children on Saturday.

IF on Friday I use 4 hours ($ 8 each) and on Saturday "x" hours ($ 8 each) obtaining a profit of $ 72, we have the following equation:

$8 (4 + x) = 72$

We apply distributive property:

$32 + 8x = 72\\8x = 72-32\\8x = 40\\x = \frac {40} {8}\\x = 5$

So, on Saturday she spent 5 hours.

Answer:

$8 (4 + x) = 72\\x = 5$

Drag each tile to the correct box. Not all tiles will be used.

qaws [65]

Answer:

Inverse of f(x)

$f^{l} (x) = \frac{8 x}{3-x}$

Step-by-step explanation:

<u> Explanation</u>:-

<u>Step(i)</u>:-

Given the function

$f(x) = \frac{3 x}{8+x}$

Given function is one-one and onto function

Hence f(x) is bijection function

$y = f(x) = \frac{3 x}{8+x}$

now cross multiplication, we get

( 8+x)y = 3 x

8 y + x y = 3 x

8 y = 3 x - x y

taking Common 'x' we get

x (3 - y) = 8 y

$x = \frac{8 y}{3-y}$

<u><em>Step(ii)</em></u>:-

The inverse function

$x = \frac{8 y}{3-y} = f^{l}(y)$

The inverse function of x

$f^{l}(x) = \frac{8 x}{3-x}$

<u><em>Final answer</em></u>:-

Inverse of f(x)

$f^{l} (x) = \frac{8 x}{3-x}$
