-3(x-4) > 6(x-1)
-3x +12 > 6x -6
12+6 > 6x+3x
18 > 9x

x < 18/9

x < 2 so from this result the solution set for this inequality dont includes 3 as an element

Trapezoid JKLM is is shown below. What is the length in centimeters, of KL

IrinaVladis [17]

The complete question is:

Trapezoid JKLM is shown below.

What is the length, in centimeters, of KL ?

A. 12 cm

B. 10 cm

C. 9 cm

D. 6 cm

The mentioned figure is attached.

Answer:

$\large\boxed{option\text{ B. }(\overline{KL})=10cm}$

Explanation:

1. KL is the hypotenuse of a right triangle; hence, you can use Pythagora's theorem to find its length.

2. The height 8 cm is one leg of the right triangle.

3. The other leg may be found by difference:

$\overline{ML} -\overline{JK}=15cm-9cm=6cm$

4. Now you can use Pythagora's theorem:

$hypotenuse^2=(leg_1)^2+(leg_2)^2\\ \\ (\overline{KL})^2=(8cm)^2+(6cm)^2\\ \\ (\overline{KL})^2=64cm^2+36cm^2=100cm^2\\ \\ (\overline{KL})=10cm$

Write the inverse function for the function, ƒ(x) = x + 4. Then, find the value of ƒ -1(4). Type your answers in the box.

lesya [120]

The inverse is:

$f^{-1}(x) = x-4$

Further explanation:

Given function

$f(x) = x+4$

Step 1: Replacing f(x) with y

$y = x+4$

Step 2: Replacing x with y and y with x

$x = y+4$

Step 3: Solving the equation for y

$x = y +4\\x -4 = y+4-4\\y = x-4$

Step 4: Replacing y with f-1(x)

$f^{-1}(x) = x-4$

So, the inverse is:

$f^{-1}(x) = x-4$
