Answer:

GH = 15

Step-by-step explanation:

In a trapezoid, the length of the median is one-half the sum of the lengths of the bases. Therefore:

9x - 3 =  \frac{1}{2} (19 + 5x + 1)

18x - 6 = 5x + 20

13x = 26

x = 2

9(2) -  3 = 18 - 3 = 15

Simplify the expression below.
Ostrovityanka [42]

Answer: OPTION C.

Step-by-step explanation:

Given the following expression:

4x(3x- 7) - 19x^2

You can simplify this expression applying these steps:

First step: You must apply Distributive property:

=12x^2-28x-19x^2

Second step: You need to add the like terms.

Then, you get:

=-7x^2-28x

Find the function !!! 10 points - Help needed!
Arte-miy333 [17]
<h2>Hello!</h2>

The answer is:

The first option,

f^{-1}(x)=\frac{x-2}{4}

<h2>Why?</h2>

To find the inverse of a function, we need to rewrite the variable "x" with "y" and the variable "y" with "x", and then, isolate "y".

We are given the function:

f(x)=4x+2

Write "f(x)" is equal to write "y", so:

y=4x+2

Now, finding the inverse, we have:

y=4x+2\\x=4y+2\\x-2=4y\\y=\frac{x-2}{4}

Hence, we have that the answer is the first option,

f^{-1}(x)=\frac{x-2}{4}

Have a nice day!
