What is the value of x?

skelet666 [1.2K]

Answer:

x = 20

Step-by-step explanation:

Since ΔACB ≅ ΔDCE then ∠A ≅ ∠D, that is

3x - 10 = 2x + 10 ( subtract 2x from both sides )

x - 10 = 10 ( add 10 to both sides )

x = 20

Using the graph, what does f(8) equal?<br> PLEASE I NEED SO MUCH HELP!!

Shtirlitz [24]

Answer:

Step-by-step explanation:

The question is not terrifically worded. What it means is "What is the y value when x = 8" That's what f(8) conveys to you.

The answer (though zero is not marked and should be) is 1 unit above 0.

The answer is f(8) = 1 He's heading back.

BRAINLIEST ANSWER THIS IS URGENT PLEASE HURRY. ANSWER ALL THE BLANK BOXES.

shusha [124]

The answers are:

1) $x$

2) $x$

3) $\frac{ln(x+4)}{2}$

The explanation for this answer is shown below.

1. To solve this problem you must apply the following proccedure:

2. You have the function $f(x)=e^{2x}-4\\ y=e^{2x}-4$

3. You must switch $x$ and $y$ and then solve for $x$ :

$x=e^{2y}-4\\ x+4=e^{2x}\\ ln(x+4)=2y\\ y=\frac{ln(x+4)}{2}$

4. Finally, you obtain:

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