During the 2007 baseball season, Wade was up to bat 10 more times than

bearhunter [10]

Answer:

The number of times Ellis get to bat is 558.

Step-by-step explanation:

Here, let us assume the number of times Ellis bat = m

So, the number of times Dwight bat = 17 times fewer than Ellis

= m - 17

Also, number of times Wade got to bat = 10 more times than Dwight

= ( m- 17 )+ 10

Total number of bat times = 1650

So, the number of times ( Wade + Dwight + Ellis) bat together = 1650

⇒ ( m- 17 )+ 10 + (m - 17) + m = 1650

or, 3 m - 34 + 10 = 1650

or, 3 m = 1674

⇒ m = 1674/3 = 558 , or m = 558

Hence, the number of times Ellis get to bat = m = 558.

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:

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