There is an app called socratic, also if this assignment goes with a text book there is an app called sladder that has all textbook answers with work
Answer:
E = 96
Step-by-step explanation:
Given the following data;
E = kf .......equation 1.
When E = 24, f = 6
First of all, we would have to find the constant k;
Substituting the values into eqn 1, we have;
24 = k6
k = 24/6
k = 4
To find the value of E, when f = 24
E = kf
Substituting into the equation, we have;
E = 4*24
E = 96
The answer is: 
The explanation is shown below:
1. To solve this problem you must apply the following proccedure:
2. You have the logarithm expression:

3. First, you must apply the following property:

4. Therefore, you have:

5. By applying logarithm on both sides, you have:

6. By applying the property
:

7. Solve for x:

Answer: B) neither
================================================
Let's isolate y in the first equation. This way we can find the slope.
x-2y = 4
-2y = 4-x
-2y = -x+4
y = (-x+4)/(-2)
y = -x/(-2) + 4/(-2)
y = (1/2)x - 2
This matches with y = mx+b form with m = 1/2 being the slope.
The slope of y = 2x-2 is m = 2
------------------------------
The slope of the first line is 1/2 and the slope of the second line is 2.
Since the two slopes (1/2 and 2) are not equal, this means the lines are not parallel.
Also, the two slopes do not multiply to -1, so the lines aren't perpendicular either.
This leads to B) neither as the final answer.
You ignore the 0's for now and think of 3 x 8 instead
3 x 8 = 24
with the answer of 24, you would now attach the two 0's
2400
2400 is your answer
