Answer: The CORRECT answer is <u>C: log2(x-4)=3</u>

Nadya [2.5K]3 years ago

Answer:

log_{3}(x-4)= 3log_{3}(2)

Step-by-step explanation:

The given equation is:

x-4=2^{3}

We have to find the logarithmic equation with same solution as the given equation.

If we take the log of both sides, we can get a logarithmic equation. Since the log operation is applied to both sides the solution of the equation will stay the same.

Taking the logarithm to the base 3 of both sides, we get:

log_{3}(x-4)= log_{3}(2)^{3}\\\\ log_{3}(x-4)= 3log_{3}(2)

flying with wind, a small plane flew 410 mi in 2 h. Flying against the wind, the plane could fly only 380 mi in the same amount
Thepotemich [5.8K]

Answer:

197.5 mph.

Step-by-step explanation:

If flying with wind a small plane flew at 410 miles and 380 miles then the next step is to divide both speeds by two. This way you get the mph. So now it is 205 mph and 190 mph. Now we find the average of these two numbers and you get 197.5 mph.

Simplify<br>1)5x+3=x+13<br>2)5/2x-1/X =1/6​
Artyom0805 [142]

Step-by-step explanation (Question 1):        

<u>Step 1: (Question 1): Subtract x from both sides.</u>

5x+3=x+13

5x+3−x=x+13−x

4x+3=13

<u>Step 2: (Question 1): Subtract 3 from both sides.</u>

4x+3−3=13−3

4x=10

<u>Step 3: (Question 1): Divide both sides by 4.</u>

4x/4 = 10/4

FIRST ANSWER: x = 5/2

Step-by-step explanation (Question 2):      

<u>Step 1: (Question 2): Multiply by LCM</u>

15x^2 - 6 = x

<u>Step 2: (Question 2): Solve 15x^2</u>

15x^2 - 6 = x:

x = 2/3

x = -3/5

<u>Step 3: (Question 2): Solve</u>

ANSWER: x=0.666667 or x=−0.6

See Attachment 1 for question 1 steps (FULL)

See Attachment 2 for question 2 steps (FULL)

Answer:    

1)   x = 5/2

2)  x=0.666667 or x=−0.6

 

Hope this helps.
