Answer:

x = 1/3 ln(2)

Step-by-step explanation:

e^(3x)+6=8

Subtract 6 from each side

e^(3x)+6-6=8-6

e^(3x) = 2

Take the natural log of each side

ln (e ^3x) = ln (2)

3x = ln(2)

Divide by 3

3x/3 = 1/3 ln(2)

x = 1/3 ln(2)

Answer:

2/3

Step-by-step explanation:

I'm not sure of the e is actually there, so I'm answering without it being there.

3x+6=8

3x=8-6

3x=2

x=2/3

Hope the working helped you understand what was going on, if not, I'll edit and give a more detailed explanation. Good luck with homework :)

Solve the equation 7=4s+19
lyudmila [28]

Isolate the s. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

Subtract 19 from both sides

7 (-19) = 4s + 19 (-19)

7 - 19 = 4s

-12 = 4s

Isolate the s. Divide 4 from both sides

-12/4 = 4s/4

s = -12/4

s = -3

-3 is your answer for s

hope this helps

(Photo attached) Trig question. Please explain and thanks in advance! :)
Gennadij [26K]

Answer:

  x ≈ 0.1459

Step-by-step explanation:

Since you only want a small positive solution, you can use the arcsine function to find it.

 6sin(5x) = 4

 sin(5x) = 4/6 = 2/3

 5x = arcsin(2/3)

  x = arcsin(2/3)/5

  x ≈ 0.1459

_____

A graphing calculator can find the solution easily. It is often easiest to rewrite the equation so you're looking for a solution that makes the value zero. Here, subtracting 4 from both sides does that.
