10x + 1 = 2(3× + 5) - 1
MArishka [77]

Answer:

x = 2

Step-by-step explanation:

10x + 1 = 2(3x + 5) - 1

  1. mutlipy the 2 to the 3x and the 5
  2. you should get 10x + 1 = 6x + 10 - 1
  3. now you have to add the combine terms
  4. so it will now be 10x + 1 = 6x + 9
  5. now you.have to get the x's on one side and the constants (numbers alone) on the other side
  6. so you can subtract the 6x on both sides
  7. once you do that you wil get 4x + 1 = 9
  8. After you get this equation you will have to subtract the one from both sides.
  9. you will get 4x = 8
  10. All you have to do it divide 4 on both sides. Your final answer is x = 2.

Explain the difference between exponential growth and exponential decay
alexdok [17]
Exponential growth is the function
y =  a^{x} , a\ \textgreater \ 1
Exponential decay is the function
y = a^{x} , 0\ \textless \ a\ \textless \ 1
So, the basic difference is that in growth the base is more than 1, and in decay the base is more than 0 but less than 1.
