Hey!
This could be rewritten as:
2x + 1 + 5x
We can add like terms together:
7x + 1
What are the answer choices
.
The equation is:
[e^x] [e^(2x)] = 4
1) Applying property of multiplication of powers wiith same base =>
e ^ (x + 2x) = 4
=> e ^ (3x) = 4
2) Applying logarigth properties
3x = ln(4)
=> x = ln(4) / 3 ≈ 1.38629 / 3 ≈ 0.4621
Answer: x = ln(4) / 3 ≈ 0.4621
Fourth one since x is 2 and the y is 1
Its a correlation not a causality, therefore the answer is A
