What is the value of x in the equation below?
denis23 [38]

Answer:

Step-by-step explanation:

Alright, lets get started.

The given equation is :

1+2e^{x+1}=9

Subtracting 1 in both sides

1+2e^{x+1}-1=9-1

2e^{x+1}=8

Dividing 2 in both sides

e^{x+1}=\frac{8}{2}

e^{x+1}=4

Taking log on both sides

loge^{(x+1)}=log4

(x+1)loge=log4

Plugging the value of log e as 1

x+1=log4

x=log4-1   ..................... Answer

Hope it will help :)

Please help me ... 6a + 2(c - b) when a = 2, b = 1, and c = 9 I know thë answer but I just need an explanation
Angelina_Jolie [31]

Answer:

Step-by-step explanation:

Let the expression representing a situation is,

y = 6a + 2(c - b)

Where, a, b and c are the constants

If a = 2, b = 1 and c = 9

By substituting these values in the expression,

y = 6(2) + 2(9 - 1)

y = 12 + 16

y = 28

Therefore, for all given values of the constants value of y is 28.
