Mathematics
1 answer:
pickupchik [31]3 years ago
8 0

Answer:

Step-by-step explanation:

Alright, lets get started.

The given equation is :

e^{3x+6} =8

taking log on both side

lne^{3x+6}=ln8

(3x+6)lne=ln8

Plugging the value of ln e as 1

3x+6=ln8

Subtracting 6 in both sides

3x+6-6=ln8-6

3x=ln8-6

Dividing 3 in both sides

x=\frac{ln8-6}{3}    ........................  Answer

Hope it will help :)

A quadratic equation ax^2+bx+c=0 has -11 and 4 as solutions. Find the values of b and c if the value of a is 1 (hint, use zero f
Alina [70]

Answer:

b = 7, c = -44

Step-by-step explanation:

If the quadratic equation has the solutions -11 and 4, the two factors are:

(x+11)(x-4)=0

Since when we use the zero factor property we get

x+11=0 ⇒ x= -11

x-4=0 ⇒  x=4

Thus, we have used the zero factor property in reverse to find the factorization of the quadratic equation.

Now we develop the multiplications between parenthesis:

(x+11)(x-4)=0\\x^2-4x+11x-44=0\\x^2+7x-44=0

So b is the number that accompanies the x: b = 7

and c is the independent number: c = -44
