Answer:

The value of the function  (f + g)(x) is 3^{x}+12x -4.

Option (D) is correct .

Step-by-step explanation:

As given the equation in the question be as follow.

f(x) = 3^{x} + 10x

g(x) = 2x - 4

Thus

(f + g)(x) = f(x) + g(x)

(f + g)(x)= 3^{x}+10x +2x -4

Simplify the above

(f + g)(x)= 3^{x}+12x -4

Therefore the value of the function  (f + g)(x) is 3^{x}+12x -4.

Option (D) is correct .

Answer:

The Answer is D

Step-by-step explanation:

All you do is add both equations 3^x+10x+2x-4

then you add the like varibles which is 10x+2x=12x

So, the answer is 3^x+12x-4

What is the answer to this question
krek1111 [17]

The answer is B. x = 29

Here's how I solved for x.

Step 1: Simplify x + -21 to x = 21. Which leaves us with x - 21 = 8

Step 2: Add 21 to both sides. Which leaves us with x = 8 + 21

Step 3: Add 8 + 21 to get your answer: x = 29

What is the slope of (0,0) (2,3)
Virty [35]

Answer:

3/2

Step-by-step explanation:

Para hallar la pendiente de dicha recta formada por dos puntos procederemos a usar la siguiente ecuación

m=y2-y1/x2-x1

Donde (0,0) ---->(x1,y1)           (2,3)------>(x2,y2)

Remplazando x1,x2,y1,y2

m=3-0/2-0 = 3/2

De tal manera la m=3/2

What are the roots of the equation x^4- 4x^3=6x^2- 12x. Using a graphing calculator and system of roots.
Vesna [10]

I don't have a graphing calculator and I don't know what the system of roots is.


But I can solve this anyway.


x^4 - 4x^3 - 6x^2 + 12 x = 0


x(x^3 - 4x^2 - 6x + 12) = 0


So x = 0 is a root and we have a cubic equation to solve.


In school the best way to solve cubic equations is to just try some small numbers; teachers seldom venture beyond 1, -1, 2 or -2 as roots. I guess a graphing calculator saves us the search.


Here we see x=-2 is a root; (-2)^3 - 4(-2)^2 - 6(-2) + 12 = -8 - 16 + 12 + 12 = 0.


So, continuing our factoring, x+2 is a factor, and we divide to get the other factor


        x^2 - 6x + 6

x+2 | x^3 - 4x^2 - 6x + 12

         x^3 + 2x^2

                 -6x^2 - 6x

                 - 6x^2 - 12 x

                               6x + 12

So fully factored we have


0 = x(x+2)( x^2 - 6x +6 )


There's a little shortcut I call the Shakespeare Quadratic Formula (2b or -2b) which works when the linear term is even:


x^2 - 2bx + c \textrm{ has zeros } x =b \pm \sqrt{b^2-c}


Here that means we have two additional roots,


x = 3 \pm \sqrt{3^2-6} = 3 \pm \sqrt{3}


Full set of roots:


x = 0 \textrm{ or } -2  \textrm{ or } 3 + \sqrt{3}  \textrm{ or } 3 - \sqrt{3}
