What output is twice the sum of the input 3 and 4
Andreas93 [3]

Answer:

Required output = 14

Step-by-step explanation:

Sum of the input 3 and 4 = 3 + 4

Twice the sum means two times.

So, to find twice the sum of the input 3 and 4, we need to multiply the sum by 2.

2(3 + 4)

Perform the addition inside the parentheses.

2(3 + 4) = 2(7)

Now, multiply.

2(3 + 4) = 14

Hence, required output = 14

Solving equations with variables on both sides <br><br><br> 7+9x=6x-2
katrin2010 [14]

Answer:

Here

Step-by-step explanation:

We move all terms to the left:

7+9x-(6x-2)=0

We get rid of parentheses

9x-6x+2+7=0

We add all the numbers together, and all the variables

3x+9=0

We move all terms containing x to the left, all other terms to the right

3x=-9

x=-9/3

x=-3

Somebody, please help
SashulF [63]
F(x) can be written as:
f(x) = Asin(2x); where A is the amplitude and the period of the function is half that of a normal sin function.
f(π/4) = 4
4 = Asin(2(π/4))
4 = Asin(π/2)
A = 4
Amplitude of g(x) = 1/2 * amplitude of f(x)
A for g(x) = 2
g(x) = 2sin(x)
