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
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
Answer:
Any rational number
Step-by-step explanation:
A <em>rational number</em> is a number obtained by dividing two integers.
Thus, 1/3 is a rational number.
You can add <em>any rational number</em> to 1/3 and the sum will be a rational number.
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)
