Answer:
Domain: X is an element of real number
It is a function
Step-by-step explanation:
x is an element of all real numbers
y=5x has a one to one relation. It is a function
Answer:
y = (2x + 3)(2x + 3) = (2x + 3)²
Step-by-step explanation:
We are given a quadratic function and we have to write it in factored form.
y = 9 + 12x + 4x²
y = 4x² + 12x + 9
We can break the mid-term in such a way that when they are multiplied, the factors give a product of 36x² and when added, they give a result of 12x, as show below:
y = 4x² + 6x + 6x + 9
Taking 2x common from the first two variables and 3 from the second two
y = 2x(2x + 3) + 3(2x + 3)
Taking 2x+3 common
y = (2x + 3)(2x + 3) = (2x + 3)²
Let
x-------> the numbers of blue beads
y-------> the numbers of white beads
we know that
--------> equation 
--------> equation 
Substitute equation in equation
Find the value of x
therefore
the answer is
the numbers of blue beads is
