It is evident that you need to find the solution of the system, if it exists.

Let's work the equations.

The second equation (which corresponds correctly to the second statement) is:

g/2 - b = 2, which you can be transformed in this way:

1) Multiply by 2 => g - 2b = 4

2)  Transpose - 2b => g = 4 + 2b.

Now you can see that this equation is the same than the firs equation, which means that the second statement does not provide any new information.

Mathematically, this is a system with infinite solutions, and you cannot determine the number of boys or girls without more information which provides and independent equation.

Answer: there are infinite solutions to the system.

The function, f(x) = x2, is transformed to obtain function g as shown.
poizon [28]

It is the graph of f(x) = x^2 vertically compressed, and then translated 3 units up and 5 units to the right.

<h3>Transformation techniques</h3>

Transformation is a process of changing the size and shape of an object. The given graph is a graph of quadratic function with parent function x².

According to the graph shown the resulting parent function has been shifted horizontally to the right by 5 units to produce g(x) = f(x) - 5
