Call g the number of girls and b the number of boys.

These are the equations that represent the situation:

1) g = 4 + 2b

2) g/2 - b = 2

To solve it you can multiply the second by 2:

=> 2 { g/2 - b = 2 }

=> g - 2b = 4

As  you can see this equation is equivalent to the first equation, so this system is not determined (it has infinite solutions).

ASAAPPPPPP!!!!! Complete the tables of values
velikii [3]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

a^{-m} ⇔ \frac{1}{a^{m} } and a^{0} = 1

Substitute the values of x into 4^{-x}

x = 0 → 4^{0} = 1 ⇒ a = 1

x = 2 → 4^{-2} = \frac{1}{4^{2} } = \frac{1}{16}, hence

b = \frac{1}{16}

x = 4 → 4^{-4} = \frac{1}{4^{4} } = \frac{1}{256}, hence

c = \frac{1}{256}
