For f(-2), x will equal -2.
Plug the x-value into the equation:

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):

Solve the problem:

f(-2) will equal
1/2.
Answer:
512cm^2
Step-by-step explanation:
Let's imagine cutting the square down that diagonal. Now, we have two isosceles right triangles with a hypotenuse with length 32cm. Let's take one of those triangles for now and focus on it. Let's give the one of the legs of a triangle some length x. Since both legs are the same length, by the Pythagorean theorem:

Since this leg makes up one side of the square, we can use it to calculate the area of the square, which is just the side length squared:

Answer:
6 $10 bills
Step-by-step explanation:
First you have to make a system of equations like such
5x + 10y = 150
x + y = 24
Now you can use any strategy to simplify it but I'll use multiplication and the subtraction:
5x + 10y = 150 - 5x + 5y = 120 = 5y = 30 this simplified is y = 6. You then substitute 6 for y in either equation. x + 6 = 24 and make it on opposite sides. x = 18.
So 18 $5 bills and 6 $10 bills
