Step-by-step explanation:

Step 1: Define

$\displaystyle f(x) = 2(4)^x\\f(-2) \ is \ x = -2$

Step 2: Evaluate

Substitute in x: $\displaystyle f(-2) = 2(4)^{-2}$
Exponents: $\displaystyle f(-2) = 2(\frac{1}{16})$
Multiply: $\displaystyle f(-2) = \frac{1}{8}$

An isosceles triangle has two sides of equal length. The third side is five less than twice the length of one of the other sides

4vir4ik [10]

Answer:

Step-by-step explanation:

We can set up a systems of equations to find the value of the third side.

Let's assume that $x$ is the length of both sides 1 and 2. Let's also assume that $y$ is the length of the third side.

We know that $x + x + y = 23$ , and looking at the first clue we can make the equation $y = 2x-5$ .

We can substitute y into the equation $x + x + y = 23$ .

$x + x + (2x-5) = 23\\\\2x + 2x-5 = 23\\4x-5 = 23\\4x = 28\\x = 7$

So the length of the side that is the same as the second is 7.

Now we can plug this into the equation $y = 2x-5$ to find $y$ .

$y = 2(7) - 5\\\\y = 14-5\\\\y = 9$

Hope this helped!
