Tatiana [17]

If a $24 dvd is marked down by 30% then the cost of the dvd would be 70% of the original cost. 100% - 30% = 70%

70% of 24 can be expressed as 0.7 x 24.

The answer is $16.80.

Hope this helps :)

Answer:

  f(g(x)) = -3x^2 -2x -3

Step-by-step explanation:

<u>Given</u>:

  f(x) = -x-7

  g(x) = 3x^2 +2x -4

<u>Find</u>:

  f(g(x))

<u>Solution</u>:

Substitute per the function definitions.

  f(g(x)) = f(3x^2 +2x -4) = -(3x^2 +2x -4) -7

  f(g(x)) = -3x^2 -2x -3

Find x.______________a0
velikii [3]

Answer:

x=4

Step-by-step explanation:

Before we find x, we need to set up this triangle a little more. We need to find the triangle's altitude before we can solve for x. We will use the heartbeat method to find the altitude.

Let altitude = y; solve for y:

\frac{2}{y}=\frac{y}{6}

y^2=12

y=\sqrt{12}

y=2\sqrt{3}

Now that we know the altitude, we can use the Pythagorean Theorem to find the hypotenuse (x).

a^2+b^2=c^2

2^2+(2\sqrt{3})^2=c^2

4+12=c^2

c^2=16

c=4

Since c and x are the same; c is just the hypotenuse in the Pythagorean Theorem.

x=4
