Use the power rule
  d(x^n)/dx = n·x^(n-1)
to form the derivative.
  f'(x) = 4·2x -4
  f'(x) = 8x - 4

Now, substitute "a" for "x" to find f'(a):
  f'(a) = 8a - 4

Answer:

x=13

z=84

Step-by-step explanation:

The intersection of two of these lines actually have relationships. The two angles that have the variable x both add up to 180 degrees since we assume for them to be a straight line, and the angle with '11x-59' is equal to Z since they are vertical from each other.

Knowing this, we can add the two equations together and equal it to 180. This is to give us the variable x.

(11x-59)+(13x-73)=180       (always use parenthesis!)

24x-132=180                     (combine like terms)

24x=312

x=13                                   (isolate x)

We now know that the x stands for 13, but we are not done. By plugging in the variable x in for the equation 11x-59, we can find the value of z since they are vertical angles.

11(13)-59=84

z=84

Answer:

1. -5

2. 0

Step-by-step explanation:

<em>1.</em> Distribute the Negative Sign:

=a−2a+−1(3a−(4a−5))

=a+−2a+−1(3a)+−1(−4a)+(−1)(5)

=a+−2a+−3a+4a+−5

Combine Like Terms:

=a+−2a+−3a+4a+−5

=(a+−2a+−3a+4a)+(−5)

Answer:

=−5

<em>2. </em>Distribute:

=(13)(5)+(13)(−t)+−5+t+(−12)(5)+(−12)(−t)

=65+−13t+−5+t+−60+12t

Combine Like Terms:

=65+−13t+−5+t+−60+12t

=(−13t+t+12t)+(65+−5+−60)

Answer:

=0
