Mathematics
1 answer:
Dahasolnce [82]3 years ago
4 0
                                      y = 12(2x - 1)(2x + 7)
                                      y = 12(2x(2x + 7) - 1(2x + 7))
                                      y =12(2x(2x) + 2x(7) - 1(2x) - 1(7))
                                      y = 12(4x² + 14x - 2x - 7)
                                      y = 12(4x² + 12x - 7)
                                      y = 12(4x²) + 12(12x) - 12(7)
                                      y = 48x² + 144x - 84
               -48x² - 144x + y = -84
         -1(-48x² - 144x + y) = -1(-84)
-1(-48x²) + 1(144x) - 1(y) = 84
               48x² + 144x - y = 84

3/2+t=1/2 how to slove
Nataly [62]
First, let's isolate t! Make sure to change your signs when you change from one side of the equation to the other. 

3/2 + t = 1/2
          t = 1/2 - 3/2

Now, we can solve for t!
          
          t = 1/2 - 3/2
          t = -2/2
          t = -1

Hope this helps!

Ugo [173]

Answer:

4

Step-by-step explanation:

There are 4 board members and 3 committee members. You can solve this using combinations:

4C3 = 4!/(3!(4-3)!) = 4!/(3!1!) = 4

You can also solve this by recognizing that since there is one fewer committee spot than there are board members, there will be one possible committee excluding each of the 4 board members.
