What are the zeros for both functions

Mathematics
1 answer:
sammy [17]3 years ago
5 0

Answer:

the zero of a function is the value of x which makes the final value zero

First Equation:

So let 25 - 2x equal to 0

<em>25 - 2x = 0</em>

x = 12.5

Second Equation:

Let 2x² - 11x - 6 equal to zero

<em>2x² - 11x - 6 = 0 </em>

<em>2x² - 12x + x - 6 = 0 </em><em>(Splitting the middle term)</em>

<em>2x(x - 6) + 1(x - 6) = 0</em>

<em>(2x + 1) (x - 6) = 0</em>

So we can transpose either one of the brackets below the zero

(2x + 1) = 0                 or             (x-6) = 0

x = -1/2                      or             x = 6

there are 18 black socks and 12 Navy socks in your drawer the room is dark and you cannot turn on the light what is the least nu
Natasha_Volkova [10]

Answer:

3/5

Step-by-step explanation:

To have the best chance of pulling a pair with the same color you should try to get a pair of black socks. There is a 3/5 chance of pulling a black sock so this means for every 5 socks you pull you get 3 black socks or 2 navy socks. Either way you will get a pair of socks with the same color. (Double check to make sure I'm correct)
