The graphs of linear functions f and g are shown. Enter the solution to the equation f(x)=g(x).
-Dominant- [34]
<h3>Answer:  x = -3</h3>

The two diagonal lines cross at (-3,5). We only need to worry about the x coordinate here, so x = -3 is what we're after. If x = -3, then f(x) and g(x) have the same y output meaning f(x) = g(x). That y output is y = 5.

How many ways can we award a 1st, 2nd and 3rd place prize among eight contestants?
trasher [3.6K]

Answer:

Total number of ways are 336.

Step-by-step explanation:

It is required to find the number of ways in which we can award a 1st, 2nd and 3rd place prize among eight contestants. It means we need to find the number of permutations. We need to find ^8P_3.

Here, r = 3

So,

^nP_r=\dfrac{n!}{(n-r)!}\\\\^8P_3=\dfrac{8!}{(8-3)!}\\\\^8P_3=\dfrac{8!}{5!}\\\\^8P_3=\dfrac{8\times 7\times 6\times 5!}{5!}\\\\^8P_3=336

So, there are 336 ways.
