Answer: x= -10 and Y=-20
Step-by-step explanation:
If y is equal to 2x that mean you need to substitute Y=5x+30 like this 2x=5x+30
One way to approach this is to find (g o f)(x) first and then to replace x by -7:
g( f(x) ) = (x^2+6) + 8/(x^2+6)
Now replace x with -7. We get: ( g o f )(-7) = 49+6+8 / (49+6), or
= 55 + 8 / 55, or 55 8/55 (ans.)
<h3>
Answer: 10,080</h3>
Explanation:
There are 8 letters so there are 8! = 8*7*6*5*4*3*2*1 = 40,320 permutations of those letters. However, the letters "O" and "L" show up twice each, so we must divide by 2! = 2*1 = 2 for each instance this happens.
So,
(8!)/(2!*2!) = (40,320)/(2*2) = (40,320)/4 = 10,080
is the number of ways to arrange the letters of "football".
The reason we divide by 2 for each instance of a duplicate letter is because we can't tell the difference between the two "O"s or the two "L"s. If there was a way to distinguish between them, then we wouldnt have to divide by 2.
Answer:
-5, 6 when you reflect over the x axis you have to flip the sign of the y point.
