Answer:
The answer is C.
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=(-12)-13/2-7
m=-25/-5
m=5
The recipricol of -2/9 is 9/2, or 4 1/2
remember to change the sign (forgot to myself)
hope this helps
If we're only counting 5 vowels (A, E, I, O, U) and 20 consonants (everything else, minus T), then there are
![\dbinom52=\dfrac{5!}{2!(5-2)!}=10](https://tex.z-dn.net/?f=%5Cdbinom52%3D%5Cdfrac%7B5%21%7D%7B2%21%285-2%29%21%7D%3D10)
ways of picking the vowels, and
![\dbinom{20}2=\dfrac{20!}{2!(20-2)!}=190](https://tex.z-dn.net/?f=%5Cdbinom%7B20%7D2%3D%5Cdfrac%7B20%21%7D%7B2%21%2820-2%29%21%7D%3D190)
ways of picking the consonants.
We want the word to start with T, and we'll allow any arrangement of the other 4 letters, so that the total number of words is
![4!\dbinom52\dbinom{20}2=\boxed{45,600}](https://tex.z-dn.net/?f=4%21%5Cdbinom52%5Cdbinom%7B20%7D2%3D%5Cboxed%7B45%2C600%7D)
Keep in mind that this means words like TRIES and TIRES are treated as different.
