Point T is the midpoint of J and H.
x-coordinate is 0 for the three points.
y-coordinate of T is in the middle of the y-coordinate of J and the y-coordinate of H. So, y-coordinate of H has to be 6, because (6+2)/2=8/2=4.
Then point H is (0,6).
Answer:
Step-by-step explanation:
Assuming the order in which he answers the questions matter the answer is the number of permutations of 8 in 10.
This is 10! / (10-8)!
= 1,814.400.
If the order does not matter then the answer is the number of combinations of 8 from 10:
This is 10!/8!*2!
= 45.
Answer:
x = -9, -3
Step-by-step explanation:
x^2 + 12x + 27 = 0
We need 2 numbers whose product is + 27 and whose sum is + 12. These are 3 and 9. So the factors are:-
(x + 3)(x + 9) and this = 0
So (x + 3) = 0 or x + 9 = 0
x = -3 , -9
