Line joining (-3, -1) and (1/2, 2)
Point point form for a line is
(c-a)(y-b) = (d-b)(x-a)
(1/2 - - 3)(y - -1) = (2 - -1)(x - -3)
(7/2)(y+1)=3(x+3)
7(y+1)=6(x+3)
7 - 6(3) = 6x - 7y
6x - 7y = -11
Answer: second choice, 6x - 7y = -11
Answer:
B is correct
Step-by-step explanation:
I think you don't need a calculator here. :) Try to figure out next time!
Answer:
5 1/7 or 36/7
Step-by-step explanation:
11 8/7+3 5/1-x=15
12 1/7+8-x=15
12 1/7+8-15=x
20 1/7-15=x
5 1/7=x
You have to calculate how many combinations of 6 people can be chosen from 11. The formula for this is:
n! / [r! * (n-r)!]
combinations = 11! / [6! * 5!] =
11 * 10 * 9 * 8 * 7 / 5 * 4 * 3 * 2 *1 =
11 * 3 * 2 * 7 =
462 Combinations

No it is not an equivalent ratio
