Answer: 9/7
Step-by-step explanation:
(7/9)^-1 means you have to find the reciprocal, which is 9/7
The line x = 2 is vertical. This means that ab is horizontal since they are perpendicular. So, the y coordinate of b must be 1.
If x = 2 bisects ab, then a and b are equal distances from x = 2.
a is 2 - (-4) = 6 units away from x = 2, so b must be 6 units away in the other direction. The x coordinate of b is 6 + 2 = 8.
The coordinate of b is (8, 1)
Answer:
the domain(s) are 7, 5,-3, and -6.
Step-by-step explanation:
the domain is the x which can repeat. the range is the y which can't repeat.
Mean = sum/N
7 = 42/N
N = 42/7 . . . . . multiply by N/7
N = 6
