Answer:
k = 17
Step-by-step explanation:
slope = (y-y') / (x-x')
slope A = (9 + 1) / (-1 + 3) = 10/2 = 5
slope B = (4 - 1) / (k + 2) = 3 / (k + 2)
perpendicular: slope B = - 1 / slope A
3 / (k + 2) = - 1/5
2 + k = - 5 x 3 = - 15
k = 17
0.05 because 5 is bigger than 4 plus 4 is negative
Answer: 0
Step-by-step explanation:
So the slope of a line is equal to rise over run, or the change in x over the change in y. We can solve for the change in x and the change in y by finding their differences. For the math, we use the formulas y2 - y1/x2 - x1. Filling in this formula we get, (5-5)/(3-13), which is equal to 0/10. Because 0 divided by anything is 0, the answer here is 0.
You would multiply by the reciprocal (flip the fraction)
5/3 * 24 = 40
b = 40
Answer:
Step-by-step explanation:
I assume you are talking about square roots when you say root...
Sqrt(-9) = 3i
Sqrt(-12) = 2Sqrt(3)i
Complex number is 3 + 2Sqrt(3) i
