First we need to find the slope of the original equation
2x - 3y = 3
-3y = -2x + 3
y = 2/3x - 1....the slope here is 2/3.
However, we need a perpendicular line...so we need to use the negative reciprocal slope. All that means is flip the slope and change the sign.
slope 2/3.....flip.....3/2....change the sign...-3/2.
so our perpendicular line will need a slope of -3/2.
y = mx + b
slope(m) = -3/2
(-8,2)...x = -8 and y = 2
now we sub and solve for b, the y int
2 = -3/2(-8) + b
2 = 12 + b
2 - 12 = b
-10 = b
so our perpendicular line is : y = -3/2x - 10
Answer:
there are 20 different combinations if that was the question.
Step-by-step explanation:
Formula :
Combination(event 1) times Combinations (Event2)
Answer:
39.7
Step-by-step explanation:
first must calculate the length of AB and BC
AB = 16.43
CB= 12.216
then perimeter : Perimeter of a triangle = sum of all three sides
(6-1)x-2(8y)
6x-1x-16y
5x-16y
