Answer:
2/9
Step-by-step explanation:
3x - 2y = 7
-2y = -3x + 7
y = 3/2x - 7/2....slope of this line is 3/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -2/3 (see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = -2/3
(-3,-2).....x = -3 and y = -2
now we sub and find b, the y int
-2 = -2/3(-3) = b
-2 = 2 + b
-2 - 2 = b
-4 = b
so ur perpendicular equation is : y = -2/3x - 4 <==
Hi Brainiac
2/5 + p = 4/5 + 3/5 p
Simplify
p + 2/5 = 3/5 p + 4/5
Subtract 3/5p from both sides
p + 2/5 -3/5p = 3/5p + 4/5 -3/5 p
2/5 p + 2/5 =4/5
Subtract 2/5 from both sides
2/5 p +2/5 -2/5 = 4/5 -2/5
2/5 p = 2/5
Divide both sides by 2/5
2/5 p / 2/5 = 2/5 /2/5
p = 1
I hope that's help:)
