The answer is 15i radical 6
The initial height is 4
after 2 seconds, the height is 8
Brainliest answer, please?
Answer:
4 I think is the answer
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 <==
Answer:
Step-by-step explanation:
It is a solution because if you plug in 84 for b you get 84/12 = 7
