therefore ur answer is OPTION A 8.889 x 10-6 cm/s
Answer: 8x+24
Step-by-step explanation:
A.
If you multiply the original equation by 3 you get -45x+3y=54, which is the exact same as A, therefore they have infinite solutions.
Answer:
Step-by-step explanation:
No of ways in which 5 cards are chosen is 
No of ways in which at most 4 cards are spades 
Total ways-5 spades
Probability that at most 4 cards are spade 
1. (3,2)....because when finding the slope, we find the the slope of mn and the slope of op are negative reciprocals.
2. y = 5x - 7.....slope here is 5....perpendicular line has a negative reciprocal slope...so the slope has to be -1/5
y= mx + b
slope(m) = -1/5
(-10,3)...x = -10 and y = 3
now we sub and find b, the y int
3 = -1/5(-10) + b
3 = 2 + b
3 - 2= b
1 = b
so ur perpendicular equation is : y = -1/5x + 1
