The answer should be B. 8x-10
Answer: The cable 137 meters from the top of the tower to the anchor point.
Your task is to convert 12m/s into km/min
to get kilometers from meters we need to divide by 1000 and to get minutes from seconds we need to multiply 12 by 60. The reason why we are multiplying is because minutes are bellow / sign, so dividing divisor is equivalent to multiplying entire number.
That means that the answer is converting seconds to minutes and meters to kilometers
Hello from MrBillDoesMath!
Answer: NO points of intersection. The two lines are parallel
Discussion:
Rewrite the equations so the variables and constants line up vertically
x - 2y + 8 = 0
x - 2y -6 = 0 (I added "x" to both sides of the second equation)
Subtract the bottom equation from the the top one:
(x - 2y + 8) - ( x - 2y -6) = 0 or
x - 2y + 8 - x + 2y + 6 = 0 or
(x-x) + (-2y +2y) + (8 + 6) = 0 or
0 + 0 + 14 = 0
14 = 0 !
No solution exists. (Another approach: What is the slope of each line? Hint: 1/2. Since the slopes are the same the lines are parallel and have no points of intersection)
Thank you,
MrB
