Step-by-step explanation:
This means that if a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m. For example, we found that the slope of the line y = (1/2)x + 3 is 1/2. Thus any line that is perpendicular to this line would have slope -2 /1 = -2.
What place? And I will be glad to help :)
If it is y = love 2x:
<span>y = log_2 (x) =====> when x = 1/2
y = log_2 (1/2)
y = -1 ======> (1/2 , -1)
y = log_2 (x) =====> when x = 1
y = log_2 (1)
y = 0 ======> (1 , 0)
y = log_2 (x) =====> when x = 2
y = log_2 (2)
y = 1 ======> (2 , 1)
y = log_2 (x) =====> when x = 4
y = log_2 (4)
y = 2 ======> (4 , 2)
y = log_2 (x) =====> when x = 8
y = log_2 (8)
y = 3 ======> (8 , 3)
y = log_2 (x) =====> when x = 16
y = log_2 (16)
y = 4 ======> (16 , 4) </span>
43/9 = 4.77777777778
That is because only the most 9's that could fit into 43 is 4 which is 9 x 4 = 36. I can't really show the work, but I think Khan Academy would be a great help!
