diameter of human hair is around 0.0025cm
in scientific notation it is: 2.5x10^-3
Answer:
2
Step-by-step explanation:
The slope is the rise over the run. 2 simple coordinates I can see is (6,2) and (7,4). I usually like to visualize it instead of actually solving it mathematically. So, we can start at (6,2). The point (6,2) goes up 2 and 1 to the right in order to get (7,4.) So since the slope is rise over run ( y/x) it would be 2/1 because we went 2 up the y axis and 1 to the right of the x axis. So 2/1 is 2. Therefore, 2 is the answer. I'm sorry if my explaining isn't the best... I hope this helps though!!
Answer:
x=-2
y=-3
Step-by-step explanation:
-9x+4y = 6
9x+5y = -33
We will add these together to eliminate x
-9x+4y = 6
9x+5y = -33
----------------
0x +9y =- 27
9y = -27
Divide by 9
9y/9 = -27/9
y =-3
We still need to find x
9x +5y = -33
9x +5(-3) = -33
9x-15 = -33
Add 15 from each side
9x+15-15 =-33+15
9x=-18
Divide by 9
9x/9 = -18/9
x = -2
