Answer:
y=1/2x-4
Step-by-step explanation:
2y-x=-8
2y=x-8
y=1/2x-4
Answer:
y= 43
x= 37
Step-by-step explanation:
Legs: (43 x 4) + (37 x 2) = 248
Heads: 43 + 37 = 80
The answer would be D because V= side length times 3
I would have labeled the points as
(x1,y1) = (11,12)
(x2,y2) = (15,16)
then used the formula
m = (y2-y1)/(x2-x1)
However, your idea works as well. I don't see any errors with your steps. Nice work.
Answer: +/- 0.018
All you have to do is plug the known values into the equation and evaluate it.
First, do the work under the square root sign. 0.77(1-0.77) / 2100 gives you a very small number. If you take the square root of that, you will have 0.0091.
The last step is to just multiply that by 2 and you will have 0.018
