B) Negative 3/4
The slope of a line is defined as:
Gram and milligram are in the metric system and are for weight. Pound is the United States system and kiloliter measures liquids
Answer:
x=80.8
Step-by-step explanation:
follow BODMAS
2015-(2015÷5(x-5)÷5)=2014
2015-(2015÷5x-25÷5)=2014
2015-(405/x-5)=2014
2015-(405-5x)=2014
2015-405+5x=2014
1610+5x=2014
5x=2014-1610
(5x=404)1/5
x=80.8
Answer:
x = 9/2
Step-by-step explanation:
The outside triangle is also a right triangle, with hypotenuse 8 and side 6.
The missing side can be calculated with pythagoras as:
![\sqrt{8^2-6^2} = \sqrt{28}](https://tex.z-dn.net/?f=%5Csqrt%7B8%5E2-6%5E2%7D%20%3D%20%5Csqrt%7B28%7D)
Now for the vertical line, lets call it y, which is a side for two "back to back" triangles, you can do pythagoras twice:
left triangle:
right triangle: ![y^2 + x^2 = 6^2](https://tex.z-dn.net/?f=y%5E2%20%2B%20x%5E2%20%3D%206%5E2)
Eliminating y², you can solve:
![28 - (8-x)^2 = 36 - x^2](https://tex.z-dn.net/?f=28%20-%20%288-x%29%5E2%20%3D%2036%20-%20x%5E2)
![28 -x^2 + 16x - 64 = 36 - x^2](https://tex.z-dn.net/?f=28%20-x%5E2%20%2B%2016x%20-%2064%20%3D%2036%20-%20x%5E2)
![16x = 36 + 64 - 28](https://tex.z-dn.net/?f=16x%20%3D%2036%20%2B%2064%20-%2028)
![x = \frac92](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac92)
