Answer:
The answers would be 9 and 1.
Step-by-step explanation:
x= 5±√16 can be separated into two equations.
x=5+√16 and x=5-√16
1. 5+√16 can be solved by simplify √16, which is 4. So then it would become 5+4 which equals 9.
2. 5-√16 can be solved by simplifying √16 which is 4. So then it would become 5-4 which equals 1.
So the values of x are 9 and 1.
Answer:
Step-by-step explanation:
Hooke's Law applies here, which is a linear relationship. It would be easier to solve this using proportions with N of force on the top and the amount of stretch in cm on the bottom. Set up with our unknown, the number of cm:
and cross multiply:
20x = 300 so
x = 15 cm
There are no equations? Well there’s no picture
Answer:
101 2/3
Step-by-step explanation:
Answer:
r = 2
Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)
(-1, -5)
(r, -9)
-5 - (-9) / -1 - r = 2
4 / -1 - r = 2
r = -2
-1 - (-3) = 2
4 / 2 = 2
