Answer: x>-4
Step-by-step explanation:
x+y=17000 (x.7+y.15)/100=2000 (7x+7y)+8y=200000. 8y=200000-17000.7 y=61.5.5.5 17000-y=9375=x x=9375

Answer: v = u= ![2 \sqrt{2}](https://tex.z-dn.net/?f=2%20%5Csqrt%7B2%7D)
Step-by-step explanation:
v= cos45 * 4= ![2 \sqrt{2}](https://tex.z-dn.net/?f=2%20%5Csqrt%7B2%7D)
- Apply Pythagorean theorem
= ![(2\sqrt{2}) ^{2} + u^{2}](https://tex.z-dn.net/?f=%282%5Csqrt%7B2%7D%29%20%5E%7B2%7D%20%2B%20u%5E%7B2%7D)
We have u = ![2 \sqrt{2}](https://tex.z-dn.net/?f=2%20%5Csqrt%7B2%7D)
