Answer:
the value of x is -12 and the value of y is -4
Step-by-step explanation:
Given;
x = 3y ----- (1)
----(2)
Substitute the value of x into equation (2)
![\frac{3y}{2} + 2y = -14\\\\multiply \ through \ by \ 2\\\\3y + 4y = -28\\\\7y = -28\\\\divide \ through \ by \ 7 \\\\y = -4\\\\solve \ for \ x\\\\x = 3y\\\\x = 3(-4)\\\\x = -12](https://tex.z-dn.net/?f=%5Cfrac%7B3y%7D%7B2%7D%20%2B%202y%20%3D%20-14%5C%5C%5C%5Cmultiply%20%5C%20through%20%5C%20by%20%5C%202%5C%5C%5C%5C3y%20%2B%204y%20%3D%20-28%5C%5C%5C%5C7y%20%3D%20-28%5C%5C%5C%5Cdivide%20%5C%20through%20%5C%20by%20%5C%207%20%5C%5C%5C%5Cy%20%3D%20-4%5C%5C%5C%5Csolve%20%5C%20for%20%5C%20x%5C%5C%5C%5Cx%20%3D%203y%5C%5C%5C%5Cx%20%3D%203%28-4%29%5C%5C%5C%5Cx%20%3D%20-12)
Thus, the value of x is -12 and the value of y is -4
Answer:
High velocity train will take 36.73 hours to travel from Paris and Naples.
Explanation:
Average speed = Distance traveled / Time taken
Time taken = Distance traveled / Average speed.
Distance traveled = 7346 km
Average speed = 200 km/hr.
Time taken = 7346 / 200 = 36.73 hour.
So, high velocity train will take 36.73 hours to travel from Paris and Naples.
Answer:
9
Step-by-step explanation:
Value of 'a' = 15
Value of 'b' = 6
Simplifying the expression given in question,
![9a^{2} -48ab+64b^{2}](https://tex.z-dn.net/?f=9a%5E%7B2%7D%20-48ab%2B64b%5E%7B2%7D)
![=> (3a)^{2} - 2*3a*8b+(8b)^{2}](https://tex.z-dn.net/?f=%3D%3E%20%283a%29%5E%7B2%7D%20-%202%2A3a%2A8b%2B%288b%29%5E%7B2%7D)
![=>(3a-8b)^{2}](https://tex.z-dn.net/?f=%3D%3E%283a-8b%29%5E%7B2%7D)
Putting 'a' & 'b' in above expression ,
![(3a-8b)^{2} = (3*15-8*6)^{2} = (45-48)^{2} = (-3)^{2} =9](https://tex.z-dn.net/?f=%283a-8b%29%5E%7B2%7D%20%3D%20%283%2A15-8%2A6%29%5E%7B2%7D%20%3D%20%2845-48%29%5E%7B2%7D%20%20%3D%20%28-3%29%5E%7B2%7D%20%3D9)
