Answer:
The value of x and y for the given two linear equation is x = 7 , y = - 3
Step-by-step explanation:
Given two linear equation as :
x + 2 y - 1 = 0
Or, x + 2 y = 1 ..........A
x - 2 y = 13 ............B
Now, Solving both equations A and B
i.e (x + 2 y) + (x - 2 y) = 1 + 13
Or, (x + x) + (2 y - 2 y) = 14
Or, 2 x + 0 = 14
Or, 2 x = 14
∴ x =
i.e x = 7
Now, Put the value of x into eq A
So, 7 + 2 y = 1
Or, 2 y = 1 - 7
Or, 2 y = - 6
∴ y =
i.e y = - 3
So, The value s of x = 7 and y = - 3
Hence, The value of x and y for the given two linear equation is x = 7 , y = - 3 Answer
Answer:
1.4 times as high
Step-by-step explanation:
Now here we have to compare the both final velocities by using the formula independent of time. As we know,
2aS = V(f)2 - V(i)2
Both balls are dropped from certain height, so V(i) = 0 m/s for both balls
So, 2aS = V(f)2 for both balls.
Now if we compare both velocities
Equation for first ball
2aS(1) = V(1)2
Equation for second ball
2aS(2) = V(2)2
Comparing both equations
2aS(1)/2aS(2) = V(1)2/V(2)2
as we now S(1) = 5m and S(2) = 10m, also acceleration a = g, because acceleration due to gravity is acting on the balls. So,
2(9.8) x 5/2(9.8) x 10 = V(1)2/V(2)2
after simplifying,
1/2 = V(1)2/V(2)2
V(2)^2 = 2V(1)^2
By taking square root on both sides,
V(2) = 1.4V(1)
The GCF of 18 and 24 is 6. And the GCF of 10 and 90 is 18.
Hope this helps! :D
