So in 1 hour they will be 48+55=103 miles apart
how many hours will it be in 618
103 times x hours=618
divide both sides by 103
x=618/103
x=6
the answer is 6 hours
To know if it's even based on it's prime factorization, check to see if it is a multiple of 2. If it is, it is an even number. If it is not, it is an odd number.
Answer:
Ex = - 4 + 14xy
Ey = 7x² - 7z²
Ez = -14yz
Step-by-step explanation:
The relationship between Electric field Er(x, y, z) and Electric potential, V, is a differential relationship:
Er(x, y, z) = -dV/dr(x, y, z)
Where r(x, y, z) = distance in x, y and z components.
The x component of the electric field is:
Ex = -dV/dx
Given that:
V = 4x - 7x²y + 7yz²
Ex = -dV/dx
Ex = -(4 - 14xy)
Ex = -4 + 14xy
The y component of the electric field is:
Ey = -dV/dy
Ey = -(-7x² + 7yz²)
Ey = 7x² - 7z²
The z component of the electric field is:
Ez = -dV/dz
Ez = -(14yz)
Ez = -14yz
The answer is 65 so u just leave the house and u go and get drink and hang out with your friends.
Answer:
x = -2
x = -9
Step-by-step explanation:
The linear system is:
8x - 4y = 20 ⇒ (1)
5x - 8y = 62 ⇒ (2)
To solve the system multiply equation (1) by -2 to make the coefficients of y equal in values and different in signs, then add the resulting equation with equation (2)
∵ -2(8x) + -2(-4y) = -2(20)
∴ -16x + 8y = -40 ⇒ (3)
- Add equation (2) and (3)
∴ -11x = 22
- Divide both sides by -11
∴ x = -2
Substitute the value of x in equation (1) or (2)
∵ 8(-2) - 4y = 20
∴ -16 - 4y = 20
- Add 16 to both sides
∴ - 4y = 36
- Divide both sides by -4
∴ y = -9
