With Answer And Solution

With answer and solution

 

Answer:

1) Solve for x:

1/x + 2/y = 1

Change to standard for by multiplying each term by LCF xy:

(xy) 1/x + 2/y = 1 (xy)

y + 2x = xy

2x-xy = -y

Factor the left side of equation:

x(-y+2) = -y

Solve for x:

x(-y+2) = -y

x(-y+2)/(-y+2)  =  -y/(-y+2)

x = y/(y-2)

2.) Simplify:

(b)(b³) ÷ b+b+

= (b⁴) ÷ 3

= b³/3

"The Impulse Experienced By A Body Is Equal To The Change In Its:, A. Velocity, B. Kinetic Energy, C. Momentum, D. Potential Energy, "

"The impulse experienced by a body is equal to the change in its: a. Velocity b. Kinetic energy c. Momentum d. Potential energy "   Answer: The impulse experienced by a body is equal to the change in its C. MOMENTUM Explanation: Impulse refers to the quantity or value that represents the overall effect of a force acting over time. It is usually given a unit of Newton-seconds. Now, as this force changes, the momentum also changes. This is a logical equivalent of Newton's second law of motion (Force Law), read more here:   brainly.ph/question/1559067 In Physics, Momentum is defined as the quantity of motion that an object has. Momentum also refers to a measurement of mass in motion. This value is computed by getting the product of the mass and velocity of an object. It is usually represented by the symbol p. So, by definition, the formula for momentum is   p = m · v   wherein m is mass and v is velocity. Remember that Momentum is a vector quantity that has...

What Is Big Bang Theory About?

What is big bang theory about?   Answer: The Big Bang theory is the prevailing cosmological model for the observable universe from the earliest known periods through its subsequent large-scale evolution. The model describes how the universe expanded from a very high-density and high-temperature state, and offers a comprehensive explanation for a broad range of phenomena, including the abundance of light elements, the cosmic microwave background (CMB), large scale structure and Hubbles law (the farther away galaxies are, the faster they are moving away from Earth). If the observed conditions are extrapolated backwards in time using the known laws of physics, the prediction is that just before a period of very high density there was a singularity which is typically associated with the Big Bang. Physicists are undecided whether this means the universe began from a singularity, or that current knowledge is insufficient to describe the universe at that time. Detailed measurements of th...

Would Meaningful, Wider, More Active Participation Be Limited To The Local Government Units?

Would meaningful, wider, more active participation be limited to the local government units?   Would meaningful, wider, more active participation be limited to the local government units? No, the meaningful, wider, more active participation should not be limited to the local government units. It should include the national government units as well as the participation of the citizens of the country. Both the government and the people must hold hand in hand for us to reach mutual goals.
