6The line of best fit has the equation = -3 + 2.5x. What does this equation predict for a value of x = 3?Answer: 4.5
x = sqrt 100
It is an incorrect equation.
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
An exact differential equation is a type of first-order differential equation that can be expressed in the form ( M(x, y) , dx + N(x, y) , dy = 0 ), where ( M ) and ( N ) are continuously differentiable functions. An equation is considered exact if the partial derivative of ( M ) with respect to ( y ) equals the partial derivative of ( N ) with respect to ( x ), i.e., ( \frac{\partial M}{\partial y} = \frac{\partial N}{\partial x} ). This condition indicates that there exists a function ( \psi(x, y) ) such that ( d\psi = M , dx + N , dy ). Solving an exact differential equation involves finding this function ( \psi ).
dy/dx = 2cos2x
dy/dx = m
Because homogeneous equations normally refer to differential equations. The one in the question is not a differential equation.
Exact differentials refer to changes in a function that can be expressed as the total differential of that function, meaning there exists a scalar function whose differential equals the given expression. Inexact differentials, on the other hand, cannot be derived from a single function and typically arise in contexts like thermodynamics, where they represent changes in quantities that are path-dependent. In mathematical terms, an exact differential ( df ) satisfies the condition ( \frac{\partial^2 f}{\partial y \partial x} = \frac{\partial^2 f}{\partial x \partial y} ), while inexact differentials, such as ( dQ ) or ( dW ), do not meet this criterion.

The differential equation of the family of straight lines y = mx is given by dy/dx = m. This equation represents that the slope of the line at any point is equal to the constant m. Different values of m will yield different lines within the family.
