The mass of an object will never change no matter what, however, the weight relies on gravity. So therefore, the answer would be D.
Answer:
Option (a) is correct.
The system of equation becomes
Step-by-step explanation:
Given : Equation 
We have to construct a system of equations that can be used to find the roots of the equation
Consider the given equation
To construct a system of equation put both sides of the given equation equal to a same variable.
Let the variable be "y", Then the equation
becomes,
Thus, The system of equation becomes
Option (a) is correct.
Equation of a line passing through point (x1, y1) with slope m is given by y - y1 = m(x - x1)
For parallel lines, the slope of the required line is equal to the slope of the given line.
x = -3 is a vertical line, therefore, the required line will also be a vertical line since they are parallel.
Since the required line passes through point (4, 2), the equation of the required line is x = 4.
