Methods to solve systems of equations typically find the values of variables that satisfy all equations in the system, relating this to setting equations equal to each other. Common methods include substitution, elimination, and graphing for linear equations, and factoring, using the quadratic formula, or completing the square for quadratic functions.
Methods for solving systems of equations often result in finding the values of variables that satisfy all equations in the system simultaneously. This is directly related to setting the equations equal to each other because when we equate two or more equations, we are essentially looking for their common solutions or intersection points. For instance, consider two equations y = b + mx and y = ax^2 + bx + c, linear and quadratic respectively. In order to ascertain their intersection points or common solutions, you would have to set them equal to each other, thus leading to a new equation, ax^2 + bx + c = b + mx.
The process of solving systems of equations underlies various natural phenomena and engineering processes; knowing the methods to handle these equations is crucial. For linear equations, common methods include substitution, elimination, and graphing. For quadratic functions, solutions can often be found using factoring, using the quadratic formula, or, if necessary, completing the square.
In the context of real-world applications, understanding how systems of equations function can play a part in everything from kinematic problem-solving to interpreting rates of change in scientific or technological processes. Such knowledge, then, is indispensable to anyone seeking to manage these processes effectively.

Side lengths: RS=7 and ST=7, and angle=90 degrees
Why?
Since second coordinates of R and S are the same so we can just count the length by adding first coordinate of R and first coordinate of S= |-3|+4=7
Since first coordinates of R is the same as first coordinate of T so we can just count the length by adding second coordinates of S and T=5+|-2|=7
Angle: RST is =90 degrees because triangle RST is right angled triangle. Why? Because RS is parallel to X axis(the same second coordinates of R and S) and ST is parallel to Y axis(the same coordinates of S and T) .

Answer:
What's the question? All you posted was the potential answers.
Step-by-step explanation:
By isolating the square root, squaring both sides to remove the square root, and then solving for x, the solution to the equation √(x + 3) + 4 = 5 is found to be x = -2.
To solve this equation, we start by isolating the square root. The equation given is √(x + 3) + 4 = 5. The first step is to subtract 4 from both sides of the equation to isolate the square root, resulting in √(x + 3) = 1.
Once the square root is isolated, we can square both sides of the equation to eliminate the square root, leading to x + 3 = 1² = 1.
Finally, subtract 3 from both sides, leaving us with the solution x = 1 - 3 = -2.
