Final answer:
The student's question is about solving 2x2 systems of equations using a calculator. Equations A, B, and C are linear as they follow the format y = mx + b. Calculators such as the TI-83 series can solve these by inputting coefficients into their matrix functions.
Step-by-step explanation:
The student's question pertains to solving 2x2 systems of equations using a calculator. From the given options, A) 2x2 Equation Solver, B) Matrix Systems Calculator, C) Two-by-Two System Solver, and D) Linear System Solver, each of these terms could be used to refer to a function or program that might assist in solving a system of linear equations.
The correct answer to which of the following equations are linear is E) A, B, and C. All three equations are linear since they are of the form y = mx + b, representing a straight line when graphed on a coordinate plane.
Solution Steps Using Calculator:
- Input the coefficients of the variables and constants into the matrix function of the TI-83, 83+, or 84 calculators.
- Use the calculator's function to solve the system of equations.
It is important to mention that when dealing with quadratic equations, characterized by the variable being squared (like x2), there will typically be two solutions.
