Given the following system of linear equations, do the three tasks below. Part A: Solve the linear system of equations by graphing.
Part B: Use substitution to solve the linear system of equations.
Part C: Use addition to solve the linear system of equations.
In your final answer, include all of your work, the graph of the equations and the solution.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

b. b < 1 might be the correct answer

c.

step-by-step explanation: it's not a. because 1/3 x 1/3 x 1/3 = 1/27 so that's not correct. | b. is also not correct because 7 x 7 1/3 is not actually 3 x 7 1/3 . and for d. multiplications are not additions so that left you with c. ( hope this out : d )
