Q. Solve the system of equations.y=−23x+13y=x2−13x−26Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: We have the following system of equations:y=−23x+13y=x2−13x−26To find the solution, we will set the two equations equal to each other since they both equal y.−23x+13=x2−13x−26
Rearrange and Form Quadratic Equation: Rearrange the equation to bring all terms to one side and set it equal to zero to form a standard quadratic equation.x2−13x−26+23x−13=0x2+10x−39=0
Factor Quadratic Equation: Factor the quadratic equation to find the values of x. We are looking for two numbers that multiply to −39 and add up to 10. These numbers are 13 and −3. (x+13)(x−3)=0
Solve for x: Solve for x by setting each factor equal to zero.x+13=0 or x−3=0x=−13 or x=3
Find y-values: Find the corresponding y-values for each x-value by substituting back into one of the original equations. We can use y=−23x+13.For x=−13:y=−23(−13)+13y=299+13y=312
Find y-value for x=3: Find the y-value for x=3:y=−23(3)+13y=−69+13y=−56
Write Coordinates: Write the coordinates in exact form.The solutions to the system of equations are the points where the two equations intersect.First Coordinate: (−13,312)Second Coordinate: (3,−56)
