Q. Solve the system of equations.y=−36x+26y=x2−46x−13Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: We have the system of equations:y=−36x+26y=x2−46x−13To find the intersection points, set the two equations equal to each other.−36x+26=x2−46x−13
Rearrange and Identify Quadratic: Rearrange the equation to set it to zero and identify the quadratic equation. x2−46x−13+36x−26=0x2−10x−39=0
Factor Quadratic Equation: Factor the quadratic equation.We need to find two numbers that multiply to −39 and add up to −10. These numbers are −13 and +3.x2−13x+3x−39=0(x−13)(x+3)=0
Solve for x: Solve for x.Set each factor equal to zero and solve for x.(x−13)=0 or (x+3)=0x=13 or x=−3
Find Corresponding y-Values: Find the corresponding y-values for each x-value by substituting back into one of the original equations.For x=13:y=−36(13)+26y=−468+26y=−442For x=−3:y=−36(−3)+26y=108+26y=134
Write Coordinates: Write the coordinates in exact form.The intersection points are:First Coordinate: (13,−442)Second Coordinate: (−3,134)
