Solve the system of equations.y=x2+17x−1y=−7x−24Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Q. Solve the system of equations.y=x2+17x−1y=−7x−24Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: Set the two equations equal to each other to find the x-values where the graphs intersect.y=x2+17x−1y=−7x−24x2+17x−1=−7x−24
Move and Form Quadratic Equation: Move all terms to one side to form a quadratic equation.x2+17x−1+7x+24=0x2+24x+23=0
Factor Quadratic Equation: Factor the quadratic equation.x2+24x+23=0The factors of 23 that add up to 24 are 1 and 23.(x+1)(x+23)=0
Solve for x: Solve for x by setting each factor equal to zero.(x+1)=0 or (x+23)=0x=−1 or x=−23
Substitute and Find y: Substitute the x-values back into one of the original equations to find the corresponding y-values.For x=−1:y=−7(−1)−24y=7−24y=−17For x=−23:y=−7(−23)−24y=161−24x0
Write Coordinates: Write the coordinates in exact form.The coordinates of the intersection points are (−1,−17) and (−23,137).
