Q. Solve the system of equations.y=x2−12x−9y=−24x−44Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: We have the system of equations:y=x2−12x−9y=−24x−44To find the intersection points, we need to set the two equations equal to each other.x2−12x−9=−24x−44
Rearrange and Solve: Now, we rearrange the equation to bring all terms to one side and set it equal to zero.x2−12x−9+24x+44=0x2+12x+35=0
Factor Quadratic Equation: Next, we factor the quadratic equation.In the form ax2+bx+c, we need two numbers that multiply to c (35) and add up to b (12). These numbers are 5 and 7.(x+5)(x+7)=0
Solve for x: Now, we solve for x by setting each factor equal to zero.(x+5)=0 or (x+7)=0 This gives us x=−5 and x=−7.
Find y Values: We have two values for x: x1=−5 and x2=−7. Now we need to find the corresponding y values by substituting x back into one of the original equations. We can use y=−24x−44. For x1=−5: y=−24(−5)−44=120−44=76 For x2=−7: y=−24(−7)−44=168−44=124
Coordinates of Intersection Points: We now have the coordinates of the intersection points in exact form.First Coordinate: (−5,76)Second Coordinate: (−7,124)
