Q. Solve the system of equations.y=x2+24x−50y=24x+50Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: Set the two equations equal to each other since they both equal y.y=x2+24x−50y=24x+50So, x2+24x−50=24x+50.
Subtract to Zero: Subtract 24x+50 from both sides to set the equation to zero.x2+24x−50−24x−50=0This simplifies to x2−100=0.
Factor Quadratic Equation: Factor the quadratic equation. (x−10)(x+10)=0
Solve for x: Solve for x by setting each factor equal to zero.x−10=0 or x+10=0This gives us x=10 or x=−10.
Substitute x=10: Substitute x=10 into one of the original equations to find the corresponding y value.Using y=24x+50, we get y=24(10)+50.y=240+50y=290So one intersection point is (10,290).
Substitute x=−10: Substitute x=−10 into one of the original equations to find the corresponding y value.Using y=24x+50, we get y=24(−10)+50.y=−240+50y=−190So the other intersection point is (−10,−190).
