Q. Solve the system of equations.y=x2−22x+9y=−x−29Write 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=x2−22x+9y=−x−29So, x2−22x+9=−x−29
Move and Simplify: Move all terms to one side to set the equation to zero and simplify.x2−22x+x+9+29=0x2−21x+38=0
Factor Quadratic Equation: Factor the quadratic equation.(x−19)(x−2)=0
Solve for x: Solve for x by setting each factor equal to zero.x−19=0 or x−2=0So, x=19 or x=2
Substitute x=19: Substitute x=19 into one of the original equations to find the corresponding y value.Using y=−x−29:y=−(19)−29y=−19−29y=−48
Substitute x=2: Substitute x=2 into one of the original equations to find the corresponding y value.Using y=−x−29:y=−(2)−29y=−2−29y=−31
