Q. Solve the system of equations.y=x2+44x+8y=44x+44Write 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+44x+8y=44x+44So, x2+44x+8=44x+44
Subtract and Simplify: Subtract 44x+44 from both sides to set the equation to zero.x2+44x+8−(44x+44)=0This simplifies to x2−36=0
Factor Quadratic Equation: Factor the quadratic equation. x2−36=(x+6)(x−6)=0
Solve for x: Solve for x using the zero product property.x+6=0 or x−6=0This gives us x=−6 or x=6
Substitute x=−6: Substitute x=−6 into one of the original equations to find the corresponding y value.Using y=44x+44, we get y=44(−6)+44=−264+44=−220So one point of intersection is (−6,−220).
Substitute x=6: Substitute x=6 into one of the original equations to find the corresponding y value.Using y=44x+44, we get y=44(6)+44=264+44=308So the other point of intersection is (6,308).
