Q. Solve the system of equations.y=x2+44x+4y=44x+40Write 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.x2+44x+4=44x+40
Subtract and Simplify: Subtract 44x+4 from both sides to set the equation to zero.x2+44x+4−44x−40=0
Solve for x2: Simplify the equation.x2−36=0
Find x: Add 36 to both sides to solve for x2.x2=36
Calculate y for x=6: Take the square root of both sides to find x.x=±6
Calculate y for x=−6: Plug x back into one of the original equations to find y. Let's use y=44x+40.First, for x=6: y=44(6)+40
Write Coordinates: Calculate y for x=6.y=264+40y=304
Write Coordinates: Calculate y for x=6.y=264+40y=304Now, for x=−6: y=44(−6)+40
Write Coordinates: Calculate y for x=6. y=264+40 y=304Now, for x=−6: y=44(−6)+40Calculate y for x=−6. y=−264+40 y=−224
Write Coordinates: Calculate y for x=6.y=264+40y=304Now, for x=−6: y=44(−6)+40Calculate y for x=−6.y=−264+40y=−224Write the coordinates in exact form.First Coordinate: x=60Second Coordinate: x=61
