Q. Solve the system of equations.y=−32x+20y=x2−37x−16Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Substitute y into second equation: Substitute y from the first equation into the second equation to find x. This gives us −32x+20=x2−37x−16.
Rearrange to set to zero: Rearrange the equation to set it to zero: x2−37x+32x−16−20=0. This simplifies to x2−5x−36=0.
Factor the quadratic equation: Factor the quadratic equation: (x−9)(x+4)=0.
Solve for x: Solve for x by setting each factor equal to zero: x−9=0 or x+4=0. This gives us x=9 or x=−4.
Substitute x=9 into first equation: Substitute x=9 into the first equation y=−32x+20 to find y. This gives us y=−32(9)+20.
Calculate y when x=9: Calculate y when x=9: y=−288+20, which simplifies to y=−268.
Substitute x=−4 into first equation: Substitute x=−4 into the first equation y=−32x+20 to find y. This gives us y=−32(−4)+20.
Calculate y when x=−4: Calculate y when x=−4: y=128+20, which simplifies to y=148.
