Q. Solve the system of equations.y=3x−44y=x2−15x−12Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Substitute y Equation: Substitute y from the first equation into the second equation: y=x2−15x−12 becomes 3x−44=x2−15x−12.
Rearrange to Set to 0: Rearrange the equation to set it to 0: x2−15x−12−3x+44=0, which simplifies to x2−18x+32=0.
Factor Quadratic Equation: Factor the quadratic equation: (x−16)(x−2)=0.
Solve for x: Solve for x: x=16 or x=2.
Substitute x=16: Substitute x=16 into the first equation to find y: y=3(16)−44, y=48−44, y=4.
Substitute x=2: Substitute x=2 into the first equation to find y: y=3(2)−44, y=6−44, y=−38.
