Q. Solve the system of equations.y=12x−37y=x2+2x−21Write 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. Since y=12x−37 and y=x2+2x−21, we can set them equal to each other: 12x−37=x2+2x−21.
Rearrange and solve for x: Rearrange the equation to set it to zero and solve for x: x2+2x−21−12x+37=0, which simplifies to x2−10x+16=0.
Factor the quadratic equation: Factor the quadratic equation: (x−8)(x−2)=0.
Solve for x: Solve for x by setting each factor equal to zero: x−8=0 or x−2=0. This gives us x=8 or x=2.
Substitute x=8 to find y: Substitute x=8 into the first equation to find y: y=12(8)−37, which simplifies to y=96−37, so y=59.
Substitute x=2 to find y: Substitute x=2 into the first equation to find y: y=12(2)−37, which simplifies to y=24−37, so y=−13.
