Q. Solve the system of equations.\newliney=17x36y = -17x - 36\newliney=x2+x+9y = x^2 + x + 9\newline\newlineWrite the coordinates in exact form. Simplify all fractions and radicals.\newline(______,______)\newline(______,______)
  1. Substitute yy into second equation: Substitute yy from the first equation into the second equation to solve for xx. This gives us the equation 17x36=x2+x+9-17x - 36 = x^2 + x + 9.
  2. Rearrange and simplify equation: Rearrange the equation to set it to zero: x2+x+9+17x+36=0x^2 + x + 9 + 17x + 36 = 0, which simplifies to x2+18x+45=0x^2 + 18x + 45 = 0.
  3. Factor quadratic equation: Factor the quadratic equation: (x+3)(x+15)=0(x + 3)(x + 15) = 0.
  4. Solve for x: Solve for x by setting each factor equal to zero: x+3=0x + 3 = 0 or x+15=0x + 15 = 0.
  5. Find x solutions: Find the two solutions for x: x=3x = -3 or x=15x = -15.
  6. Substitute x=3x = -3 into first equation: Substitute x=3x = -3 into the first equation y=17x36y = -17x - 36 to find the corresponding yy value: y=17(3)36y = -17(-3) - 36.
  7. Calculate yy for x=3x = -3: Calculate the yy value for x=3x = -3: y=5136y = 51 - 36, which simplifies to y=15y = 15.
  8. Substitute x=15x = -15 into first equation: Substitute x=15x = -15 into the first equation y=17x36y = -17x - 36 to find the corresponding yy value: y=17(15)36y = -17(-15) - 36.
  9. Calculate yy for x=15x = -15: Calculate the yy value for x=15x = -15: y=25536y = 255 - 36, which simplifies to y=219y = 219.
  10. Write solutions as coordinate points: Write the solutions as coordinate points. The coordinate points are (3,15)(-3, 15) and (15,219)(-15, 219).
