Q. Solve the system of equations.y=−27x+49y=x2−15x+4Write 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+4 becomes −27x+49=x2−15x+4.
Rearrange to Set to 0: Rearrange the equation to set it to 0: x2−15x+4+27x−49=0, which simplifies to x2+12x−45=0.
Factor Quadratic Equation: Factor the quadratic equation: (x+15)(x−3)=0.
Solve for x: Solve for x: x+15=0 or x−3=0, so x=−15 or x=3.
Calculate y for −15: Substitute x=−15 into the first equation to find y: y=−27(−15)+49.
Calculate y for 3: Calculate y for x=−15: y=405+49, which is y=454.
Substitute x to Find y: Substitute x=3 into the first equation to find y: y=−27(3)+49.
Calculate y for 3: Calculate y for x=3: y=−81+49, which is y=−32.
Write Solution as Points: Write the solution as coordinate points: The coordinate points are (−15,454) and (3,−32).
