Q. Solve the system of equations.y=−26x+48y=x2−26x−33Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Substitute y Equation: Substitute y from the first equation into the second equation: y=x2−26x−33 becomes −26x+48=x2−26x−33.
Simplify Equation: Simplify the equation by adding 26x to both sides and subtracting 48 from both sides: 0=x2−81.
Factor Quadratic Equation: Factor the quadratic equation: 0=(x−9)(x+9).
Solve for x: Solve for x by setting each factor equal to zero: x−9=0 or x+9=0.
Find x-values: Find the two x-values: x=9 or x=−9.
Substitute x=9: Substitute x=9 into the first equation to find the corresponding y-value: y=−26(9)+48.
Calculate y for x=9: Calculate the y-value for x=9: y=−234+48.
Simplify y for x=9: Simplify to find the y-value: y=−186.
Substitute x=−9: Substitute x=−9 into the first equation to find the corresponding y-value: y=−26(−9)+48.
Calculate y for x=−9: Calculate the y-value for x=−9: y=234+48.
Simplify y for x=−9: Simplify to find the y-value: y=282.
Write Coordinate Points: Write the solution as coordinate points: (9,−186) and (−9,282).
