Q. Solve the system of equations.y=−5x+6y=x2−5x−43Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Substitute y Equation: Substitute y from the first equation into the second equation: y=x2−5x−43 becomes −5x+6=x2−5x−43.
Simplify Equation: Simplify the equation: 0=x2−5x−43+5x−6.
Combine Like Terms: Combine like terms: 0=x2−49.
Add 49: Add 49 to both sides: 49=x2.
Take Square Root: Take the square root of both sides: x=±7.
Substitute x for y: Substitute x back into the first equation to find y when x=7: y=−5(7)+6.
Calculate y: Calculate y: y=−35+6.
Simplify y: Simplify y: y=−29.
Substitute x for y: Now substitute x back into the first equation to find y when x=−7: y=−5(−7)+6.
Calculate y: Calculate y: y=35+6.
Simplify y: Simplify y: y=41.
