Q. Solve the system of equations.y=−17x+16y=x2−18x−26Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: First, let's set the two equations equal to each other since they both equal y.−17x+16=x2−18x−26
Move to One Side: Now, let's move everything to one side to set the equation to zero.x2−18x+17x−26−16=0x2−x−42=0
Factor Quadratic Equation: Next, we need to factor the quadratic equation. Looking for two numbers that multiply to −42 and add up to −1, we get −7 and 6. So, (x−7)(x+6)=0
Solve for x: Now, solve for x by setting each factor equal to zero.x−7=0 or x+6=0 So, x=7 or x=−6
Find Corresponding y Values: We have two values for x, let's find the corresponding y values.Substitute x=7 into y=−17x+16 to get y=−17(7)+16=−119+16=−103.Substitute x=−6 into y=−17x+16 to get y=−17(−6)+16=102+16=118.
Write Coordinates: Finally, we write the coordinates in exact form.The first coordinate is (7,−103).The second coordinate is (−6,118).
