Q. Solve the system of equations.y=−14x+75y=x2−14x−46Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: We have the system of equations:y=−14x+75y=x2−14x−46Set the two equations equal to each other to find the x-values where their y-values are the same.−14x+75=x2−14x−46
Simplify Quadratic Equation: Simplify the equation by moving all terms to one side to form a quadratic equation.0=x2−14x−46+14x−750=x2−121
Solve Quadratic Equation: Solve the quadratic equation. x2=121Take the square root of both sides.x=±11
Substitute for Y-Values: Find the corresponding y-values for each x-value by substituting back into one of the original equations. Let's use y=−14x+75. For x=11: y=−14(11)+75y=−154+75y=−79
Find Y-Value: Find the y-value for the second x-value.For x=−11:y=−14(−11)+75y=154+75y=229
Write Coordinates: Write the coordinates in exact form.The solutions to the system of equations are the points where the two graphs intersect.First Coordinate: (11,−79)Second Coordinate: (−11,229)
