Q. Solve the system of equations.y=x2−36x−29y=−21x−43Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: We have the following system of equations:y=x2−36x−29y=−21x−43To find the solution, we will set the two equations equal to each other since they both equal y.x2−36x−29=−21x−43
Rearrange and Form Quadratic Equation: Rearrange the equation to bring all terms to one side and set it equal to zero to form a standard quadratic equation.x2−36x−29+21x+43=0x2−15x+14=0
Factor Quadratic Equation: Factor the quadratic equation.We are looking for two numbers that multiply to 14 and add up to −15. These numbers are −1 and −14.x2−15x+14=(x−1)(x−14)
Solve for x: Solve for x by setting each factor equal to zero.(x−1)=0 or (x−14)=0This gives us two solutions for x:x=1 and x=14
Find Corresponding y-values: Find the corresponding y-values for each x-value by substituting back into either of the original equations. We'll use y=−21x−43.For x=1:y=−21(1)−43y=−21−43y=−64For x=14:y=−21(14)−43y=−294−43y=−337
Write Coordinates: Write the coordinates in exact form.The solutions to the system of equations are the points where the two graphs intersect, which are the x-values we found and their corresponding y-values.First Coordinate: (1,−64)Second Coordinate: (14,−337)
