Q. Solve the system of equations.y=−27x+1y=x2−26x−41Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: We have the system of equations:y=−27x+1y=x2−26x−41To find the intersection points, we set the two equations equal to each other.−27x+1=x2−26x−41
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.x2−26x−41+27x−1=0x2+x−42=0
Factor Quadratic Equation: Factor the quadratic equation.We look for two numbers that multiply to −42 and add up to 1. These numbers are 7 and −6.(x+7)(x−6)=0
Solve for x: Solve for x by setting each factor equal to zero.x+7=0 or x−6=0x=−7 or x=6
Find y for x=−7: Find the corresponding y-values for each x-value by substituting back into one of the original equations. We can use y=−27x+1.For x=−7:y=−27(−7)+1y=189+1y=190
Find y for x=6: Find the corresponding y-value for x=6: y=−27(6)+1 y=−162+1 y=−161
Write Coordinates: Write the coordinates in exact form.The first coordinate is (−7,190).The second coordinate is (6,−161).
