Q. Solve the system of equations.y=−14x−31y=x2−27x+9Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Move and Simplify: Now, let's move everything to one side to get a quadratic equation.x2−27x+14x+9+31=0x2−13x+40=0
Factor Quadratic Equation: Next, we need to factor the quadratic equation. (x−5)(x−8)=0
Solve for x: Now, we solve for x by setting each factor equal to zero.x−5=0 or x−8=0So, x=5 or x=8
Find y-values: Let's find the corresponding y-values by plugging x back into one of the original equations.For x=5, y=−14(5)−31 which gives us y=−70−31 so y=−101.
Find y-values: Now, for x=8, y=−14(8)−31 which gives us y=−112−31 so y=−143.
Write Coordinates: Finally, we write the coordinates in exact form. The first coordinate is (5,−101) and the second coordinate is (8,−143).
