Q. Solve the system of equations.y=−23x−26y=x2−36x+4Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: Set the two equations equal to each other since they both equal y. This gives us −23x−26=x2−36x+4.
Rearrange and Solve: Rearrange the equation to set it to zero and solve for x. This means we will add 23x to both sides and add 26 to both sides, resulting in x2−36x+23x+4+26=0, which simplifies to x2−13x+30=0.
Factor Quadratic Equation: Factor the quadratic equationx2−13x+30=0. The factors of 30 that add up to −13 are −10 and −3, so the factored form is (x−10)(x−3)=0.
Solve for x: Solve for x by setting each factor equal to zero. This gives us x−10=0 or x−3=0, which means x=10 or x=3.
Substitute x Values: Substitute x=10 into one of the original equations to find the corresponding y value. Using y=−23x−26, we get y=−23(10)−26, which simplifies to y=−230−26, resulting in y=−256.
Find Corresponding y Values: Substitute x=3 into one of the original equations to find the corresponding y value. Using y=−23x−26, we get y=−23(3)−26, which simplifies to y=−69−26, resulting in y=−95.
