Q. Solve the system of equations.y=13x−44y=x2+33x−8Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: Since both equations are equal to y, we can set them equal to each other to find x. This gives us the equation 13x−44=x2+33x−8.
Rearrange and Solve: Rearrange the equation to set it to zero and solve for x. This means subtracting 13x and adding 44 to both sides, resulting in 0=x2+20x−36.
Factor Quadratic Equation: Factor the quadratic equationx2+20x−36. The factors of −36 that add up to 20 are 26 and −6. This gives us (x+26)(x−6)=0.
Solve for x: Set each factor equal to zero and solve for x. This gives us two solutions: x+26=0, which means x=−26, and x−6=0, which means x=6.
Substitute x=−26: Substitute x=−26 into one of the original equations to find the corresponding y value. Using y=13x−44, we get y=13(−26)−44, which simplifies to y=−338−44, resulting in y=−382.
Substitute x=6: Substitute x=6 into one of the original equations to find the corresponding y value. Using y=13x−44, we get y=13(6)−44, which simplifies to y=78−44, resulting in y=34.
