Q. Solve the system of equations.y=50x−33y=x2+32x−1Write 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 50x−33=x2+32x−1.
Rearrange and Solve: Rearrange the equation to set it to zero and solve for x. This means we subtract 50x−33 from both sides to get 0=x2+32x−50x−1+33, which simplifies to 0=x2−18x+32.
Factor Quadratic Equation: Factor the quadratic equationx2−18x+32=0. The factors of 32 that add up to −18 are −16 and −2. So the factored form is (x−16)(x−2)=0.
Solve for x: Solve for x by setting each factor equal to zero. This gives us x−16=0 or x−2=0, which means x=16 or x=2.
Substitute x Values: Substitute x=16 into one of the original equations to find y. Using y=50x−33, we get y=50(16)−33, which simplifies to y=800−33, giving us y=767.
Find y Values: Substitute x=2 into the same equation to find the other value of y. Using y=50x−33, we get y=50(2)−33, which simplifies to y=100−33, giving us y=67.
Write Coordinate Points: Write the solution as coordinate points. The coordinate points are (16,767) and (2,67).
