Solve the system of equations. y = -22x + 50 y = x^2 - 22x - 50 Write the coordinates in exact form. Simplify all fractions and radicals. (______,______) (______,______)

Set Equations Equal: We have the system of equations: y = -22x + 50 y = x^2 - 22x - 50 Set the two equations equal to each other to find the x-values where they intersect. -22x + 50 = x^2 - 22x - 50Simplify Quadratic Equation: Simplify the equation by moving all terms to one side to form a quadratic equation. 0 = x^2 - 22x - 50 + 22x - 50 0 = x^2 - 100Solve for x: Solve the quadratic equation for x. x^2 = 100 Take the square root of both sides. x = ±sqrt(100) x = ±10Find y-values: Find the corresponding y-values for each x-value by substituting back into one of the original equations. Let's use y = -22x + 50. For x = 10: y = -22(10) + 50 y = -220 + 50 y = -170Find Second y-value: Find the y-value for the second x-value. For x = -10: y = -22(-10) + 50 y = 220 + 50 y = 270Write Coordinates: Write the coordinates in exact form. First Coordinate: (10, -170) Second Coordinate: (-10, 270)

Set Equations Equal: We have the system of equations: $\newline$ $y = -22x + 50$ $\newline$ $y = x^2 - 22x - 50$ $\newline$ Set the two equations equal to each other to find the $x$ -values where they intersect. $\newline$ $-22x + 50 = x^2 - 22x - 50$
Simplify Quadratic Equation: Simplify the equation by moving all terms to one side to form a quadratic equation. $\newline$ $0 = x^2 - 22x - 50 + 22x - 50$ $\newline$ $0 = x^2 - 100$
Solve for x: Solve the quadratic equation for x. $\newline$ $x^2 = 100$ $\newline$ Take the square root of both sides. $\newline$ $x = \pm\sqrt{100}$ $\newline$ $x = \pm10$
Find y-values: Find the corresponding y-values for each $x$ -value by substituting back into one of the original equations. Let's use $y = -22x + 50$ . $\newline$ For $x = 10$ : $\newline$ $y = -22(10) + 50$ $\newline$ $y = -220 + 50$ $\newline$ $y = -170$
Find Second y-value: Find the y-value for the second x-value. $\newline$ For $x = -10$ : $\newline$ $y = -22(-10) + 50$ $\newline$ $y = 220 + 50$ $\newline$ $y = 270$
Write Coordinates: Write the coordinates in exact form. $\newline$ First Coordinate: $(10, -170)$ $\newline$ Second Coordinate: $(-10, 270)$
