Q. y=(x5)2+1y=(x-5)^{2}+1\newline(y5)/3=15(y-5)/3=15\newlineIf \newline(x,y)(x,y) is a solution to the system of equations shown and \newlinex>0x > 0, what is the value of \newlinexx ?
  1. Given Equations: We are given two equations:\newline11. y=(x5)2+1y = (x - 5)^2 + 1\newline22. y53=15\frac{y - 5}{3} = 15\newlineWe need to find the value of xx when x > 0.\newlineFirst, let's solve the second equation for yy.
  2. Solving Second Equation: Multiply both sides of the second equation by 33 to isolate yy.
    (y5)=15×3(y - 5) = 15 \times 3
    y5=45y - 5 = 45
    Now, add 55 to both sides to solve for yy.
    y=45+5y = 45 + 5
    y=50y = 50
    We have found the value of yy.
  3. Substitute and Solve: Now that we have the value of yy, we can substitute it into the first equation to solve for xx. Substitute y=50y = 50 into the first equation: 50=(x5)2+150 = (x - 5)^2 + 1
  4. Isolate Squared Term: Subtract 11 from both sides to isolate the squared term.\newline501=(x5)250 - 1 = (x - 5)^2\newline49=(x5)249 = (x - 5)^2\newlineNow we need to find the square root of both sides to solve for xx.
  5. Find Positive Solution: Taking the square root of both sides gives us two possible solutions for x5x - 5:x5=49x - 5 = \sqrt{49} or x5=49x - 5 = -\sqrt{49}x5=7x - 5 = 7 or x5=7x - 5 = -7Since we are looking for the value of xx where x > 0, we will only consider the positive solution.
  6. Final Solution: Add 55 to both sides of the equation to solve for xx: \newlinex=7+5x = 7 + 5\newlinex=12x = 12\newlineWe have found the value of xx that satisfies the system of equations and the condition x > 0.
