Step-by-step Solution
To find the solutions to the equation \( y = \sqrt{10 - x} \), we need to solve for \( x \) in terms of \( y \). However, since the equation involves a square root, we will have to consider two cases: one where the square root is non-negative, and one where it is negative. The square root of a negative number is not a real number, so we will only consider the non-negative case.
Here are the steps to solve for \( x \):
1. Square both sides of the equation to eliminate the square root:
\[ y^2 = (\sqrt{10 - x})^2 \]
\[ y^2 = 10 - x \]
2. Rearrange the equation to solve for \( x \):
\[ x = 10 - y^2 \]
Now, we can find the ordered pairs by substituting different values of \( y \) into the equation \( x = 10 - y^2 \). Since we are looking for exact values, we will use integers or radicals for \( y \).
Solution 1:
Let's choose \( y = 0 \):
\[ x = 10 - 0^2 \]
\[ x = 10 \]
So, the first ordered pair is \( (10, 0) \).
Solution 2:
Let's choose \( y = 3 \) (since \( 3^2 = 9 \) is a perfect square and will give us a real value for \( x \)):
\[ x = 10 - 3^2 \]
\[ x = 10 - 9 \]
\[ x = 1 \]
So, the second ordered pair is \( (1, 3) \).
Therefore, the two solutions to the equation \( y = \sqrt{10 - x} \) as ordered pairs with exact values are \( (10, 0) \) and \( (1, 3) \).
Quick Answer
The two solutions are \( (10, 0) \) and \( (1, 3) \).
