We know in these kind of triangles that have a 90 degrees angle, we can do:
so the first question:
and then:
so , when you want to rationalize , usually you must multiply the irrational factor as 1:
so , now multiply:
in the next question,we know negative numbers in radical don't have any solution so 2 is correct,

Answer:
a. Yes
b. No
Step-by-step explanation:
To find if an ordered pair is a solution to the inequality, substitute its x and y values for the x and y in the inequality and solve. If the equation is true, then it is a solution. If it is not, then it is not a solution.
1) First, substitute the x and y values of (3, 1) into the inequality. So, substitute 3 for x and 1 for y:
1 is greater than or equal to 1, so (3,1) is a solution.
2) Second, do the same with the point (1, -4). Substitute 1 for x and -4 for y:
However, -4 is not greater than or equal to -3, thus (1, -4) is not a solution.
