Round to the Nearest tenth

a. x=4.2, y=3

Step-by-step explanation:

We know the degrees of the two angles: Right angle (90 degrees) and 45 degrees.

The sum of the interior angles of a triangle is equal to 180 degrees, so the unknown angle is 45 degrees.

The two angles below are both 45 degrees, indicating that the side length is also 3.

So y is equal to 3, the answer can only be a.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
