For this case we must resolve the following inequality:
Subtracting 8 from both sides of the inequality:
Equal signs are added and the same sign is placed.
Thus, the solution is given by all values of "y" greater than or equal to -20.
Answer:
"y" belongs to the set [-20,∞)
Answer:
x = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of squares on the other 2 sides, that is
x² + 12² = 13²
x² + 144 = 169 ( subtract 144 from both sides )
x² = 25 ( take the square root of both sides )
x = = 5
