The value for x is already given; x = -2
Substitute -2 in for x in the second equation.
y = 2/3(-2) + 3
y = -4/3 + 3
y = 5/3
The final answer is (-2, 5/3).
Answer:
x = 25
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse x is equal to the sum of the squares on the other two sides, that is
x² = 20² + 15² = 400 + 225 = 625 ( take the square root of both sides )
x =
= 25
