Answer:
A
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + x² = (2
)² , that is
2x² = 8 ( divide both sides by 2 )
x² = 4 ( take the square root of both sides )
x =
= 2
Answer:
x = 1 y= 3
Step-by-step explanation:
Multiply each equation by the value that makes the coefficients of y opposite.
Simplify.
Add the two equations together to eliminate y from the system.
Divide each term by 8 and simplify.
Substitute the value found for x into one of the original equations, then solve for y.
The result can be shown in multiple forms.
Point Form:
(1,3)
Equation Form:
x=1 ,y=3
