Answer:
the solution is (-4, 2)
Step-by-step explanation:
6x + 8y = -8
x + 4y = 4
... can be solved using elimination by addition and subtraction, among other methods. Multiply the second equation by -2 to obtain
6x + 8y = -8
-2x - 8y = -8
Combining these results in
4x = -16. Thus, x = -4.
Substituting -4 for x in x + 4y = 4 results in
-4 + 4y = 4, or 4y = 8, or y = 2
Then the solution is (-4, 2)
Answer:

Answer:
The property used in the simplification is: Distributive Property.
Step-by-step explanation:
" The distributive property is used to combine the two terms that had the same variable. The distributive property is the key to combining expressions with like terms.
Terms are like terms when they have the exact same variables with the exact same exponents" .
Hence, the property used in the simplification of this expression is a distributive property.
Answer:
Step-by-step explanation:
Pythagorean Theorem : In a right triangle, square of hypotenuse is equal to the sum of the squares of the other sides.
Hence these sides represent a right triangle.
Hence this does not represent a right triangle.
This represents a right triangle.
