One type of energy change or transference is putting gas into your car because your converting chemical-energy into motion or kinetic-energy!
If you add it it'll become -3x^2+5x+7
Answer: The first free elections under the Sáenz Peña regime were held in 1916. Women did not have the right to vote in Argentina until 1947, when Law 13.010 ("on political rights for women") was sanctioned during the government of Juan Domingo Perón. Women first voted in a national election in 1951.
Explanation:
The answer to this is True. The government controls major aspects of economic production.
Answer:
-12
Explanation:
We are given information to solve for 2 variables x and y. To solve this I substituted 3x for y in the equation 5x - 4y = 21
So substituting gets us 5x - 4(3x) = 21
and we can solve the equation for x
5x - 12x = 21
-7x = 21
x = -3
Now that we have found x, we can find y simply by putting it in the equation y = 3x
y = 3(-3) = -9
Once we have both variables, we can find the answer to x + y
-3 + -9 = -3 - 9 = -12
So the answer to the question
x + y = -12
