Step-by-step explanation:
Answer:
x = 10, y = 5
Step-by-step explanation:
Substitute the second equation into the x value of the first equation.
-4x + 11y = 15
-4(2y) + 11y = 15
-8y + 11y = 15
3y = 15
y = 5
Now substitute the y value into an original equation.
x = 2y
x = 2(5)
x = 10
The correct answer to the question presented above would be letter A. -976, 563. I got this through solving with the first number of the set, then getting the ratio of the data set (which is -5) and the number of terms in the set. Thus, I arrived with the answer, -976, 563.
Answer:
Algebra is a language of symbols and operations to study the general properties of numbers. It is essential for solving many problems involving rates, costs, length, and weight. It is commonly considered to be one of the most important branches of mathematics and it has been extensively used in both pure and applied sciences.
