Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations.
2x + y + 4z = 16
5x – 2y + 2z = -1
x + 2y - 32 = -9
a. (-1,2, 22)
c. (-1, 2, 4)
b. (-10, 22, 42)
d. (-10, 2, 22)
HELP ASAP PLEASE

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

the answer to your question is c.)   volcanoes built the mountains and earthquakes tore them down.

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
