Answer:

The answer to your question is two atoms of Magnesium

Step-by-step explanation:

Data

Molecule = MgSO₄

2 molecules of MgSO₄ has

Process

From the options given we know that we must know the number of each element in the molecules of magnesium sulfate.

To determine this number, multiply the coefficient 2 by the subscripts of each element.

                        2MgSO₄ = Mg₂ S₂ O₈

Conclusion

2 molecules of MgSO₂ have = 2 atoms of Magnesium

                                                   2 atoms of Sulfur

                                                   8 atoms of Oxygen

Okay so the circle on the line plot, if it is empty In the middle it is > or < if it is solid it is ≤ ≥. In this case it not solid so it will be > or < . The plot is at -1 1/2 and is going positive. So it would be a > -1 1/2

A. The solution is (−2,−3)
Cerrena [4.2K]

Answer:

  D.  (-3, -2)

Step-by-step explanation:

The equations have different coefficients for x and y, so will have one solution. The solutions offered are easily tested in either equation.

Using (x, y) = (-2, -3):

  x = y -1  ⇒  -2 = -3 -1 . . . . False

Using (x, y) = (-3, -2):

  x = y -1  ⇒  -3 = -2 -1 . . . .True

  2x = 3y  ⇒  2(-3) = 3(-2) . . . . True

The solution is (-3, -2).

__

If you'd like to solve the set of equations, substitution for x works nicely.

  2(y -1) = 3y

  2y -2 = 3y . . eliminate parentheses

  -2 = y . . . . . . subtract 2y

  x = -2 -1 = -3

The solution is (x, y) = (-3, -2).
