Question

Trevor simplifies a linear equation with the variable x and gets 6=6 as a result. Which statement is true about the linear equation?
A. The linear equation has a solution of only 0 because that simplified equation has no variable.
B. The linear equation has no solution of only 6 because that is the value remaining in the simplified equation.
C. The linear equation has infinitely many solutions because the simplified equation statement.
D. The linear equation has no solutions because the simplified equation has no variable.

Answer 1

Answer:

C

Step-by-step explanation:

Whenever our simplification of a linear equation ends in a true statement, in this case 6=6, then our linear equation has infinitely many solutions.

Therefore, our answer is C.

In general:

• If we get a true statement (e.g. x=x, 6=6, etc.), then our linear equation has infinitely many solutions.
• If we get a false statement (e.g. 0=1, 7=2, etc.), then our linear equation has no solution.
• And if we get a variable equal to a value (x=2, x=7/2, etc.), then our linear equation has exactly one solution.

This is because if we get a true statement, then this implies that the two linear equations are the exact same line.

If we get a false statement, this implies that the two lines are parallel but not the same. They will never intersect.

And if we get a variable equal to a value, this implies that the two lines are not the same but they will intersect. Since they are lines, they will only intersect once, giving us only one solution.

Answer 2

Answer:

its 109384

Step-by-step explanation:

These models show the electron structures of two different nonmetal elements.

Which element is likely more reactive, and why?

Element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table.

Element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table.

Element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons.

Element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.
