|2| = y is valid, but the use of modulus is pointless in this equation, since |2| = +2.
The equation, therefore, is y = 2
If, instead, the equation were 2 = |y|, then you would have y = -2 or +2.
A mathematical expression has numbers and operation signs with no equal sign. Equations, on the other hand, do contain equal signs.
No, inequalities have more than, less then, at least, or no more than signs. Equations just have equal signs. An inequality answer can't be written as just a number it has to have a sign with it.
Yes, and it would be a negative slope.
Expressions do not have equal signs, but equations do. Just think: "Equations are equal!" CX expression is kind of like an expression. example (56+49). think of the x in e(x)pression as if it's marking out the equal sign as not to be used. Equation is kind of easy. Opposite of expression. example (56+49=105). think of the O in equati(O)n as if it's circling the equal sign as to be used.
An equation consists of an equal sign, and an expression on each side of it. The equal sign states that the two parts are equal. Examples: 3 = 3 4 = 5 x + 1 = 7 (The first is true, the second is false, the truth of the third one depends on the value assigned to "x"; but all three are equations.) An inequality is similar, but the equal sign is replaced by one of the following signs: less-than, less-than-or-equal, greater-than, greater-than or equal.
No they do not, equations have equal signs.
Yes
no algebraic expressions do not have equal signs but equations do.
A mathematical expression has numbers and operation signs with no equal sign. Equations, on the other hand, do contain equal signs.
Inequalities have greater than, less than, greater than or equal to, or less than or equal to signs. Equations have an equal sign.
yes. equations have an equals signs and expressions don't
No, expressions do not have equal signs. Equations do, though. You can think of it like this: Equtions have EQUAl signs, while expressions do not.No, an expression cannot have an equal sign. If it were to have an equal sign, it would then be an equation.
To solve a system of equations, you need equations (number phrases with equal signs).
No, inequalities have more than, less then, at least, or no more than signs. Equations just have equal signs. An inequality answer can't be written as just a number it has to have a sign with it.

The given expressions can't be considered to be equations because there are no equality signs.
