which expression is equivalent to?
262893
Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them. Example 1: Are the two expressions 2y+5y−5+8 and 7y+3 equivalent?

Answer and Explanation: Expressions that have the same value are called equivalent expressions. Equivalent numbers and expressions show up all the time in mathematics.

An equation is two expressions that are equal to each other. Short Answer: an expression can include numbers, variables, operators, sets, matrices, and other single things that can all be evaluated to one thing. An equation is two expressions that are equal to each other.

Expression has about the same meaning as phrase, except it is usually used of a phrase which is in common use. So an idiom is a certain sort of expression, which in turn is a subset of phrase: idiom > expression > phrase. An idiom can be a single word, if it's used in a way that isn't its literal or dictionary meaning.

An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.

Algebraic Expressions: is more of a phrase. It uses variables, constants, and operating symbols such as plus and multiplication. Since it is only a phrase it does not have an equal sign. For example: 5x - 2y + 3yz + 10.

The fact that 1 is less than 2 is expressed as 1 < 2, which is the same as 2 > 1, i.e., that 2 is greater than 1. The pointed end with a single endpoint points to the smaller of the two expressions. Like the symbol of equality, the symbols of comparison, may be used to make a statement or to pose a problem.

An expression is in simplest form when no terms can be combined. To express 3 + (2 × 5) in simplest form: First: perform the operation within parantheses.

algebraic expression. • a mathematical phrase combining numbers and/or variables. • an expression does not contain equality or inequality signs. but may include other operators and grouping symbols.

A term is a number or letter on its own, or numbers and letters multiplied together, such as , or 5 a 2 . An expression is a set of terms combined using the operations +, – , x or , for example 4 x − 3 or. x 2 – x y + 17 . An equation states that two expressions are equal in value, for example. 4 b − 2 = 6 .

Yes, they are the same. You just have to factor the (x2 - 1) in the numerator of f(x) and cancel out the (x + 1).

Two equations are said to be equivalent when they have the same solution set. For example, x + 2 = 6 and 2x = 8 are equivalent equations, because when we solve each of them as follows, they have the same solution set.

Similarly, when we describe an expression in words that includes a variable, we're describing an algebraic expression, an expression with a variable. For example, "three more than x" can be written as the algebraic expression. x + 3 x+ 3 x+3 .

An expression is just a mathematical phrase. ... A numerical expression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables.

Therefore two type expressions are name equivalent if and only if they are identical, that is if they can be represented by the same syntax tree, with the same labels. Structural equivalence. Replace the named types by their definitions and recursively check the substituted trees.

In programming, an expression is any legal combination of symbols that represents a value. Each programming language and application has its own rules for what is legal and illegal. For example, in the C language x+5 is an expression, as is the character string "MONKEYS."
