Does 5x mean 5 times X?
If you mean that the variable x takes on a value of 6.15, then simply replace x by 6.15 in the expression 5x and evaluate that. And, again, 5x means 5 times x.
What would 2x times X be?
The answer is 2×2.
What does 5y mean in math?
Thus, 5y means “5 times y” and 2(x + 1) means “2 times the whole expression (x + 1).” Also, from this point forward, I will usually use the symbol “” to indicate multiplication, because it’s too easy to mix up the other multiplication symbol, , with the variable x.
What is the meaning of 5x?
Acronym Definition 5X UPS Air Cargo (airline code).
How do you solve this math problem?
Here are four steps to help solve any math problems easily: Read carefully, understand, and identify the type of problem. Draw and review your problem. Develop the plan to solve it. Solve the problem.
What is x2 times x2?
Answer: x squared times x squared is x raised to the power of 4. So, x2 × x2 = x4.
How do multiply fractions?
There are 3 simple steps to multiply fractions Multiply the top numbers (the numerators). Multiply the bottom numbers (the denominators). Simplify the fraction if needed.
What is the product X 5 )( x 5?
Answer: The product of (x+5)(x-5) is x2 – 25. Explanation: We know the algebraic identity (a + b) (a – b) as a2 – b2.
What is the formula of a b )( ab?
The formula for a2– b2 is (a+b)(a-b)= a2– b2. It is called the difference of squares formula.
Is 7 a term?
The 5x is one term and the 7y is the second term. The two terms are separated by a plus sign. + 7 is a three termed expression.
What is mathematical sentence example?
A mathematical sentence is the analogue of an English sentence; it is a correct arrangement of mathematical symbols that states a complete thought. For example, the sentence ‘1+2=3 1 + 2 = 3 ‘ is true. The sentence ‘1+2=4 1 + 2 = 4 ‘ is false.
What is the slope of y =- 5 4xy?
Pre-Algebra Examples Using the slope-intercept form, the slope is −4 .
What does 10X mean?
10X means “Thanks.” It an informal way of expressing gratitude.
What does 5X mean in stocks?
A P/E of 5x means a company’s stock is trading at a multiple of five times its earnings. A P/E of 10x means a company is trading at a multiple that is equal to 10 times earnings. A company with a high P/E is considered to be overvalued.
Does 0 squared exist?
The square root of zero is zero.
What is 2 raised power 5?
Answer: 2 to the power 5 can be expressed as 25 = 2 × 2 × 2 × 2 × 2 = 32.
What is 4 as a power of 2?
Answer: 4 to the power of 2 can be expressed as 42 = 4 × 4 = 16.
How do you multiply fractions examples?
For example, let us multiply the following fractions: 2/3 × 4/5. We start by multiplying the numerators: 2 × 4 = 8, then, the denominators: 3 × 5 = 15. This can be written as: (2 × 4)/(3 × 5) = 8/15. Now, the product is already in its lowest terms, so we need not reduce it and we give this as the answer.
What is the complete factor of n² 16n 64?
The factored form of the polynomial is (n+8)2 .
What is the product of something?
In mathematics, a product is the result of multiplication, or an expression that identifies factors to be multiplied. For example, 30 is the product of 6 and 5 (the result of multiplication), and is the product of and. (indicating that the two factors should be multiplied together).
What is AB in math?
A-B is the set of all elements that are in A but NOT in B, and B-A is the set of all elements that are in B but NOT in A. Notice that A-B is always a subset of A and B-A is always a subset of B.
How do you solve AB sets?
To find the difference A – B of these two sets, we begin by writing all of the elements of A, and then take away every element of A that is also an element of B. Since A shares the elements 3, 4 and 5 with B, this gives us the set difference A – B = {1, 2}.
How do you solve log ab?
log(a/b) = log a -log b, a > 0, b > 0. log an = n (log a) (Logarithm of a power). logx y = logmy / logmx (Change of base rule). logx y = 1 / logy x .
What is coefficient math?
A coefficient is a number multiplied by a variable. Examples of coefficients: In the term 14 c 14c 14c , the coefficient is 14. In the term g, the coefficient is 1.
Is 10 an algebraic expression?
For example, 10x + 63 and 5x – 3 are examples of algebraic expressions. For example, x is our variable in the expression: 10x + 63. The coefficient is a numerical value used together with a variable. For example, 10 is the variable in the expression 10x + 63.
What is the coefficient of x2?
It is usually an integer that is multiplied by the variable next to it. The variables which do not have a number with them are assumed to be having 1 as their coefficient. For example, in the expression 3x, 3 is the coefficient but in the expression x2 + 3, 1 is the coefficient of x2.
What is a multiplication number sentence?
A multiplication sentence is a number sentence used to express multiplication. In a multiplication sentence, the second factor is referred to as the multiplicand. It is the number that is multiplied by the first factor, referred to as the multiplier.
What are mathematical equations?
In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value. The most basic and common algebraic equations in math consist of one or more variables.
What is the y-intercept of Y 5?
Answer and Explanation: The y-intercept of y=5 is 5. Since the equation y=5 provides a constant value of y this creates a horizontal line on a graph and therefore crossing the y-axis at 5.
What is the y-intercept in the given equation 4x y =- 5?
x -intercept is 54 and y -intercept is 5 .
What does Y 4x 5 mean?
Explanation: y=4x−5 is in the form of the slope-intercept formula for a linear equation, y=mx+b , where m is the slope and b is the y-intercept. By definition, the y-intercept is −5 . To find the x-intercept, make y equal to zero and solve for x .
