Which of these is an example of a literal equation?A.3x – 4y
B.12 = 9 + 3x
C.6 + 30 = 62
D.ax – by = k

Answers

Answer 1
Answer:

ANSWER

ax-by=k is an example of literal equation.

EXPLANATION

A literal equation is an equation in which letters or variables are used to represent real values.

A literal equation consists of at least two letters or variables.

The first option consists of two variables but it is not an equation. It is just an expression.


The second option is not a literal equation because it consists of only one variable. This is  just a linear equation in one variable. But a literal equation should have at least two variables or letters.

As for the third option, it does not even contain a variable or letter.
Answer 2
Answer: Choice D. represents a literal equation

Answer:

The distance between A and B is 2.6

Step-by-step explanation:

We know that there are 2 whole numbers from -1 to 0 and 0 to 1. Then we can add the 0.3 from both sides. 0.3 plus 0.3 is 0.6.

Answer:

  • W = 55°
  • X = 125°
  • Y = 110°
  • Z = 70°

Step-by-step explanation:

Corresponding angles in similar figures are congruent. Corresponding angles are listed in the same order in the similarity statement.

  ∠A = ∠W = 55°

  ∠B = ∠X = 125°

  ∠C = ∠Y = 110°

  ∠D = ∠Z = 70°

Find the product of (x + 5)(x − 5).x2 − 10x + 25

x2 − 25

Answers

x^2 -25
All I did was divide both and I got the answer.

Answer:  x^2 - 25


Explanation:

Here is a tip/ shortcut to multiplying binomials in the (a + b)(a - b) format.

The only things you have to look for is the factor of a * a and the factor of       b * b.

The reason being, a * -b and b * a cancel each other out no matter what.

For example

1. (x + 5)(x - 5)         Multiply x_(1) by x_(2)

  x * x = x^(2)

2. (x + 5)(x - 5)         Multiply x_(1) by -5 in the second binomial

  x * -5 = -5x

3. (x + 5)(x - 5)        Multiply 5 in the first binomial to x_(2)

  5 * x = 5x

4. (x + 5)(x - 5)        Multiply 5 in the first binomial to -5 in the second binomial

  5 * -5 = -25

5. Now that you have all of your answers, write your equation, in order, to look like this.

x^(2) - 5x + 5x - 25

6. -5x and 5x cancel each other out when combining like terms so you're left with.

x^(2) - 25


In the end, steps 2, 3, 5, and 6. can be taken out by doing this.

Just multiply x_(1) by x_(2) to get x^(2)

Then just multiply 5 in the first binomial to -5 in the second binomial to get -25

Then write your answer.

x^(2) - 25


This works because there is no need for steps 2,3,5, and 6 since they lead to the same outcome from doing steps 1 and 4.
