Which polynomial is equivalent to (x^3+2x^4+5x^5-2x-1)-(-7x-x^2+9x^3+2x^4)?
podryga [215]

Answer:

The correct answer is option B.

5x⁵ + -8x³ + x² + 5x -1

Step-by-step explanation:

It is given that,

(x³ + 2x⁴ + 5x⁵ - 2x - 1) - (-7x - x² + 9x³ + 2x⁴)

<u>To find the subtraction result</u>

(x³ + 2x⁴ + 5x⁵ - 2x - 1) - (-7x - x² + 9x³ + 2x⁴)

 = x³ + 2x⁴ + 5x⁵ - 2x - 1 + 7x + x² - 9x³ - 2x⁴)

 = 5x⁵ + 2x⁴ - 2x⁴ + x³ - 9x³  + x²- 2x + 7x -1

 = 5x⁵ + -8x³ + x² + 5x -1

The correct answer is option B.

5x⁵ + -8x³ + x² + 5x -1

What is an equation of the line that passes through the points (5, 5) and (5, -8)
Luden [163]

Answer:

m = undefined

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right<u> </u>

<u>Algebra I</u>

  • Coordinates (x, y)
  • Slope Formula: \displaystyle m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (5, 5)

Point (5, -8)

<u>Step 2: Identify</u>

(5, 5) → x₁ = 5, y₁ = 5

(5, -8) → x₂ = 5, y₂ = -8

<u>Step 3: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

  1. Substitute in points [Slope Formula]:                                                             \displaystyle m=\frac{-8-5}{5-5}
  2. [Slope] Subtract:                                                                                               \displaystyle m=\frac{-13}{0}

Here we see that we have a number divided by 0. Since we know that we cannot divide any number by 0, our slope will be undefined. This will be a vertical line on a Cartesian plane of x = 5.
