Answer:

The answer is number 3.

Step-by-step explanation:

To get n by itslef, you have to divide -9 by both sides of the equation, however, since the -9 is in-between the two lines on the outside of it, it is therefore an absolute number. Usually when you divide both sides of an equation like this by a negative number, you would flip the less than symbol (>), but since the -9 is an absolute number, the negative does not count for anything. When you divide 63 by 9, you do not have to flip the less than symbol.

- Hope this helps.

Joe can clear a lot in 2.5 hours. His partner can do the same job in 7.5 hours. How long will it take them working together?
irina [24]

Answer:

The time required by both persons to complete the work T = 1.458 hours

Step-by-step explanation:

Given data

Time required by Joe to clear a lot T_1 = 2.5 hours

Time required by his partner to clear a lot T_2 = 2.5 hours

Time required by both persons to complete the work by working together

T = \frac{T_1 T_2}{T_1 + T_2}

T = \frac{(2.5)(3.5)}{2.5 + 3.5}

T = 1.458 hours

Therefore the time required by both persons to complete the work T = 1.458 hours

Find the slope between the points (6, 8) and (6, 6)
Goryan [66]

Answer:

<em>m</em> = 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>

<em>Identify</em>

Point (6, 8)

Point (6, 6)

<u>Step 2: 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{6-8}{6-6}
  2. [Fraction] Subtract:                                                                                           \displaystyle m = \frac{-2}{0}
  3. Simplify:                                                                                                             <em>m</em> = undefined

∴ We have a vertical line at x = 6.
