What is the simplified expression for Negative 3 c d minus d (2 c minus 4) minus 4 d?
Sindrei [870]

Answer:

-5cd

Step-by-step explanation:

<u>Simplifying:</u>

  • -3cd - d(2c - 4) - 4d =          ⇒ parenthesis
  • -3cd - 2cd + 4d - 4d =         ⇒ simplify like terms
  • -5cd                                     ⇒ answer

The first choice is correct one.

Find an equation of the line that passes through the point (7,0) and is parallel to 7y=6x-14
aksik [14]

Answer:

  • y = 6/7 x - 6    Your answer could be
  • y = 0.857 x - 6

Step-by-step explanation:

Remark

  • Start by solving for y. Divide both sides by 7
  • y = 6/7 x - 14/7
  • y = 6/7 x - 2
  • Parallel lines all have the same slope. What you know so far is that the slope of the new line must be 6/7
  • y = 6/7x + b
  • Now you use the given point to solve for b

Givens

  • x = 7
  • y = 0

Solution

  • 0 = 6/7 * 7 + b     Reduce the fraction
  • 0 = 6 + b             Subtract 6 from both sides
  • -6 = 6 -6 + b
  • b = - 6

Answer

  • y = 6/7 x - 6    Your answer could be
  • y = 0.857 x - 6
