4y - y(3 - 7y) + 5 + 2(8 - y)

<u>Step 2: Simplify</u>

  1. [Distributive Property] Distribute parenthesis:                                               4y - 3y + 7y² + 5 + 16 - 2y
  2. Combine like terms (y):                                                                                    7y² - y + 5 + 16
  3. Combine like terms:                                                                                         7y² - y + 21

Which steps should be used to graph the equation below? y-4=1/3(x+2)
juin [17]

-> First, we want to put it into more of a slope-intercept form so we can graph.

y - 4 = 1/3 (x + 2)

y = 1/3 (x + 2) + 4

y = 1/3x + 2/3 + 4

y = 1/3x + 14/3

-> Next, we will plot the point (0, 14/3) because it is the y-intercept of our equation

-> Last, we will move up one and to the right three, following the pattern of "rise over run" with our slope of 1/3

       [] The finished graph is attached

       [] I have also graphed the original equation to show that they overlap, showing that our simplification works

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
