Answer:

x = -1

Step-by-step explanation:

\frac{2}{3} - 4x + \frac{7}{2} = -9x + \frac{5}{6}

Add 4x to each side of the equation

\frac{2}{3} - 4x + \frac{7}{2} + 4x = -9x + \frac{5}{6} + 4x

\frac{2}{3} + \frac{7}{2} = -9x + \frac{5}{6} + 4x

Subtract ⅚ from each side

\frac{2}{3} + \frac{7}{2} - \frac{5}{6} = -9x + \frac{5}{6} + 4x - \frac{5}{6}

\frac{2}{3} + \frac{7}{2} - \frac{5}{6} = -9x + 4x

\frac{4 + 21 + 5}{6} = -5x

\frac{30}{6} = -5x

5 = -5x

Divide both sides by -5

\frac{5}{-5} = \frac{-5x}{-5}

-1 = x

x = -1

IgorC [24]

Answer: Choice C

\begin{array}{|c|c|} \cline{1-2}x & y\\\cline{1-2}0 & 1\\\cline{1-2}2 & 2\\\cline{1-2}4 & 3\\\cline{1-2}6 & 4\\\cline{1-2}\end{array}

=========================================================

Explanation:

There are four marked points on the line.

Each point is of the form (x,y)

  • The first or left most point is (0,1)
  • The second point is (2,2)
  • The third is (4,3)
  • The fourth is (6,4)

Each of these points is then listed in the table format as shown above.

There are infinitely many other points on the line; however, we only select a few of them to make the table (or else we'd be here all day).

Extra side notes:

  • The slope of this line is m = 1/2 = 0.5
  • The y intercept is 1 located at (0,1)
  • The equation of this line is y = 0.5x+1
