Are the graphs of the equations parallel, perpendicular, or neither?x -3y = 6 and x - 3y = 9
seraphim [82]

The equation of a line in Slope-Intercept form, is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

By definition:

- The slopes of parallel lines are equal and the y-intercepts are different.

- The slopes of perpendicular lines are opposite reciprocals.

For this case you need to rewrite the equations given in the exercise in Slope-Intercept form by solving for "y".

- Line #1:

\begin{gathered} x-3y=6 \\ -3y=-x+6 \\ y=\frac{-x}{-3}+(\frac{6}{-3}) \\  \\ y=\frac{x}{3}-2 \end{gathered}

You can identify that:

\begin{gathered} m_1=\frac{1}{3} \\  \\ b_1=-2 \end{gathered}

- Line #2:

\begin{gathered} x-3y=9​ \\ -3y=-x+9 \\ y=\frac{-x}{-3}+(\frac{9}{-3}) \\  \\ y=\frac{x}{3}-3 \end{gathered}

You can identify that:

\begin{gathered} m_2=\frac{1}{3} \\  \\ b_2=-3_{}_{} \end{gathered}

Therefore, since:

\begin{gathered} m_1=m_2 \\ b_1\ne b_2 \end{gathered}

You can conclude that: The graphs of the equation are parallel.

A boat goes downstream from one place to another in 9 hours. It covers the same distance upstream in 11 hours. If the speed of t
Evgen [1.6K]

Answer:

198 km

Step-by-step explanation:

The speed of the boat supposed to be x km/h

(x+2)*9 = (x-2)*11

9x + 18 = 11x – 22

2x = 40

X = 20

Distance between 2 places: (20 + 2) * 9 = 198 km

Or (20 – 2 ) * 11 = 198 km
