Place the correct symbol, < or >, between the two numbers 11/18 17/24
evablogger [386]

For this case we must indicate the correct sign between the following numbers:

\frac {11} {18}\ and\ \frac {17} {24}

We have to:

\frac {11} {18} = 0.611111111111\\\frac {17} {24} = 0.708333333333

So, we have to \frac {17} {24}> \frac {11} {18}

Answer:

\frac {17} {24}> \frac {11} {18}

Write an equation for the line that passes through the given point and is perpendicular to the graph of the given equation.
Nezavi [6.7K]

Answer:

  • y + 2 = - 3/2(x - 4)

Step-by-step explanation:

<u>Given line:</u>

  • y + 4 = 2/3(x - 2)

It has a slope of 2/3.

<u>Perpendicular lines have negative-reciprocal slopes, so the perpendicular slope is:</u>

  • m = - 3/2

<u>Find its equation provided it passes through the point (4, - 2):</u>

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