From 8:25 am to 30 seconds past 8:29 am, there are 4.5 minutes. Her speed is calculated by dividing the distance of the post office from her house by the time.

Speed = 0.75 mile / 4.5 minutes = 1/6 mile / minute

Determining the number of minutes she will have to take in order to reach school,

Time = 3.42 mile / (1/6 mile/minute) = 20.52 minutes

Adding this to the initial time,

Final time = 8:25 am + 20.52 minutes

= 8:45 am and 31.2 seconds.

She will reach the school on time even without increasing her speed.

Find an equation perpendicular to x=1 and passing through (8,-9)

valina [46]

Answer:

$y=-9$

Step-by-step explanation:

We want to find an equation of a line that's perpendicular to x=1 that also passes through the point (8,-9).

Note that x=1 is a vertical line since x is 1 no matter what y is.

This means that if our new line is perpendicular to the old, then it must be a horizontal line.

So, since we have a horizontal line, then our equation must be our y-value of our point.

Our y-coordinate of our point (8,-9) is -9.

Therefore, our equation is:

$y=-9$

And this is in standard form.

And we're done!
