Answer:

Mary worked 7 and a half hours.

Step-by-step explanation:

The easiest way to solve this is converting to the 24 hours metric.

In this metric, 8:10 am is 8h, 10 min.

3:45 pm is 12+3 = 15h, 45 min.

Rounded to the nearest quarter hour, Mary worked 15-8 = 7h, 45-10 = 35 min, Mary worked 7 and a half hours.

First we count how many hours is inbetween 8 and 3  which is 7

then subtract 10 for the first time

6:50 then add 45 for the second time

7:35

round down so she worked 7 1/2 hours

What is equation of the line that passes through the point (-3,8) and has an undefined slope
aniked [119]

The equation of line that passes through point (-3, 8) and has an undefined slope is x = -3

<u>Solution:</u>

Given that we have to find the equation of line that passes through point (-3, 8) and has an undefined slope

Since the line has an undefined slope. This informs us that it is a vertical line parallel to the y-axis and passing through all points in the plane with the same x-coordinate.

If the slope of the line is undefined, then, by definition the line is a vertical line.

For a vertical line, the value of  x  is the same for each and every value of  y

Given point is (x, y) = (-3 , 8)

Because the value of  x  in the point provided in the problem is -3, we get

Equation of line is : x = -3

81+7x=81 what does x equal?
cupoosta [38]
So to start off here is the question being asked:
<span>81+<span>7x</span></span>=<span>81
</span>The first thing we are going to do is s<span>implify both sides of the equation:
</span><span><span>7x</span>+81</span>=<span>81
</span>Second thing to do is s<span>ubtract 81 from both sides so:
</span><span><span><span>7x</span>+81</span>−81</span>=<span>81−<span>81
</span></span>The final thing to do is d<span>ivide both sides by 7:
</span><span><span>7x/</span>7</span>=<span>0/<span>7
The final answer is:
x=0

I hope this helps! :)</span></span>
