What is the area of a triangle with vertices at (-3 3) (-3,2) and (1,2)?
d1i1m1o1n [39]
This is a right triangle, so first find the distance between the two legs...

Points where the numbers are the same indicate a point that is on the same axis as the other

(-3, 3) and (-3, 2) have a distance of 1


(-3,2) and (1,2) have a distance of 4

The area formula for a triangle is 1/2bh and in this case 1/2(1)(4) = 2

The area is 2

Find the equation of the perpendicular bisector of a line segment whose end points are (-3,9) and (-1,5)
timofeeve [1]

First find the equation of y.

y=mx+n=\frac{\Delta y}{\Delta x}x+n

Find the slope m.

m=\frac{5-9}{-1-3}=\frac{-4}{-4}=1.

Pick one point, I'll pick (-3, 9). Insert coordinates in equation then compute n.

9=1(-3)+n\implies n=12.

The equation of a line y is:

y=x+12.

The perpendicular line y_{\perp} is same like the normal line except its slope m becomes:

k=-\frac{1}{m}=-1.

The equation of a perpendicular bisector is thus:

y_{\perp}=-x+12.

Hope this helps.

Mabel spends 444 hours to edit a 333 minute long video. She edits at a constant rat\\\\\\\\\\\\\\e. How long does Mabel spend to
mestny [16]
Mabel spends 4 hours editing a 3 minute video. she edits at a constant rate. how long does mabel spend to edit a 9 minute video?

she spends 4 hours on a 3 minute video
so there are 60 minutes in an hour
4 hours with 60 minutes- 4x60=240
so she spent 240 minutes on a 3 minute video
3 divided by 240
3/240= 0.0125
so her constant rate is 0.0125 minutes an hour
so divide 9 minutes by her constant rate
9/0.0125 = 720
so she spends 720 minutes on a 9 minute video.
divide 720 by 60 since there are 60 minutes in an hour
720/60 = 12
so she spends 12 hours on a 9minute video
