Answer: She ran 0.25 laps a minute
Step-by-step explanation:
Every minute she runs 0.25 a minute which means that every 4 minutes she runs 1 lap which means if she run for 8 minutes she gets 2 laps
Answer:
4/7
Step-by-step explanation:
32/56 = 4/7
Answer:
see below
Step-by-step explanation:
In the attachment, the points are listed in the order given in the problem statement. (They are listed to the right of the "rotation matrix", with x-coordinates above y-coordinates.)

I really don't like to do repetitive calculations, so I try to use a graphing calculator or spreadsheet whenever possible. Angles are measured CCW.
As always, the rotation transformations are ...
180° — (x, y) ⇒ (-x, -y)
270° — (x, y) ⇒ (y, -x)
Answer:
y+20 = 9(x+2)
Step-by-step explanation:
The slope that passes through the points is
m = (y2-y1)/(x2-x1)
= (79- -20)/ (9--2)
= (79+20)/(9+2)
= 99/11
= 9
We can use point slope form to write an equation. It says to use the first point.
y-y1 = m(x-x1)
y--20 = 9(x--2)
y+20 = 9(x+2)
