Fred. .9 is larger than .6 therefore, Fred walked a longer distance.
To multiply a number by 10, move the decimal point to the right one place value.
10*0.019=0.19
First, you replace x with -3.
It will look like -3/3.
Then you divide and get -1.
F'(x, y) = 14x +xydy/dx + 14ydy/dx = 0
(xy+14y)|dy/dx = -14x
dy/dx = -14x /(xy+14y)
dy/dx |(x=1,y=1) : -14(1) / (1+14) = -14/15
using
y-y1=/x-x1 = -14/15
y-1/x-1 = -14/15
15y-15 = -14x+14
15y+14x -15-14=0
14x +15y = 29
He needs 6 fraction pieces to make a full circle
