I believe the answer would be 11.99, because 20% times 59.95 is 11.99
Answer: its 9 units ok yea
Answer:
1) Slope= 2, y-intercept=4, equation: y=2x+4
2.Slope= -10 , y-intercept= 60 , equation: y=-10x+60
Step-by-step explanation:
Slope formula: 
1. Plug in two sets of cordinates into the equation
(0,2) (2,8)
2. Solve, slope =2
3. Plug in one pair into the point slope formula
Point slope formula: 
4. y-8=2(x-2)
5.y-8=2x-4
6. y=2x+4
Do the same for the other equation
39 foot into 3 pieces
one is 13 feet
the other pieces add up to the
remaining wire
which is 39-13=26 so
the two remaining pieces are x and y
one must be 2 less than 3 times the
other
x must be 2 less than 3 times the y
x=-2+3y
x=3y-2
x+y=remaining=26
26=x+y
x=3y-2
subsitute
26=3y-3+y
add like terms
26=4y-2
add 2 to both sides
28=4y
divide by 4
7=y
subsitute
7+x=26
subtract 7
x=19
19>7
7 feet is the legnth of the shorter
piece
