Answer:
y=(-4/3)x
Step-by-step explanation:
you put the points into this equation to find the slope
(y2-y1)/(x2-x1)
now lets label the points
(6,-8)
x1=6 and y1=-8
(3,-4)
x2=3 and y2=-4
Input into equation
(-4-(-8))/(3-6)=
(-4+8)/(3-6)
4/-3
Answer:
250ft
Step-by-step explanation:
45ft + 45ft of fencing for the two short ends. 80ft +80ft for the two long sides
45ft+45ft=90ft
80ft+80ft=160ft
90ft+160ft=250ft
Answer:
$34
Step-by-step explanation:
I'd work backwards.
For the third book, she paid all her remaining money. The problem says she paid "1/2 her leftover money + $3". This means that: (let m = money used to buy book 3)
m = 1/2m + 3
1/2m = 3
m = 6
For the second book: (let n = money before book 2)
n - m (money left after book 2) = 1/2n + 2
1/2n +2 is money used up for book, which is the same as n-m.
n = 1/2n + 2 + m
1/2n = 2 + m = 2 + 6
1/2n =8
n = 16
For the first book, she spent 1/2 her money + 1. If o = money before book 1 (or the whole allowance):
o - n = 1/2o + 1
o = 1/2o + n + 1 = 1/2o + 16 + 1
1/2o = 17
o = 34
Check!
Spent 17 (half 34) + 1 on book 1
16 left
Spent 8 (half 16) +2 on book 2
6 left
Spent 3 (half 6) + 3 on book 3
0 left
