Answer:
4:1
Step-by-step explanation:
x+20 : y+20 = 5 : 2
(x+20)/(y+20) = 5/2
2(x+20) = 5(y+20)
2x+40 = 5y+100
2x = 5y+60 (1)
x-5 : y-5 = 5:1
(x-5)/(y-5) = 5/1
x-5 = 5(y-5)
x-5 = 5y-25
x = 5y-20 (2)
Solve (1) & (2) simultaneously,
2(5y-20) = 5y+60
10y-40 = 5y+60
5y = 100
y = 20
x = 5y-20
x = 5(20)-20 = 100-20
x = 80
x:y
80:20
4:1
Plug in -1 for x and work it ou'
g(-1) = (-1)^3 + 6(-1)^2 + 12(-1) + 8
= -1 + 6 - 12 + 8
= 1
Answer:
2/3 b +1/3 a
Step-by-step explanation:
b+ 1/3(-b+a)
= b - 1/3b + 1/3a
= 2/3 b +1/3 a
