This expression is the difference of two cubes:
x^3 y^3
----- - -------
2^3 3^3
The rule here is a^3 - b^3 = (a - b)(a^2 + ab + b^2), so
x^3 y^3 x^2 x^3y^3 y^2
----- - ------- = (x/2 - y/3)*(-------- + ----------- + --------- )
2^3 3^3 2^2 6^3 3^2
Answer:
y-3=14/17(x-2)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(17-3)/(19-2)
m=14/17
y-y1=m(x-x1)
y-3=14/17(x-2)

Answer:
$10,000
Step-by-step explanation:
Let b represent the amount invested in bonds. Then 50,000 - b wil be the amount invested in stocks. Molly's total return is ...
0.15b + 0.18(50000-b) = 8700
-0.03b +9000 = 8700 . . . . simplify
300 = 0.03b . . . . . . . . . . . . add .03b-8700
10,000 = b . . . . . . . . . . . . . divide by 0.03
Molly invested $10,000 in bonds.
