Answer:
(5 - y) ^3 = 125 - 75y + 15y^2 - y^3
Step-by-step explanation:
Binomial expression
1
1. 1
1. 2. 1
1. 3. 3. 1 --------power of 3
( 5 - y) ^3
( 5 - y) (5 - y) (5 - y)
( a + b) ^3 = a^3 + 3a^2b + 3ab^2 + b^3
a = 5
b = -y
( 5 - y) ^2 = ( 5 - y) (5 - y)
= 5( 5 - y) - y(5 - y)
= 25 - 5y - 5y + y^2
=(25-10y+y^2)
( 25 - 10y + y^2)( 5 - y)
= 5(25 - 10y + y^2) - y( 25 - 10y + y^2)
= 125 - 50y + 5y^2 - 25y + 10y^2 - y^3
Collect the like terms
= 125 - 50y - 25y + 5y^2 + 10y^2 - y^3
= 125 - 75y + 15y^2 - y^3

If you put into a calculator "Sin(6)+Cos(6)+3Sin(2)Cos(2)", you get 1.20368506925. Hope that helps
Answer:
Step-by-step explanation:
y/2 - 4 = x/3 can also be written as 1/2y - 4 = 1/3x
slope intercept form is y = mx + b
1/2y - 4 = 1/3x....multiply entire equation by 6, to get rid of fractions
3y - 24 = 2x ...add 24 to both sides
3y = 2x + 24....divide both sides by 3
y = 2/3x + 6 <===
