(−8* y^2−9*y)+(8*y^3+9*y^2−2*y)
first, remove extraneous parentheses (or distribute if negative)
=−8* y^2−9*y+8*y^3+9*y^2−2*y
then group terms in decreasing degree of y (variable)
=+8*y^3 −8* y^2+9*y^2 −9*y−2*y
simply expression by adding/subtracting similar terms
=+8*y^3 +y^2 −11*y
to give the final answer.

Multiple Choice Suppose y varies directly as x. if y = 5 when x=8, find y when x=64

Juliette [100K]

Answer:

Step-by-step explanation:

y∞x

then

y=kx (with k as constant)

y=5 when x=8

⇒Putting this in the first equation

⇒5=k×8

⇒k=5/8

Now

y=? when x=64

Putting x=64 in the first equation

y=kx

⇒y=(5/8)×64

We get

y=40

Hope u understand

Answer:

The correct answer is: Option D) 5

Step-by-step explanation:

Given equation is:

$3(x + 2) + x = 2x + 16$

In order to find that which values of x makes the equation true, we have to put each value of x in the equation. When both sides of equations will be equal, that value of x will be true for the equation.

Putting x = 2

$3(2 + 2) + 2 = 2(2) + 16\\3(4)+2 = 4+16\\12+2 = 20\\14 \neq 20$
