Answer:

Naomi gives some of her six pencils away

Six servings of dinner were decreased by a number

Gabrielle decreased her 6-minute mile by an unknown amount of time

Step-by-step explanation:

Verify each case

Part 1) Naomi gives some of her six pencils away

Let

x -----> some of Naomi's six pencils

The algebraic expression that represent this situation is

6-x

therefore

This situation can represent the given expression

Part 2) Sydney increased her collection of coins by six

Let

x -----> the number of coins in Sydney's collection

The algebraic expression that represent this situation is

x+6

therefore

This situation cannot represent the given expression

Part 3) Benjamin lost six of his stickers

Let

x -----> the number of stickers that Benjamin has

The algebraic expression that represent this situation is

x-6

therefore

This situation cannot represent the given expression

Part 4) Six servings of dinner were decreased by a number

Let

x -----> the number

The algebraic expression that represent this situation is

6-x

therefore

This situation can represent the given expression

Part 5) Westville has 6 fewer schools than Eastville

Let

x -----> the number of schools Eastville has

The algebraic expression that represent the number of schools Westville has is

x-6

therefore

This situation cannot represent the given expression

Part 6) Gabrielle decreased her 6-minute mile by an unknown amount of time

Let

x -----> an unknown amount of time

The algebraic expression that represent this situation is

6-x

therefore

This situation can represent the given expression

Consider a steel ball floating on the surface of mercury in a half-filled container. What happens when the rest of the container

Helen [10]

Answer

The steel ball will be caught up in between the mercury and water medium.

Step-by-step explanation:

Mercury with a density of 13546 kg/m^3

water with a density of 1000 kg/m^3
Steel with a density of 8050 kg/m^3

From the factual density of both substances given above ,it shows that mercury is more heavier than water. In that case mercury will be at the lower layer when mixed with water.

The steel ball will be caught in between both mixtures as the density of steel is 8050 kg/m^3.Which is more than Water but less than Mercury.

Is (x+7) a factor of f(x) x3-3x2+ 2x-8?

Snowcat [4.5K]

Answer:

(x+7) is not a factor

Step-by-step explanation:

we know that

If (x+7) is a factor of f(x)

then

For $x=-7, f(-7)=0$

Verify

we have

$f(x)=x^{3}-3x^{2} +2x-8$

Substitute x=-7

$f(-7)=(-7)^{3}-3(-7)^{2} +2(-7)-8$

$f(-7)=-343-147 -14-8$

$f(-7)=--512$

$-512\neq 0$

therefore

(x+7) is not a factor
