Operations with variables can give you excluded values by making the denominator equal to zero.

Ex. 48/60 always equals to 4/5 but 4x/6x is not always equal to 2/3 because when you make x equal to zero it makes the equation invalid.

W<br> Evaluate the following expressions for x = 2.<br> -9.2(4 – x)<br> -9.2(4 - (2)<br> -9.2(2)
Fed [463]

Answer:

- 18.4

Step-by-step explanation:

The given expresion is

- 9.2(4 - x)

We want to evaluate this expression for x=2.

We substitute x=2 into the expression.

This means that, we will put 2 wherever we see x in the given expresion.

This will give us:

- 9.2(4 - 2)

Simplify the parenthesis

- 9.2(2)

=  - 18.4

An auction website charges $1 for a bid. The bidding starts at 1¢ and goes up 1¢ at a time. A television that is worth $2000 is
SCORPION-xisa [38]
This is fairly complex, but looks like fun. 
So first lets count how many bids are made till the bidding goes up to 160.
That is 100*160=16000
How much will be your random bid. Each bid has equal chance so it is the avarge of all bids. (1cent + 160dollars)/2 = 80dollars (rounded)
What is your chance of winning: 1 bid wins out of 16000 so 1/16000.
When you win your profit is 2000-80dollars=1920
1920/16000= 0.12 dollars 
You entering the bidding costs 1 dollar and your average win is 0.12
This the outcome is 0.12-1=-0.88 dollars

Can someone please help asap?<br> find f(-4) if f(x) = x2 - x
Marianna [84]

Answer:

20

Step-by-step explanation:

Given function f(x)=\[x^{2}-x\]

We need to find f(-4) which means we need to find the value of the function when x=-4 .

On substituting x=-4 in the given function:

f(-4)=\[-4^{2}-(-4)\]

Square of -4 is 16.

Hence, f(-4)=\[16+4\]

=20

Hence the value of the given function f(x)=\[x^{2}-x\] when x=-4 is 20.

I can answer the slopes

Answer:

1. would have a slope of 2

2. would have a slope of -1.66

3.would have a slope of 0

4. would have a slope of -13

Step-by-step explanation:

(Y2 - Y1) / (X2 -X1)

1. (9-5) / (4-2) = 4 / 2 =2

2. (-5-5) / (3 - -3) = -10 / 6 = 1.66

3. (2 - 2) / (5 - -4) = 0 / 9 = 0

4. (-7 - 6) / (3 - 3) = -13 / 0 = -13
