Answer:
The least whole number is the number 1
Step-by-step explanation:
we have

Remember that
<u>Whole numbers</u> are positive numbers, including zero, without any decimal or fractional parts [0,1,2,3,4,5,6,...]
so
Solve the inequality for x
Divide both sides by 400


Rewrite

therefore
The least whole number is the number 1
for the value of
we have the function f(x) = 1/(x-2) or
as undefined or not defined .
<u>Step-by-step explanation:</u>
<u>Function undefined: </u> A function is undefined when it gives results which are not defined for example , infinity .
Here we have , Function f(x) = 1/(x-2) or
. We need to find a value of for which this is not defined . Let's find out:
We can clearly see that it's a fractional function with numerator as 1 and denominator as x-2 . For a fractional function to be undefined it's denominator must be zero i.e. x-2 = 0 or 
⇒ 
⇒ 
⇒ 
Therefore, for the value of
we have the function f(x) = 1/(x-2) or
as undefined or not defined .
The value of f(8.6) is -5.
Given that
If f(x) = − 5,
We have to determine
What is f(8.6)?
According to the question
This function is independent of x.
There is no term associated with x on the function.
f(x) = − 5,
The given is not dependent on the variable it is an independent function.
Then,

Hence, the value of f(8.6) is -5.

I don't really get your question. But if you save the same amount each week. The amount of money will be the amount you save each week multiplied by the number of weeks
Answer:
The value of 7w - 8 is -22
Step-by-step explanation:
Let us solve the question
∵ -4w - 5 = 3
→ Move -5 from the left side to the right side by adding both sides by 5
∴ -4w - 5 + 5 = 3 + 5
∴ -4w = 8
→ Divide both sides by -4
∵
= 
∴ w = -2
→ Now let us find the value of the given expression
∵ The given expression is 7w - 8
→ Substitute w by -2 to gets its value
∴ 7w - 8 = 7(-2) - 8
∴ 7w - 8 = -14 - 8
∴ 7w - 8 = -22
∴ The value of 7w - 8 is -22
