What is the answer for |x|=9
Maru [420]

The absolute value |x| returns the "positive version" of a number.

In other words, if the number is positive, it remains positive; if the number is negative, it changes sign.

So, if we want |x|=9, we want the "positive version" of x to be 9.

This can happen in two ways: if x is already 9, then its absolute value is still nine. If instead x=-9, its positive value will be 9 again.

In formula, we have

|x|=9 \iff x=\pm 9

because

|9|=9,\quad |-9|=9

Please help me I have a test tomorrow
yarga [219]

#5 is very nicely and correctly done.

#7 says: "No matter what X may be, this function of it is always 9 more than 1/2 of X .".

That's a very powerful statement. Now you know that if X is ever 2, the function will be 1/2(2)+9 which is 10.

If X is ever zero, the function will be 1/2(0)+9 which is 9. If X is ever a cow, the function will be 1/2 of a cow, plus the number 9. Which makes no sense, but that's what the function says.

So, when X is -8, the function is 1/2 of -8, plus 9. Which is 5 ... the 'f' of -8.

Whatever X happens to be at the moment, just write that number in place of X in the function, and it'll show you the function of what X is.

f(a bazillion) = 1/2(a bazillion) + 9 .

f(a-28) = 1/2(a-28) + 9 (but simplify it)

Does anyone understand atleast one of them
pickupchik [31]

Answer:

Look in explanation.

Step-by-step explanation:

1. 76543^{-4} is the same as \frac{1}{76543^{4} } because since there is a negative exponent, you would want to flip the reciprocal and change the negative to positive.

The rest are very similar to this.
