Simplify |x| - |-x|.

Mathematics
1 answer:
Verdich [7]3 years ago
5 0

Answer:

0

Step-by-step explanation:

Two cases: if x\ge0

|x| - |-x| = x - x= 0

Instead if x

|x| -|-x| = -x -(-x)=-x+x=0

Alternatively you can try to graph both f(x) = |x|; g(x)=|-x| and checking the vertical distance between the two graphs

If x = 1 is a zero of the polynomial function f(x) = 3x3 − 8x2 + 3x + 2, which of the following is another zero of f(x)? 
zubka84 [21]
Divide 3x^3 -8x^2+3x  + 2 by (x - 1)

THis gives the quotient   3x^2 - 5x - 2

3x^2 - 5x -  2  = (3x + 1)(x  - 2 )


so x = 2 is another root  


Its  the first choice

Hakeem puts $59 from each paycheck into his saving account. He gets paid every two weeks or 26 times per year. His goal is to sa
Mashutka [201]

Answer: Yes, He will.

Step-by-step explanation:

Here, the amount he puts in each week = $ 59

In one year the number of weeks = 26

Thus, the total amount he can save in one year = 59\times 26 = 1534

According to the question,

His total saving in one year ≥ 1500

Since,    1534 > 1500

Thus, he will reach his goal.

You used p minutes one month on your cell phone. The next month you used 75 fewer minutes. Simplify the expression.
Anestetic [448]
Hi there!

Let's assume that one month is represented by the variable 'm', the amount of minutes you started with is 's', and minutes you spent is 'p'.

So, one month can be represented as 'm=s-p'.

The next month is a bit more tricky. This will incorporate 75 less minutes into the equation. 'm=s-75' can be used to represent this, as we assume that you didn't use any minutes in the first month, and that p=75 in this case.

If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer. I want to be able to assist more users one-on-one, as well as to move up in rank! :)
