Once you simplify it you get 5x-168f-224fx-z
Answer:
B. 2
Step-by-step explanation:
Assuming the term is meant to look like this: -3x², then the answer is B.2. An exponent is a superscript (super means above, script means writing) that tells you to multiply something by itself.
In this case, -3x² means -3·x·x
If it was written as (-3x)², it would mean (-3x)·(-3x)

First 40 hours rate = $12 per hour.
Next 10 hours charge ( Upto 50 hours) = A half of $12 that is $6 per hour.
And after next 10 hours chrges ( More than 50 hours) = 2 times of initial rate, that is 2*12 = $24 per hours.
Let us take variale x for number of hours and f(x) is the function for total earning for x hours.
So, we can setup a piecewise function as
Therefore,
70 hours can be divided into = 40 hours + 10 hours + 20 hours.
Total earning of 70-hour week = 12* 40 hours + 6 * 10 hours + 24*20 hours
= 480 + 60 + 480
= $1020.
Therefore, he earn $1020 for a 70-hour week.
Recall that 1 hundred-thousandth in scientific notation is:
Now, 19 hundred-thousandths is 10 one hundred-thousandths added to 9 one hundred-thousandths which is:
Simplifying the above sum we get:
