Answer:
2.7, or 2
, or 
Step-by-step explanation:
You would know 4×5=20 so just add 2 more zeroes cause there is a zero in 40 and in 50

The inequality that represents the amount of money Alex needs to earn is y = 11.50x and 9x + 100.
<h3>How to depict the information?</h3>
The slope and the y intercept of both of the works will be:
For the tech company:
y = 11.50x
m = 11.50
y = 11.50(8 × 20)
y = 11.50(160)
y = 1840
For the amusement park
amusement parky = 9x + 100
amusement parky = 9x + 100y = 9(320) + 100
y = 2880 + 100
y = 2980.
When he wants to make the exact amount, the number of hours will be:
9x + 100 = 2200
9x = 2200 - 100
9x = 2100
x = 233.3

Answer:
an = -39 -100(n -1)
Step-by-step explanation:
The given sequence can be described by a 3rd degree polynomial.* However, we suspect a typo, and that your intention is to have a formula for the arithmetic sequence ...
-39, -139, -239, -339
This has a first term a1 = -39, and a common difference d = -100.
The model for the explicit formula is ...
an = a1 +d(n -1)
Filling in the given values, the formula you seek is ...
an = -39 -100(n -1)
_____
* That polynomial is ...
an = 50n^3 +350n^2 -800n +461
This gives a sequence that starts ...
-39, -139, -139, -339, -1039, -2539, -5139, -9139, ...
