2x -4y= 28
⇒ -4y= 28 -2x
⇒ y= (28 -2x)/ (-4)
⇒ y= 28/(-4) -(2x)/ (-4)
⇒ y= -7 + 1/2x
The final answer is y= -7 + 1/2x~
Answer: ![\approx8*10^{-3}](https://tex.z-dn.net/?f=%5Capprox8%2A10%5E%7B-3%7D)
Step-by-step explanation:
In order to round to the nearest thousandth, you must observe the digit to the right of the digit in the thousandth place and then:
- If it is less than 5, you must round down.
- If it is greater than or equal than 5, you must round up.
In this case, given the number:
![0.00792398](https://tex.z-dn.net/?f=0.00792398)
You can notice that the digit to the right of the digit in the thousandth place is 9.
Since
, you must round up. Then:
![0.00792398\approx0.008](https://tex.z-dn.net/?f=0.00792398%5Capprox0.008)
Finally, to express this as a single-digit times a power of ten, move the decimal point three places to the right. Then you get:
![\approx8*10^{-3}](https://tex.z-dn.net/?f=%5Capprox8%2A10%5E%7B-3%7D)
