Step-by-step explanation:
these are the functions
and the others are not a functions because the domain can't match to more than one
Answer:
8x-y+4=0
Step-by-step explanation:
because 8x-y+4=-4+4
Answer:
- <em><u>1. There are infinite 8's</u></em>
- <em><u>2. The estimate is 130.89</u></em>
- <em><u>3. The difference is 0.01</u></em>
<em><u /></em>
Explanation:
There are countless, or infinite, 8's in the answer because the result is a periodic decimal:

The notation used for the periodic decimal numbers is an arc over the number that is repeated. In this case, it would be an arc over the first 8.
I will use a bar just to show how it is, but instead of a bar it should be an arc:

The <em>estimation</em> or approximation to <em>two decimal places</em> requires to drop the 8's since the third one and increase the second 8 to 9 (because the first decimal dropped is greater than or equal to 5).
Thus the estimated value would be 13.89.
The difference is:
- 130.89 - 130.888. . . = 0.0111. . .
- Rounded to 2 decimal places: 0.01

I googled it
<span>If 4 cans of coffee cost 2.40, then divide this by 4 to find out how much one can of coffe costs: 2.40/4 = .60. Now, we need to find 1/4 of .60. To do so, again divide by 4: .60/4 = .15. So, the cost of 1/4 can of coffee will be 15 cents.</span>
