<h3>Answer:</h3>
The Second one {(-8,-7), (4,-2), (2,9), (-8,8)}
<h3 /><h3>
Step-by-step explanation:</h3>
A function only gives ONE out put for a given value. But the second set has two outputs if we input -8, it gives you -7 and 8 so this must not be a function.
5-1 x 20=56/56 x 90/56 54/67=67
Answer:
Step-by-step explanation:
A proportion could be used.
With 2 parts of compost and 6 parts potting soil, you would end up with 8 total parts.
So it can be written as a ratio of compost to total mix, or 
The problem states 10 kg are needed in total, and the variable would be the amount of compost
As a ratio it would be 
.
Use the ratios to write a proportion.
Multiply both sides of the equation by 10
Convert to a decimal if desired.
Answer:
[see below]
Step-by-step explanation:
A function's inputs do not repeat. This means that any point with the x-value not repeated with the other points can be added to ensure that it continues as a function.
In this scenario:
{x| x ≠ -7, 4, 0, -2}
A point that does not have the x-value of -7, 0, 4, and -2 could be added to the relation to ensure it continues to be a function.
Hope this helps.
