Answer:
6x + 35
Step-by-step explanation:
First Distribute
8x + 3x + 15 -5x +20
Then collect like terms
6x + 35
to solve you would need the value of x to plug it!
6.75 X 10 to the tenth power
domain of the problem is -5 and the range is 4
All it takes for a relation to be a function is for each possible first number of a pair there's only one possible second number.
So if any of the sets has two pairs with the same first number, that one's not a function.
The last one has (3,2) and (3,5) so isn't a function.
