Let's simplify step-by-step.
x−5x+4+8x−71
=x+−5x+4+8x+−71
Combine Like Terms:
=x+−5x+4+8x+−71
=(x+−5x+8x)+(4+−71)
=4x+−67
Answer:
=4x−67
Answer: b
Step-by-step explanation:
You can determine which is a function by looking at the x values. If an x value repeats, it is not a function. In A, the x variable 2 repeats so it is not a function. In C, the x variable 5 repeats. In D, the x variable -5 repeats. The only answer choice where none of the x values are the same is B, so the answer is B. Hope this helps!
They are both equal because in decimals you can add thousands of zeros and it's still equal.
