Answer:
Hi there!
The first one is not a function because it crosses twice using the vertical line test while the second one is a function.
Step-by-step explanation:
These equations seem tricky, but aren't as hard as you think. Just solve it like you are regularly adding fractions.
Your common denominator is 9x + 9, so
1/(9x+9) = 36/(9x + 9) - (5x + 5)/9
1 - 36 + 5x + 5 / 9x - 9
30x - 30/9x - 9
10x-10/3x - 3
10(x-1)/3(x-1)
10/3
Hope this helped!
The answer is C. This is because -4 is less than 0, so there can't be any counters if the value is less than 0.
