Answer:
B (I think)
Step-by-step explanation:
A function can't have two X values that are the same (If I remember correctly) and the second table is the only one that doesn't have duplicated X values
<span>1/7(x) +27/7
= 1/7 (x + 27)
hope it helps</span>
Step-by-step explanation:
When the denominator is zero, the expression is undefined
2x-4=0
2x=4
x=2
i dont have much time to go through all the work but i can tell you that since its a 90 degree angle, your equation would be 90=15x-2+7x+4. Once you get the value of X plug that into each of the equations. For example if your x value was 2 you would do 15(2)-2. Thats just an example.
