Since they only give you the y values in the table, it would be easier if you isolated the x in the rule:
y = x/4
Multiply both sides by 4
4y = x
Now you can simply substitute the y values into the rule to get the x
4(4) = 16
4(2) = 8
4(9) = 36

Answer:
b.
Step-by-step explanation:
In can be less mental effort if the equation is multiplied by -1 first.
.. x^2 -10x +8 = 0
.. x^2 -10x +25 +8 -25 = 0
.. (x -5)^2 = 17
.. x -5 = ±√17
.. x = 5 ±√17
The values of x that satisfy the given equation are
.. x = 5 -√17 ≈ 0.877
.. x = 5 +√17 ≈ 9.123
X should equal 8 because if you add the three numbers they give you. You will get 20 and the whole thing is 28
Answer:
As 
and as 
Step-by-step explanation:
Please look at the plotted points in the attached image. There we see that as x grows toward infinity (to the right), the values for f(x) seem to become more negative (so f(x) seems to go towards minus infinity).
As we move towards the left with values of x (x going towards negative infinity, f(x) seems to become more and more positive (grow toward infinity)
