Answer:
3rd option,, then the 4th option,, then the 1st option
Step-by-step explanation:
(3,4,5)
Using 1 you get, 7>12
Using 2 you get, 12>12
Using 3 you get, 17>12
Using 4 you get, 20>12
Using 5 you get, 27>12
this is why only 3,4, and 5 work.
Answer:
y = √(x) + 4
Step-by-step explanation:
Note that the basic function and graph here are of y = √x. The graph of this basic (parent) function has the same shape as the graph shown, EXCEPT that the graph of y = √x has been translated 4 units upward.
Now look at the given graph. We want to find the function represented by this graph. We note that the shape of the graph is exactly the same as that of the graph of y = √x, except that the latter graph has been shifted up 4 units.
Thus, the parent function y = √x becomes y = √(x) + 4.
So, if the father is 60, his son is half his age, which would be 30.
So, to find out how old the boy was when his father was 4 times his age, you would do, 30 divided by 4 (I believe).
You then should get, 7 1/2 years old the boy is.
Hope this helps! Have a great rest of your day! c:
