Answer:
Given function is decreasing for all x-values , except 4.
Step-by-step explanation:
We are given with a graph of the function and we are asked to find x-values for which function is decreasing.
We will say a function is decreasing If as x increases(from left to right) y decreases(goes down).
The given graph has 2 regions till x=4 and after x=4
Till x=4, if we see the graph from left to right, graph is going down, which means it is decreasing.
After x=4 also, as x goes from left to right, graph is going down, which means it is decreasing after x=4 also.
Hence the given function is decreasing for all x-values except x=4.

Answer:
29
Step-by-step explanation:
Let c, r, g stand for the current ages of Carolina, Raul, and Ginny. Then we have the relations ...
c = 2r
g = 3r +4
c + r + g = 52
Substituting for c and g, we get ...
2r + r + (3r +4) = 52
6r = 48 . . . . . . . . . . . . . subtract 4
r = 8 . . . . . . . . . . . . . . . divide by 8
g = 3(8) +4 = 28 . . . . . .Ginny is presently 28
On Ginny's next birthday, she will be 29.
