The linear function that represents this graph is given by:
y = 300 - 0.6667x.
A linear function is modeled by:
y = mx + b
In which:
From the graph, when x = 0, y = 300, hence the y-intercept is of b = 300. The amount decays to 0 when the x-intercept is of x = 450, hence the slope is given by:
m = -300/450 = -0.6667.
Which means that the equation is:
y = 300 - 0.6667x.

Answer:
1) 3<x≤15
2) w>-3
3) t>2 and t<-6
4) q<-15 and q≥-3
5) -6<p<5
Step-by-step explanation:
I will solve one problem to show you.
1) -2<x-5≤10
add 5 on both sides
-2+5<x-5+5≤10+5
3<x<15
