Answer:
it is C! if I were to write t<6 on a number line it would be open circle above 6 and going to the left since it is smaller than 6!
Answer:
Rate of change or slope = 
Step-by-step explanation:
It is common that most lines that are graphed are in slope intercept form.
y=mx+b
M represents the slope.
In the question you're asking M = 1/3
Quarter is $0.25
Dollar is just $1
x is amount of quarters
y is amount of dollar coins
Two equations we know
0.25x+1y=10.75 and
x+y=22
solve both for y
0.25x+1y=10.75
y=10.75-0.25x
x+y=22
y=22-x
set them equal
22-x= (y) =10.75-0.25x
11.25=0.75x
x=15 quarters
then put x=15 into either equation and now solve for y
x+y=22
15+y=22
y=7 dollar coins
