Answer:
C. 3
Step-by-step explanation:
The constant of proportionality is the slope (or rate of change) of the graph.
To find the equation of the graph;
Take points (1,3) and (3,9)
The slope (m) = change in y ÷ change in x
m = 
Taking another point (x,y) on the graph;
m = 
y - 3 = 3x - 3
y = 3x + 0
y = 3x
This can be expressed as;
y ∝ 3x
Which means that as y rises, x rises too but 3 remains the same. The value 3 is the constant of proportionality in this relationship.
Let the amount that Brandy paid be b, the amount that Katie paid be k, and the amount that Stephanie paid be s.
b=2k
s=k+3
b+s+k=56
Substituting and doing the equation only in terms of k, we get:
2k+(k+3)+k=56
4k+3=56
4k=53
k=13.25
Katie paid $13.25.
Hope this helps!
Answer:
four consecutive integers are
3,4,5,6
Step-by-step explanation:
Let x, x+1, x+2 and x+3 are the four consecutive positive integers
greatest integer is x+3
least integer is x
the greatest integer in the set is twice the least integer

subtract x from both sides

the value of x is 3
x+1 is 4
x+2 is 5
x+3 is 6
so four consecutive integers are
3,4,5,6
