Answer:
A proportional relationship can be represented in different ways: a ratio table, a graph of a straight line through the origin, or an equation of the form y = mx, where m is the constant of proportionality
0.884
Step-by-step explanation:
just use a calculator
x=3
The square root of 225 is 15
so 15=4x+3
-3 -3
12=4x
If 12=4x then x=3
Y1=2/3x , Y2=2/3x-2
those are the graph of the functions
