5x + 25y = 60....multiply by -3
3x + 15y = 42....multiply by 5
-------------------
-15x - 75y = - 180 (result of multiplying by -3)
15x + 75y = 210 (result of multiplying by 5)
-------------------add
0 = 30...incorrect.....this system has no solutions

Answer: Option C
Step-by-step explanation:
The graph shows a radical function of the form 
Where n is a positive number.
For this type of function, if the coefficient then then when x tends to 
f(x) tends to and when x tends to 
then f(x) tends to .
Notice in the graph that as x increases then f(x) also increases and as x decreases f(x) also decreases.
This indicates that the coefficient
