The circle increase in area will be by a factor of 1.5
So corresponding increase in the diameter will be a factor of sqrt 1.5 = 1.2247

Answer: C
Step-by-step explanation:
Answer:

Step-by-step explanation:
Let
x------> the number of years
we know that

Solve for x




X intercept: when y = 0
y intercept: when x = 0
Plug info inside the equation
3x + 7(0) = 42
3x = 42, x = 14
Therefore, x intercept: (14,0)
3(0) + 7y = 42
7y = 42, y = 6
Therefore, y intercept: (0,6)
