Answer:
-∞
As x approaches -∞, y=f(x) approaches -∞
Step-by-step explanation:
Given the function;
y = 0.5*6x
We want to determine the limit of y as x tends to minus infinity.
lim x→-∞ f(x) = lim x→-∞ y
y = f(x)
lim x→-∞ f(x) = 0.5*6(-∞)
lim x→-∞ f(x) = 3(-∞)
lim x→-∞ f(x) = -3∞ = -∞
As x tends to -∞, y=f(x) approach -3∞
But, three times minus infinity is still equal to minus infinity.
-3∞ = -∞
Therefore, As x approaches -∞, y=f(x) approach -∞

Answer:
a.
and 
Step-by-step explanation:
Let x be the larger number and y be the smaller number.
We have been given that one number is 4 more than another. We can represent this information in an equation as:

We can manipulate this equation as:


We are also told that the sum of both numbers is 60. We can represent this information in an equation as:

Upon looking at our given choices, we can see that option 'a' is the correct choice.
