Answer:
4/27
Step-by-step explanation:
You just add 4/9 + 1/3 = 4/27 and I believe there is no way to simplify.
Your y-intercept would be (0,-15) and your x-intercept would be (-60,0)
Answer:
18%
Step-by-step explanation:
Since the original price is $78 then this is the original 100% of the price. The new price will be marked up x percent and be $92. To find the new price set up a proportion with these values:

Solve for the original price by cross multiplying numerator with denominator.
x(78) = 92(100)
78x = 9200
x= 117.9 = 118%
This is 18% more or over the original price.
the zero(s) of function
is x=2
Step-by-step explanation:
We need to find the zero(s) of function algebraically.
We are given: 
To find the zeros we put the function equal to zero.

So, the zero(s) of function
is x=2
