Each new term of this arith. seq. is obtained by adding 4 to the previous term. Hence, 15 = 11+4; 19=15+4, and so on. Add 4 to 19 to get the next term. Keep going until you have 4 new terms for the arith. seq. 11, 15, 19, .....
(x)(3x - 5) = 12
3x^2 - 5x = 12
3x^2 - 5x - 12 = 0
(x - 3)(3x + 4) = 0
x = 3, -4/3
The answer must be negative so the number is -4/3.
Hope this helps!
The Olmecs (/ˈɒlmɛks, ˈoʊl-/) were the earliest known major civilization in Mesoamerica following a progressive development in Soconusco. They lived in the tropical lowlands of south-central Mexico, in the present-day states of Veracruz and Tabasco. It has been speculated that the Olmecs derive in part from neighboring Mokaya or Mixe–Zoque.

Answer:
(a) and (f)
Step-by-step explanation:
Given

See attachment for table and options
First, we calculate the slope of the table

Using:


So, we have:



The equation is then calculated using:

This gives:



So, we have:
--- The given equation
and
--- The equation of the table
An equation is represented as:

Where:
m = slope or rate of change
b = y intercept
So, for the given equation: 
Rate of change = 5
y intercept = 12
For the table: 
Rate of change = 12
y intercept = 5
In conclusion:
(a)
has the greater rate of change:
and
(f)
has the greater y intercept
