<h3>How to analyze the table of values?</h3>
The table of values is given as:
x 0 1 2 3 4
y 4 2 1 1/2 1/4
The above table shows an exponential model
An exponential model is represented as:

When x = 0 and y = 4, we have

Evaluate
a = 4
When x = 1 and y = 2, we have

Evaluate

Substitute 4 for a
4b = 2
Divide both sides by 4
b = 1/2
Substitute 4 for a and 1/2 for b in 

Hence, the equation of the table is

Answer:
where is question ???
Step-by-step explanation:
Answer:
3(4+n) = 12+n is an equation that could be used.
12n = 12+n
11n = 12
n= 1+1/11
Step-by-step explanation:
Answer:
35 grams
Step-by-step explanation:
The ratio of zinc to copper is 3 to 11
A jar of chemical contains 385 grams if copper
Therefore the number of grams of zinc it contains can be calculated as follows
3/11= x/385
11x= 385
x= 385/11
= 35 grams
Hence the chemical contains 35 grams of zinc
