Answer: y = x - 5
<u>Step-by-step explanation:</u>
"Eliminate the parameter" means we want to eliminate the <em>extra </em>variable and rewrite it ias one equation that only contains x, y, <em>and possibly a constant.</em>
<em />
The extra variable in the equations is "t". Manipulate one of the equations to solve for t². Then substitute t² = _____ it into the other equation.
x = t² + 3 → x - 3 = t²
y = t² - 2
y = (x - 3) - 2
y = x - 5
Option C: 
is the predicted population when 
Explanation:
The regression equation for an exponential data is 
Where x is the number of years and
y is the population
We need to determine the predicted population when
The population x can be determined by substituting in the equation
Thus, we have,
Using the logarithmic definition 
then 
Rounding off to the nearest whole number, we get,
Thus, the predicted population when is 316
Hence, Option C is the correct answer.
Answer:
x=31/25
Step-by-step explanation:
3x+4/5=7-2x
Multiply through by 5
5(3x+4/5)=5(7-2x)
15x+4=35-10x
Collecting like terms
15x+10x=35-4
25x=31
x=31/25
