Answer to Problem 8E
No.
Explanation of Solution
Given information:
The linear equations are:
Calculation:
The linear equations are:
To find whether each ordered triple is a solution of the system of equations or not, plug the ordered triple
Both sides are not equivalent. It mean the ordered triple are not satisfies the system of equation. Therefore, the ordered triple
b.
The solution of the system of equations.
b.

Answer to Problem 8E
Yes.
Explanation of Solution
Given information:
The linear equations are:
Calculation:
The linear equations are:
To find whether each ordered triple is a solution of the system of equations or not, plug the ordered triple
Plug the same ordered triple
Plug the same ordered triple
The ordered triple fits all the three equations so, all the three system of equations are equivalent.
Thus, it is a solution to the system of equations.
c.
The solution of the system of equations.

Precalculus with Limits
- 3. We'd like to know the first time when the population reaches 7000 people. First, graph the function from part (a) on your calculator or Desmos. In the same window, graph the line y = 7000. Notice that you will need to adjust your window so that you can see values as big as 7000! Investigate the intersection of the two graphs. (This video shows you how to find the intersection on your calculator, or in Desmos just hover the cursor over the point.) At what value t> 0 does the line intersect with your exponential function? Round your answer to two decimal places. (You don't need to show work for this part.)

Find an exponential function f(t) that gives the population of Tattooine t years from now. (3 points)arrow_forwardA house was valued at $95,000 in the year 1988. The value appreciated to $170,000 by the year 2007. A) If the value is growing exponentially, what was the annual growth rate between 1988 and 2007? Round the growth rate to 4 decimal places. r = B) What is the correct answer to part A written in percentage form? r = 3 %.arrow_forward
