After trial and error, you discover that - 2 works.
-2 || 3 16 18 -4

====================================
3 10 - 2 0
What you have left is a quadratic
3x^2 + 10x - 2 You can just use the quadratic formula to solve for the other 2 roots.
x1 = [ - 10 +/- sqrt(10^2 - 4*3*(-2) ) ] / 6
x1 = [ -10 +/- sqrt (100 + 24) ) /6
x1 = [ - 10 +/- sqrt(124) ) / 6
x1 = [ - 10 +/- 11.14 ] / 6 = 0.1893
x2 = [ - 21.14 ] / 6 = - 3.522
Answer
x1 = - 2
x2 = 0.1893
x3 = - 3.522
A Horizontal line means you get a slope of zero

Answer:

Step-by-step explanation:
Given:
Number of bushes planted = 5
Minimum number of bushes to be planted = 12
Let the number of bushes planted after planting 5 bushes be
.
Since, Tamara has already planted 5 bushes, total number of bushes planted is given as:

Now, as per question, total number of bushes should be 12 or greater than 12.
Therefore,
.
Answer:
Kennan will be from home approximately an hour and 48 minutes.
Step-by-step explanation:
We must know that total time (
) that Keenan will be from home is the sum of run (
), hang out (
) and walk times (
), measured in hours:

If Keenan runs and walks at constant speed, then equation above can be expanded:

Where:
,
- Run and walk distances, measured in miles.
,
- Run and walk speeds, measured in miles per hour.
Given that
,
,
and
, the total time is:

(
)
Kennan will be from home approximately an hour and 48 minutes.
