Rational root theorem is used to determine the possible roots of a function.
The potential roots are: -3 and 3/2
The function is given as:
For a function,
The potential roots are:
So, we have:
---- factors of 3
---- factors of 6
The potential roots are:
From the options, the potential roots are:

Answer:
-3 and 3/2
Step-by-step explanation:
6x^3 - 2x^2 + x + 3
possible roots are p/q where p = factors of 3 and q are factors of 6
So from the 4 choices possible roots are -3 and 3/2
There are 5 large dogs and 3 small dogs
Let "S" be the number of small dogs
Let "L" be the number of large dogs
Given that There are a total of 8 small and large dogs
So we can frame a equation as:
number of small dogs + number of large dogs = 8
S + L = 8 ------- eqn 1
You realize there are 2 more large dogs than small dogs
Number of large dogs = 2 + number of small dogs
L = 2 + S -------- eqn 2
Let us solve eqn 1 and eqn 2 to find values of "L" and "S"
Substitute eqn 2 in eqn 1
S + 2 + S = 8
2S + 2 = 8
2S = 6
Substitute S = 3 in eqn 2
L = 2 + 3 = 5
Thus there are 5 large dogs and 3 small dogs
Answer:
5 large dogs and 3 small dogs
Step-by-step explanation:
Answer:
15/2, 13/2.
Step-by-step explanation:
Here's a graph as well.
Answer in fraction form = (15/2, 13/2)
Answer in decimal form = (7.5, 6.5)
========================================================
Explanation:
To get the midpoint, we average the two endpoint values. We handle the x and y coordinates separately.
The x coordinates of each point are 6 and 9. They average to (6+9)/2 = 15/2 = 7.5; so you add up the x coordinates and divide by 2.
The y coordinates are handled the same way. Add them to get 4+9 = 13 and then divide by 2 to get 13/2 = 6.5
The midpoint is (15/2, 13/2) = (7.5, 6.5)
