Answer:
It would be difficult to factor it...
Step-by-step explanation:
I'm not sure factoring would work so the quadratic formula would be the only way
Answer:

Step-by-step explanation:
Given
The above table
Required
Determine the probability of a sum that is a multiple of 6
Represent the event that an outcome is a multiple of 6 with M.
List out all possible values of M

Number of M is

Total possible outcome is:

The theoretical probability is then calculated as follows:

In this case, it is:


Simplify fraction

-21 is your answer
it is reflected over the x axis, and the point is on 21 no?
F(x) = -5x + 3
f(-4) = -5(-4) + 3
f(-4) = 20 + 3
f(-4) = 23
