Answer:
For anyone needing to know:
Step-by-step explanation:
The line is horizontal the slope is 0
y = -2x - 9 ----------- 1
y = 3x + 1 -------------- 2
Step 1
Substitute y from equation 1 to equation 2.
y = -2x - 9
3x + 1 = -2x - 9
Step 2
Collect like terms
3x + 2x = - 9 - 1
5x = -10
Step 3
Divide through by 5
x = -10/5
x = -2
Step 4
Substitute x in equation 2 to find y.
y = 3x + 1
y = 3(-2) + 1
y = -6 + 1
y = -5
So the solution is (-2, -5)

Answer:
P ( Black then Red ) = 0.24725
Step-by-step explanation:
Given:-
- Red Checkers = 5
- Black Checkers = 9
Find:-
A checker is selected, kept out of the bag, and then another checker is selected. What is P(black, then red)?
Solution:-
- We will utilize the fundamental counting principle. A bag contains a total of ( 5 + 9 ) = 14 checkers in total.
- We will draw two checkers one at a time without replacement.
First Draw: Black = 9 possible outcomes
P ( Black ) = 9 / 14
Second Draw: Red = 5 possible outcomes
P ( Red ) = 5 / 13
- The required probability P(black, then red) for dependent events is given as:
P ( Black then Red ) = P (Black first draw) * P ( Red second draw)
= ( 9 / 14 ) * ( 5 / 13 )
= 0.24725
