Answer:
x=7
y=2
Step-by-step explanation:
10 + 2x = -2y ➡y = -5-x
replace y with -5-x in the first equation
-5-x-x = 9➡ -2x-5 = 9 ➡-2x = 9+5 ➡ x = -7
now use this information to find value of y
y - (-7)=9 ➡y = 2
Answer:
Step-by-step explanation:
The team draws with a probability of 1 = (0.5 + 0.2) = 0.3
If the team does not win then it loses or draws.
Loosing = 0.2
Draw := 0.3
P(not win) = 0.2 + 0.3 = 0.5
======================
Not lose means wins or draws.
P(not lose) = 0.5 + 0.3 = 0.8
======================
Not Draw means wins or loses
P(not draw) = 0.5 + 0.2 = 0.7
Of course all of these could be done more directly.
P(not win)= (1 - win) = 1- 0.5 = 0.5
P(not lose) = ( 1 - lose) = 1 - 0.2 = 0.8
P(not draw) = (1 - 0.3) = 0.7
A vertical linehas undefined slope because all points on the line have the same x-coordinate.
To make this a fraction, let's put

. We can divide both top and bottom by 6, leaving us with

. This is as far as we can reduce it, making it your answer. I hope this helps!
