Answer:
A=the outcome is odd, B=the outcome is even
Is mutually exclusive because you can't have a number that is even and odd at the same time.
Hope this helps :)
X+y=-1
3x-y=21
add them equations
x+y=-1
<u>3x-y=21 +</u>
4x+0y=20
4x=20
divide by 4
x=5
x+y=-1
5+y=-1
minus 5 both sides
y=-6
(x,y)
(5,-6)
D is answer
What are you trying to figure out??
Answer:
16.49
Step-by-step explanation:
21^2 - 13^2 = 272
square root 272 = 16.49
At x=0 y=6 the y intercept. The rate is -0.25 so the equation is y=6-0.25x. The ordered pair is (x,6-0.25x).
