Answer:
<em>x = -8; y = 0</em>
Step-by-step explanation:
x + 2y = -8
3x - 4y = -24
We will use the substitution method.
Solve the first equation for x.
x = -8 - 2y
Replace x of the second equation with <em>-8 - 2y</em>, and solve for y.
3<em>x</em> - 4y = -24
3<em>(-8 - 2y)</em> - 4y = -24
-24 - 6y - 4y = -24
-24 - 10y = -24
-10y = 0
y = 0
Now we substitute 0 for y in the first original equation and solve for x.
x + 2y = -8
x + 2(0) = -8
x + 0 = -8
x = -8
Solution: x = -8; y = 0

Answer:
P(A)=0.55
P(A and B)=P(A∩B)=0.1265
P(A or B)=P(A∪B)=0.7635
P(A|B)=0.3721
Step-by-step explanation:
P(A')=0.45
P(A)=1-0.45=0.55
P(B∩A)=?
P(B|A)=0.23
P(B|A)=(P(A∩B))/P(A)
0.23=(P(A∩B))/0.55
P(A∩B)=0.23×0.55=0.1265
P(A∪B)=P(A)+P(B)-P(A∩B)
=0.55+0.34-0.1265
=0.7635
P(A|B)=[P(A∩B)]/P(B)=0.1265/0.34 ≈0.3721
I don't know but its at the tip of my tounge
A is the first value of the sequence, then you increase or decrease by d each time
