Answer:
x = 5 and y = 1 or (5, 1)
Step-by-step explanation:
2x -3y=7
3x-2y=13
Multiply (1st) equation by 3 and (2nd) equation by 2
6x -9y=21
6x-4y=26
----------------subtract
-5y = - 5
y = 1
Substitute y = 1 into 2x -3y=7
2x -3(1)=7
2x - 3 = 7
2x = 10
x = 5
Answer
x = 5 and y = 1 or (5, 1)

Answer: 15 cm to the highest total ; amount of triangles: 25
Step-by-step explanation: for the height just add 3 cm until you reach the top, which will give you 15 cm
for the amount just count them and for the top top layer count up to 9, which will give you 25 triangles.
P(B|A) (option B)
Doesn't affect (option A)
P(B|A) = P(B) (option A)
Explanation:
1) Conditional probabilities could be in the form P(A|B) or P(B|A)
P(B|A) is a notation that reads the probability of event B given that event A has occurred.
P(B|A) (option B)
2) Independent events do not affect the outcome of each other
For event A and B to be independent, the probability of event A occurring doesn't affect the the probability of event B occurring
Doesn't affect (option A)
3) Events A and B are independent if the following are satisfied:
P(A|B) = P(A)
P(B|A) = P(B)
The ones that appeared in the option is P(B|A) = P(B) (option A)
Answer:
y-5=11
y-5+5=11+5 (Add 5 to both sides)
y=16 (Simplify)
I believe that y=16 cannot be simplified so y=16 should be the answer let me know if it helped.
