Answer:
Step-by-step explanation:
-3a + 6b = a + 4b
-4a + 6b = 4b
-4a = -2b
a = -2b/-4
f(a) = -b/2
Answer:
Clearly, the probability of drawing a heart out of the deck is 13/52, or 1/4. The probability of drawing an even number as card #2 (∈{2,4,6,8,10}) for any suit is 20/51, except when the first card drawn is an even heart, then the probability of the second draw is 19/51.
The answer to the question is the second and the fourth equations
No factors are for multiplication and divisors are for division i think
