Answer:
x=-32/29

Step-by-step explanation:
3x+4y=36 Equation 1
-5x+3y=35 Equation 2
Multiplying equation 1 with 3 (value before y in equation 2) and equation 2 with 4 (value before y in equation 1) we obtain equations 3 and 4 as follows
9x+12=108 equation 3
-20x+12y=140 equation 4
Subtracting equation 3 from equation 4 we obtain
-29x=32
x=-32/29
To find the value of y, we substitute the value of x into equation 2 as initially given in the equation
-5(-32/29)=35-3y
-5(-32/29)-35=-3y

Answer:
f(x)=(x-6)(x-(-7))

Answer:
D. 52
Step-by-step explanation:
Add 85 and 45 to get 130.
6.2n-3.7n=130
Subtract 3.7 from 6.2
2.5n=130
divide 130 by 2.5 to find n
N=52
Answer:
0.014
Step-by-step explanation:
The probability that the Islanders will win at least 6 out of seven is the probability of them winning exactly 6 games, P(X=6), added to the probability of them winning all seven games, P(X=7).
This problem can be treated as a binomial probability model with probability of success p = 0.38 in each of n = 7 games.

Thus:

The probability is:

The probability that the Islanders will win at least six out of seven games in a series against the Rangers is 0.014.
During a research experiment, it was found that the number of bacteria in a culture grew at a rate proportional to its size. At 8:00 AM there were 6,000
