The answer to the equation 3x-5y=21, 2x+y=1 is (2, -3)
Answer:
Step-by-step explanation:
1. The probability that your mail is delivered before 2 pm is 0.9, so the probability that the mail is delivered at 2 pm or after 2 pm (so not before 2 pm) is 1-0.9=0.1.
Remark: 0.9=9/10=90/100=90%, and 0.1 is 10%
2. Probability of the mail being delivered before 2 pm for 2 consecutive days is
3. take a look at the picture attached, the tree diagram is another method we could use.
Using implicit differentiation, it is found that y is changing at a rate of 10 units per second.
---------------------
The equation is:
Applying implicit differentiation in function of t, we have that:
- x-values changing at a rate of 2 units per second means that
- Point Q(1,4) means that
.
We want to find 
, thus:
y is changing at a rate of 10 units per second.

Answer:
the sum of the first 6 terms =189
Step-by-step explanation:
the first 6 terms-
96,48,24,12,6,3
I found them easily by dividing 48 with random small numbers until I got 6 for the fifth term. So here I divided 48 by 2 which is = 24(3rd term), then divided 24 by 2 which is =12(4th term) and then again decide the answer by 2 and finally got 6 for the 5th term. So the ratio is 1/2. For the first term I did the opposite, multiply 48 by 2 which is = 96. And lastly find the sixth term and add them up which is = 189
I tried my best to explain it in simple terms, hope this helps:)
