Answer:
40
Step-by-step explanation:
9a + 9b + 9c = 5
We want 72a
72a/9a = 8 so multiply the first equation by 8
8(9a + 9b + 9c) = 5*8
72a +72b +72c = 40
Answer:
I think the answer would be ( 2, 5 )
Step-by-step explanation:
The formula for rotating a shape 270 degrees counter clockwise is ( y, -x ) meaning that the original coordinates of B ( -5, 2 ) will become ( 2, 5 ). The 5 is positive because the negatives cancel out. :)
Answer: a
explanation: the vertical line test tests if the line is a function by stating that if it intersects the graph more than once it is not a function. if you drew a straight line through this line it would touch the graphed line twice, meaning it’s not a function.
Answer:
Step-by-step explanation:
<span>Answer: Given an > 0 we need an N such that n, m > N means |sn â’ sm| < . We are free
to assume that n > m (since they otherwise play symmetric roles in the definition of a Cauchy sequence).
Then
sn â’ sm = (â’1)mam+1 + . . . + (â’1)nâ’1
an = (â’1)m</span>
