Answer:
Step-by-step explanation:
6y - y = y(6 - 1) = y * 5
The answer is 5y.
The answer is D) 0.0000000692
<em>Explanation:
</em>Since the equation is
6.92 * 10^ -8
You know that you need to move the decimal 8 places to the left ( left is negative, right is positive)
If you move the decimal 8 places to the left the decimal still needs to pass the 6, so there will actually be 7 zeroes instead of 8.
Let us check series : -10 /-2 = 5 -50/-10 = 5
so it is a geometric series with a= -2 and r= 5
sum formula for n terms of geometric series = a ( r^n -1 ) /( r-1)
here we find S5 that is n= 5 = -2 ( 5^ 5 - 1) /( 5-1)
= -2 ( 3125 -1) / 4 = -1562
second series is : 1.5/1 = 1.5 2.25/1.5 = 1.5
this is also geometric series but n = 12 a= 1 and r= 1.5
we use same formula
S12 = 1 ( (1.5) ^12 -1) /( 1.5-1) =
128.74 / 0.5 = 257.49
Last is 2/1= 2 4/2 = 2 8/4 = 2 so r = 2 a = 1 and n = 12
we use same formula 1 ( 2^12 - 1) / (2-1)
= 4095

Answer:
1. y > −2 AND y < 2
Step-by-step explanation:
6 − 5y > −4 AND 7y + 20 > 6
-6 - 6 - 20 - 20
_________ _________
−5y > −10 AND 7y > −14
y < 2 AND y > −2
