Answer:
Multiply both sides by -2 and reverse the inequality symbol
Step-by-step explanation:
since it is division you want to make it multiplication so that you can get the answer easier
-1/2w<12
it cancels out the -1/2 than just multiply 12 and -2 you get -24
w > -24
F(5) = -2 * 5 + 1 = -9
the pair is (5, -9)
Answer:
6) B distributive property 7) B distributive property 8) C associative property
Step-by-step explanation:
You have several possible points
. Any point that lies on the given line will have a
value that you obtain by plugging in the corresponding value of
into the equation of the line.
The line has equation
, so any point on the line will have the form
.
Among the four given points, there are only 2 different values of
to check. We have


which means the given line contains the points (4, -5) and (1, 4). So the answer is A.
Imagine, at the first day you have only one penny. Then tomorrow you have 2 pennies, next day you have 4 (2x2), next day you have 8 (4x2), next day you have 16 (8x2).... and so forth.
It looks like geometric sequence isn't it? (the ratio between the number of pennies that you have from the 2nd day and the 1st day is 2)
So, by using geometric sequence theorem we can total those pennies until day-27
S (total pennies at day-27) = (1)(2^27-1) / 2-1 = 2^26 pennies
So, you have 2^26 pennies.. a big number of pennies huh?=))
{The formula is: S = a( r^n-1) / r-1
Where:
a= the number of pennies that you've got at the 1st day
n= number of days you spent to collect those pennies)
r= the ratio of the number of pennies}
