The negative sign in front of the 5 means that you inverse it,
i.e. n^-5 = 1/n^5
(one over n to the power of 5)
Answer:
Step-by-step explanation:
You have no grounds for making a statement like that. There are a variety of reasons why you might not get immediate answers. Be patient.
I will do the second part of this question (finding the first three numbers):
a(4) = a(3)*(-3) + 2 = -148, so a(3)*(-3) = -150 and a(3) = -50
a(3) = 50
a(2) = a(3)*(-3) + 2 = 50, so -3*a(3) = 48 and a(d) = -16
a(1) = a(2)*(-3) + 2 = -16, so a(2)*(-3) = -18 and a(1) = 6
The procedure for finding a(5), a(6) and a(7) is exactly the same.
For this you will need to calculate the number of sweaters - 7x. Then you need to calculate the number of shirts - 9y. Last you need to calculate the number of pants - 12z. To balance the equation, you must calculate the total price $172+$269+$74 = $515. The equation is 7x+9y+12z = $515.
It should be D, if -7x-2 is 14, then -5x-2 will be 10.
Answer:
Step-by-step explanation:
Let's break it down. There is..
-----------------------------------------------------
A square root of a number: 
(assuming "the number" is 
).
And they say that 9 is less than that, so we subtract 9 from , which gives us .
I hope that helps! :)
