P = 2m + 2w solve for m
nirvana33 [79]
P = 2m + 2w

Add -2w on both sides of the equations

2m = p - 2w

Divide both sides by 2

2w = p      =      2m
 / 2                      /2

m = 1 / 2 p - w

PLEASE HELP!!!!!!!!<br> What is the 8th term of this sequence? 1,-1/2,1/4,-1/8
Tom [10]
This is a geometric sequence with first term 1 and common ratio -1/2.  r=-1/2.

a(n) = a(1)*(r)^(n-1). 

Check:  If n=2 our formula must return -1/2.  Does it?

a(2) =    1(-1/2)^(2-1)  =  (-1/2)^1 = - 1/2.  Yes.
a(3) should be 1/4.  Is it?     a(3) = (-1/2)^(3-1) = 1/4    Yes. 

Then a(8) = (-1/2)^(8-1) = (-1/2)^7 = -1 / 2^7  = -1/128 (answer)

Which is the graph of y = sqrt x-3
Greeley [361]
<h3>Answer: Choice B</h3>

The parent function y = sqrt(x) has the point (0,0) on it. When we subtract 3, we get y = sqrt(x)-3 which moves the point (0,0) three units down to get to (0,-3)

So (0,-3) is one point on y = sqrt(x)-3
