The answer is D. "x=-15 or 15."
You can solve this by adding seven on both sides.
|x|-7=8
+7 +7
------------
|x|=15
Therefore, x is either equal to 15 or -15.
-1/7 is the correct answer for slope
Answer:
a(n) = 
Step-by-step explanation:
The given expression is in the form of the explicit formula of a geometric sequence.
f(n) = 
Where 'a' = First term of the sequence
r = common ratio
Recursive formula of a geometric sequence is,
a(n) = 
a(n) =
Where,
So the recursive formula will be a(n) =
Answer:
Axis of symmetry is x = -4
Step-by-step explanation:
h(x)= 5x^2+40x+ 64
Use the formula for axis of symmetry: x = -b/(2a)
Here, a = 5, b = 40, c = 64
so
x = -40/(2*5) = -40/10 = -4
Axis of symmetry is x = -4

This depends on what equipment you have, as I said before the internet is one way but you could use a scale map etc..
