Answer:
is the second answer 2x+1/x-1
Answer:
(x + 4)² + (y - 7)² = 20²
Step-by-step explanation:
Graphing form
(x - h)² + (y - k)² = r²
(h, k) is the center = (-4, 7)
r is the radius = 20
-----------------------------------
Plug in the givens
(x + 4)² + (y - 7)² = 20²
We know that : 1 kg = 2.2 pounds.
x = 2.81 * 2.2 = 6.182 pounds
s = 1.32 * 2.2 = 2.904 pounds.
Answer:
The mean increase: x = 6.182 pounds.
The standard deviation: s = 2.904 pounds.
Pretty sure it's x= -2. multiply everything by 3
then combine.
10= 6^x you can work it like a log and minus 10 from each side.
0= -4^x
so what raised to the power gives you -4? x=-2
