Answer:
14%
Step-by-step explanation:
A = P(1 +rt) . . . . . . . . . . . . . . . . . . formula for the balance for simple interest
2848.52 = 2006(1 +3r) . . . . . . . filling in the given numbers
1.42 = 1 +3r . . . . . . . . . . . . . . . . . .divide by 2006
0.42 = 3r . . . . . . . . . . subtract 1
0.14 = r = 14%

Answer:
Slope= -5
Step-by-step explanation:
The formula for slope= (y2-y1)/(x2-x1)
First you label your points:
X1=-9
Y1=6
X2=-6
Y2=-9
Next you plug in your points and solve
-6-9=-15
-6-(-9)=3
And finally, you simplify
Slope= -15/3=5

The domain of a function is the set of values of x for which a value of y exists. In this case, the only way that a value of y would not exist is for a denominator to equal to zero. If this function is f(x) = 1/(x+1) + 5, then we must find the values of x for which the denominator (x+1) = 0, which is at x = -1.
Therefore the domain is all real numbers except x = -1. In interval notation this can be written as (-infinity, -1), (-1, infinity).
