Answer:
(x+1) is a factor with remainder 0.
Step-by-step explanation:
We divide (x+1) into the polynomial 
through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial .
We subtract this from the original 
.
This leaves 
. We repeat the step above.
.
We subtract this from 
. We repeat the step above.
.
We subtract this from 
. We repeat the step above.
.
We subtract this from 
. There is no remainder. This means (x+1) is a factor.
ANSWER
EXPLANATION
The given exponentiial expression is
We simplify using the rule:
We apply this property to get:
We simplify to get;
We rewrite as a positive index to get;
D the point of intersection is the solution
1-7/3-1
-6/2
-3
Therefore, the slope of the line that passes through these points is -3.
A complementary angle would be 90-x. in this case, x is 48°, so set up the equation 90-48 = other angle. this would give you 42, so the answer is A.
