Answer:
C
Step-by-step explanation:
Work the equations out to find your answer to each, then you see the answer
A rational inequality is "an inequality which contains a rational expression." When trying to solve rational inequality's you need to first find the zeros, two find the undefined points then you divide the two in order to get your answer.
Hope this helps!
Yes because 4x3^x =12^x since the coefficient is added to the answer because it is in the 3.

Answer:
-2-2√3, -2+2√3
Step-by-step explanation:
Let x represent one of the numbers. Then the other number is -4-x. We want the product to be -8:
x(-4-x) = -8
-4x -x^2 = -8 . . . . . eliminate parentheses
x^2 +4x = 8 . . . . . . multiply by -1
x^2 +4x +4 = 12 . . . add 4 to complete the square
(x +2)^2 = 12
x +2 = ±√12 = ±2√3
x = -2±2√3
The two numbers are -2-2√3 ≈ -5.4641, and -2+2√3 ≈ 1.4641.
