The expression ...
... (x+1)/(x²+2x-24)
will have a zero denominator when
... x² +2x -24 = 0
... (x +6)(x -4) = 0 . . . . . factored form
... x = -6, x = 4 . . . . . . . values of x that make the factors zero
The rational expression will be undefined when x = -6 or x = 4.
Answer:
C) The solution for the system of equations
Step-by-step explanation:
Point (3, 120) is where both lines intercept!
Basically, (3, 120) is where both equations are equal to each other.
(120 = 20(3) + 60) = (120 = 40(3))
We can test it!
120 = 20(3) + 60
120 = 60 + 60
120 (Correct)
120 = 40(3)
120 = 120 (Correct)
Answer:
Below.
Step-by-step explanation:
0.04x20 =0.8 or 80 percent.
80 percent of six thousand is 4800+6000 = 10,800
2 1/7 is a mixed number BUT it is also a rational number.
Turning this into a improper fraction, you'd get 15/7
15/7 = 2.14285...
Repeating decimals are rational numbers
