Answer:
Step-by-step explanation:
- -13x < 65
- x > - 65/13
- x > -5
- x = (-5, + oo)
The Sum of this question is.... -43.
-25 - 18 equals to -43.
The correct answer is B) the cost of removing 80% of pollutants is $196,000.
Using the equation, we have
240(80)/(100-80) = 240(80)/20 = 196
Since this is in thousands of dollars, we have 196,000.
Using the equation, A is not correct; it would be 160,000.
The vertical asymptote would be at 100%.
B must be the correct answer.
f(x)=x²-1
g(x)=2x-3
f(x)*g(x)=(x²-1)*(2x-3)-----------> <span>this function exists for all real numbers</span>
the answer is the interval (-∞,∞)
