Answer:
no solution
Step-by-step explanation:
y = -2x + 3
6x + 3y = -3
the substitution method means you plug one equation into the next, because the first equation gives us a solution for y we can go ahead and plug that into y of the second equation
6x + 3(-2x + 3) = -3
6x - 6x + 9 = -3
9 = -3
which is false meaning that there are no solutions and the lines don't touch at any point
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.
Answer:
5 hours, y= how much money it will cost, and x represents how many hours
Step-by-step explanation:
y= 15x+45
120= 15x+45
-45 -45
75= 15x
75/15×= 5 hours
