Ok, basically if you want to find when both equations are equal just make them equal to each other. 0.925x^2 - 4x + 20 = -1.125x^2 + 6x + 40.
From there use algebraic steps to find out what x is ( the break - even point ).
0.925x^2 - 4x + 20 = -1.125x^2 + 6x + 40
0.855625x - 4x + 20 = 1.265625x + 6x + 40
-0.41x - 4x + 20 = 6x + 40
-4.41x + 20 = 6x + 40
20 = 10.41x + 40
-20 = 10.41x
-1.92122958694 = x
Rounded to the nearest tenth it's -1.9 = x.
Tell me if I got something wrong :)
Answer:
x=24.583
Step-by-step explanation:
first, find a common multiple of both 50 and 6. I used 150, I turned 2.95 into 73.75. so 73.75/150 reduced into '50s would be 24.583. or you can just say 2.95/6= 24.58/50. you can also use an online calculator if you believe that this is incorrect

So what's your Question.
I think The Mean ????
Step-by-step explanation:
So it is Add all the Values which is 103
Divide it by no. of Values which is 8
You'll get 12
Which is Mean !!!!
If you would like to know the average rate in miles per hour, you can calculate this using the following steps:
420 miles ... 210 minutes
x miles = ? ... 1 hour = 60 minutes
420 * 60 = 210 * x
x = 420 * 60 / 210
x = 120 miles
The correct result would be 120 miles per hour.
