The answer to the question would be 6
The domain is the lowest and highest x value. Therefore you must find the end value which you can do by multiplying the difference in the sequence by the number to get 6x31=186. Since you already have the first row you add 186 to that and get 254. So your domain is [68,254], and it represents the total seats in the concert hall.
Answer:
30%: 35 liters
50%: 35 liters
Step-by-step explanation:
The desired concentration is halfway between the concentrations of available solutions, so the mixture will be equal amounts of each.
35 liters of 30% acid and 35 liters of 50% acid must be used
_____
If you want to write an equation, it usually works well to let the variable represent the amount of the most concentrated constituent: 50% acid. Then the amount of acid in the final mix is ...
0.50x +0.30(70 -x) = 0.40(70)
0.20x +21 = 28 . . . . simplify
0.20x = 7 . . . . . . . . . subtract 21; next, divide by 0.20
x = 35 . . . . . . amount of 50% solution (liters)
70-x = 35 . . . amount of 30% solution (liters)
Answer:
Your answer will be C. y= 4x-1
Step-by-step explanation:
On the x value side, the numbers represent what to fill in x with, and y should be the output of it.
For example :
4(1) = 4 - 1 = 3
4(2) = 8 - 1 = 7
4(3) = 12 -1 = 11
Hope this helps and was correct
