The vertex form is y=7(x+1)²-3 which is vertex form
The appropriate choice is ...
1) 4x-5y=-5 and 3x+10y=-20
10 is the least common multiple of 5 and 2
Answer:
<em>The concentration of the new mixture is 46%</em>
Step-by-step explanation:
The first solution of 5 fl. oz. is concentrated at 2% alcohol. The amount of alcohol in the solution is:
5*2/100=0.1 fl. oz.
The second solution of 11 fl. oz. is 66% alcohol. The amount of alcohol in the solution is:
11*66/100=7.26 fl. oz.
The total alcohol in the mixture is
0.1 + 6.6 = 7.36 fl. oz.
The total amount of the mixture is:
5 + 11 = 16 fl.oz.
The concentration of the new mixture is:
7.36 / 16 * 100 = 46%
The concentration of the new mixture is 46%
The one-time setup fee is $5, and the cost per copy is $10 thus the total cost is 10 times the number of copies plus 5.
