can someone help me with this one
You need a 55% alcohol solution. On hand, you have a 330 mL of a 80% alcohol mixture. How much pure water will you need to add to obtain the desired solution?
Step-by-step explanation:
Answer:
x = -3, y = -4
Step-by-step explanation:
Double the first equation to get 6x - 2y = -10
Now just add the two together and get x = -3. Plug this back in to get y = -4.
1.) 16
2.) 3
3.) 2.7
These are the answers
Step-by-step explanation:
If the polynomial is rational, then one of zeros is 3 + 2i.
We are also given f(x) is decreasing function, it means the leading coefficient is negative.
<u>The factors would be:</u>
- f(x) = - (x - 7)(x - (3 - 2i))(x - (3 + 2i)
or
- f(x) = - (x - 7)(x - 3+ 2i)(x - 3 - 2i)
