Step-by-step explanation:
x= 0 y= 5
y=mx+b
5=b
x= -3 y= -4
-4= -3m +5
-3m = -9
m= 3
y= 3x +5
Let, amount of 14% solution required is x ounces.
So, amount of 8% solution will be ( 28 - x ) ounces.
Now, mathematical equation is :

Therefore, amount of 14% solution and 8% solution required is 4 ounces and 24 ounces respectively.
Hence, this is the required solution.
So what do you need us to do for you?
Answer:
The solution is
.
Step-by-step explanation:
The best way to solve this exponential equation is applying the logarithm of base 10 to each side of the equality.
It is also important to remember the following logarithm proprierty:

So






The solution is
