Answer:
35
Step-by-step explanation:
f(x) = 5x means you multply the given f function by 5
f(7) = 5×7 ➡35
Answer:

The value of S(50) is 22 in means the amount of sodium iodine in the mixture is 22 when 50 milliliters of the 20% solution used.
Step-by-step explanation:
It is given that a chemist working on a flu vaccine needs to mix a 20% sodium-iodine with a 60% sodium-iodine to obtain a 70-milliliter mixture.
Let x be the number of milliliters of the 20% sodium-iodine.
Number of milliliters of the 60% sodium-iodine = 70-x
The amount of sodium iodine in the mixture is 20% of x and 60% of (70-x).



Therefore,the required function is
.
Substitute x=50 in the above equation.


The value of S(50) is 22 in means the amount of sodium iodine in the mixture is 22 when 50 milliliters of the 20% solution used.

I’m pretty sure the domain is all real numbers because the arrows are pointing in either direction infinitely so there are infinite values that could be used as the x-value
