Answer:
Step-by-step explanation:
"Vary directly" is another way of saying "directly proportional".
In simple English, this just means, as one increases, the other increases too.
a = 6
b = 4
The question says find out what a is when b is 16.
First, lets find how many times larger b has gotten.
16/4 = 4
b had gotten 4 times bigger to go from b=4 to b=16
If a is varying directly, it means that it will also get 4 times bigger.
Therefore, a = 6 x 4 = 24
The question is asking to calculate the zeros of the function f(x)=(5x^2+2x)/x, base on that and in my further calculation, the possible answer would be x=5. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications

Answer:
4845
Step-by-step explanation:
