F(x)=5*2
the f(x) stands for a normal X like any other algebraic equation. so all it is, is 5 times 2, which is 10.
so,
f(x)=5*2
f(x)=10<span />
The U.S RDA for protein is 46g for girl
If a piece of fried chicken contains 23g
To find the pieces of chicken she is to eat to satisfy the U.S RDA requirement,
The number of pieces of chicken is
![\text{Number of pieces}=\frac{U.S.\text{ RDA g protein required for a girl}}{g\text{ of protein in a piece of chicken}}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20pieces%7D%3D%5Cfrac%7BU.S.%5Ctext%7B%20RDA%20g%20protein%20required%20for%20a%20girl%7D%7D%7Bg%5Ctext%7B%20of%20protein%20in%20a%20piece%20of%20chicken%7D%7D)

Hence, the right option is B
The answer is 6 that's how many places its away from zero.
It will be a horizontal line at y=7 and shaded above. If you have pictures of the graph I can show which one it would be.
