If f(x) equals x/2+8 what is f(x) when x=10

Sphinxa [80]

Answer:

Step-by-step explanation:

Since we want to find f(x) when x equals 10, we can substitute 10 in for x

f(x)=x/2 +8

f(10)=10/2+8

Divide 10 by 2

f(10)=5+8

Add 5 and 8

f(10)=13

So, f(x) when x=10 is 13

$\text{Rational number} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{ Irrational number}$

$3\sqrt{25} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \sqrt{141}\\\\\sqrt{256} \\\\1. \overline{ 1625} \\\\\frac{-11}{151}$

Step-by-step explanation:

Since we believe it

The number sequence is that those which can be described as $\frac{p}{q}$ and that is not ending and recurring. Figures that are unreasonable are also the ones, that are not $\frac{p}{q}$ and therefore are non-ending, non-recurring.
