Answer:

Options (1) and  (4)

Step-by-step explanation:

Given expression in the question is,

\frac{1}{5}+\frac{2}{3}|2 - x|=\frac{4}{15}

By distribution property,

\frac{1}{5}+|\frac{4}{3}-\frac{2x}{3}|=\frac{4}{15}

Subtract \frac{1}{5} from both the sides of the equation,

\frac{1}{5}+|\frac{4}{3}-\frac{2x}{3}|-\frac{1}{5}=\frac{4}{15}-\frac{1}{5}

|\frac{4}{3}-\frac{2x}{3}|=\frac{4}{15}-\frac{1}{5}

|\frac{4}{3}-\frac{2x}{3}|=\frac{4}{15}-\frac{3}{15}

\frac{2}{3}|2-x|=\frac{1}{15}

Therefore, Options (1) and (4) will be answer.

Answer:

\displaystyle    8

Step-by-step explanation:

we would like to compute the following limit

\displaystyle \lim_{x \to 16} \left( \frac{x - 16}{ \sqrt{x}  - 4}  \right)

if we substitute 16 directly we'd end up

\displaystyle = \frac{16 - 16}{ \sqrt{16}  - 4}

\displaystyle = \frac{0}{ 0}

which isn't a good answer now notice that we have a square root on the denominator so we can rationalise the denominator to do so multiply the expression by √x+4/√x+4 which yields:

\displaystyle \lim_{x \to 16} \left( \frac{x - 16}{ \sqrt{x}  - 4} \times  \frac{ \sqrt{x} +  4 }{ \sqrt{x} + 4 }   \right)

simplify which yields:

\displaystyle \lim_{x \to 16} \left( \frac{(x - 16)( \sqrt{x}  + 4)}{ x  - 16}  \right)

we can reduce fraction so that yields:

\displaystyle \lim_{x \to 16} \left( \frac{ \cancel{(x - 16)}( \sqrt{x}  + 4)}{  \cancel{x  - 16} } \right)

\displaystyle  \lim _{x \to 16} \left(  \sqrt{x }   + 4\right)

now it's safe enough to substitute 16 thus

substitute:

\displaystyle =   \sqrt{16}   + 4

simplify square root:

\displaystyle  =  4   + 4

simplify addition:

\displaystyle  =  8

hence,

\displaystyle \lim_{x \to 16} \left( \frac{x - 16}{ \sqrt{x}  - 4}  \right)  = 8
