Answer:

5 1/3

Step-by-step explanation:

f(1/2) means the value of f(x) when x = 1/2.

So we substitute for x:-

f(1/2) = 2/3(1/2) + 5

= 2/6 + 5

= 5 1/3 (answer)

Solveing systems of equations by substitution y=6x-11 -2x-3y=-7

sergiy2304 [10]

$\bf \begin{cases} \boxed{y}=6x-11\\ \cline{1-1} -2x-3y=-7 \end{cases}\qquad \implies \stackrel{\textit{substituting \underline{y} in the 2nd equation}}{-2x-3\left( \boxed{6x-11} \right)=-7}$

$\bf -2x-18x+33=-7\implies -20x+33=-7\implies -20x=-40 \\\\\\ x=\cfrac{-40}{-20}\implies \blacktriangleright x=2 \blacktriangleleft \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{since we know that }}{y=6x-11}\implies y=6(2)-11\implies y=12-11\implies \blacktriangleright y=1 \blacktriangleleft \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill (2,1)~\hfill$
