O a. 16 - x1 = 5
Ob. 11 – x1 = 1
Oc. 11 - x = 6
O d. x - 61 = 5

Answer 1

$\\ \sf\longmapsto |11-x|=1$

As we can see

$\\ \sf\longmapsto D_f=\[1,11\]$

So having 1 and 11 as domain we can say the equation is

$\\ \sf\longmapsto |11-x|\geqslant 1$

• As it's greater than and equal to the answer can be equal to (=) form.
