Which number line shows the graph of x 11

The second one

Step-by-step explanation:

Since the equation is X is greater than or equal to 11, because of the line under it, the "or equal to" it is a closed dot. (If it didn't have that line under it, it would be an open dot.) And, how I like to explain which way the blue arrow goes, the ">" kind of looks like the tip of an arrow, so the blue arrow should go the same way. For example, ">" seems like an arrow going this way "-->", or "<" seems like an arrow going this way "<--"!

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
