What do you know about the graph of X= -6 ?​

It is a vertical line at the point of x = -6

Step-by-step explanation:

It is this way because it doesn't state y. So you assume that it means in all places of y so you go to where x is -6 and then draw a vertical line from there across the whole graphing space.

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 answer is d
