if f(x)=4−x, then the graphs of 1/4f(x) and f(x)−3 both have a y-intercept of 1. Does this mean that multiplying f(x) by 1/4 and subtracting 3 from f(x) transform the graph in the same 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

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer

6+6=12 so that just tells you what it is one half is 6 the next one is 6
