A transformation of the form f(bx) represents a horizontal stretch if |b| is between 0 and 1.
To find function g, start with function f and replace all x-values with .
So, the graph of g(x) will be a line with a slope of and a y-intercept of 0 as shown.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

the answer is 489

step-by-step explanation:

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
