Graph each function and determine the y-intercept, then use the graph to determine the approximate value of the given expression.
y = 34,312
a. 1; 3.7
C. 0; 3.9
b. 1; 2.9
d. 0: 3.5

answer: check all that apply, where the options?

step-by-step explanation:

r and t.

both are 64 degrees.

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
