B. 136

Step-by-step explanation:

∆ABC is similar to ∆EDC, therefore the ratio of their corresponding side lengths would be the same.

Thus:

AC/EC = AB/ED

(144 - x)/x = 51/3

(144 - x)/x = 17/1

Cross multiply

(144 - x)*1 = 17*x

144 - x = 17x

144 - x + x = 17x + x

144 = 18x

Divide both sides by 18

144/18 = 18x/18

8 = x

x = 8

✔️AC = 144 - x

Plug in the value of x

AC = 144 - 8

AC = 136

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
