Answer:

Step-by-step explanation:

Given

f(x) = $\frac{(x+2)(x-1)}{(x-3)(x+2)}$ ← cancel (x + 2) on the numerator/ denominator

This creates a discontinuity ( a hole ) at x = - 2

f(x) = $\frac{x-1}{x-3}$

The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be.

x - 3 = 0 ⇒ x = 3 ← excluded value

Thus domain is { x | x ≠ - 2, 3 } → D

PLEASE HELP ME!! Find the measure of angle A: Find the measure of angle B:

g100num [7]

Answer:

Measure of angle A is 65 degrees and measure of angle B is 37 degrees.

Step-by-step explanation: First add all of the degrees of excluding x (4+(-9)) which is -5. Then subtract that from 180 since that is the sum of all the angles in a triangle which gives you 185. Then divide it by the number of "x's" that there are which is 5 which gives you 37. So angle B is x which is 37 degrees and angle a is 2(37)-9 which is 65 degrees. Hope this helps.
