Solution-

f(x)=\frac{x^{2}+12x+27 }{x^{2} +4x+3} =\frac{x^{2}+9x+3x+27 }{x^{2} +3x+x+3}=\frac{(x+3)(x+9)}{(x+3)(x+1)}

Equating the denominator to 0,

⇒ (x+3)(x+1) = 0

⇒ x= -3, -1

∴ Discontinuities of the function f(x) is at -3, -1

As (x+3) is also a factor of the numerator, you will have what's called a removable discontinuity. That will show up as a hole in the graph.

∴ At x = -3, you will have removable discontinuity.

Which equation shows the inverse property of multiplication?
serious [3.7K]

Answer:

C

Step-by-step explanation:

The options are:

<em>A. 4 + (-4) = 0 </em>

<em>B. -8 + (-3) = -3 + (-8) </em>

<em>C. 2 </em>×<em> 1/2 = 1 </em>

<em>D. 8/5 + 0 = 8/5</em>

<em />

The inverse property of multiplication states that the product of a number and its inverse is one.

The inverse of 2 is 1/2. The multiplication of 2 × 1/2 = 1 , as the property states.

Test is worth 50 points; test score of 84% idk
aleksklad [387]
84% of 50 is 42. So if your test was graded out of 50 you would've gotten 42/50. If you multiply 50 by 2 (50x2), you have 100, so then you'd just divide the 84% by 2 so you'd get 42%
