The discontinuities are x=-4. Because it is a fraction, you cannot divide by zero so if the denominator is set to equal zero, which it will if x=-4, the function will be be undefined

F(x) = 2x^2 – 3x – 9<br> g(x) = 4x^2 - 9<br> Find ( f/g)(x).
Tomtit [17]

Answer:

(f/g)x = (x - 3)/(2x - 3)

Step-by-step explanation:

Try and see if f(x) can be factored.

g(x) = (2x - 3) (2x + 3)

That means that perhaps f(x) has one of these two factors.

(2x   3)(x   3)

You want the 2x and 3 to multiply. The middle term has to be -, so when 2x and 3 multiply likely it is 3 that gives you the minus answer.

(2x + 3)(x - 3) should be the way f(x) factors, and it is.

f(x) / g(x) =<u> (2x + 3) (x - 3)</u>

                 (2x + 3)(2x - 3)

2x + 3 cancels. The answer is

(f/g)x = (x - 3)/(2x - 3)

A triangle has an angle that measures 80°. The other two angles are in a ratio of 9:11. What are the measures of those two angle
Alekssandra [29.7K]

Answer:

The answer is 45° and 55 °.

180° - 80° = 100°

Then add the two numbers from the ratio:

9 + 11 = 20

The divide 100 from 20.

100 ÷ 20 = 5

Then multiply it to two numbers from the ratio:

9 × 5 = 45 and 11 × 5 = 55

I hope it helps.

Find the value of x, 110°, 4x+2, and if you can help with steps that would be great :,)
Helen [10]

Answer:

x = 17

Step-by-step explanation:

The two angles with measures form a linear pair and are supplementary.

The measures of supplementary angles has a sum of 180°.

If you add the two given measures, the sum must equal 180°.

4x + 2 + 110 = 180

4x + 112 = 180

4x = 68

x = 68/4

x = 17
