Answer:

x=\frac{-1}{6}

Step-by-step explanation:

9(x+1) -4x = 5-(x-3)

9(x+1) -4x = 5-(x-3) \\

9x+9\cdot1-4x=5-\left(x-3\right)

9x+9-4x=5-\left(x-3\right)

\left(9x-4x\right)+9=5-\left(x-3\right)

5x+9=5-\left(x-3\right)

5x+9=5-x+3

5x+9=-x+\left(5+3\right)

5x+9=-x+8

5x+9=-x+8

5x+9+x=-x+8+x

5x+x+9=-x+8+x

6x+9=-x+8+x

6x+9=-x+x+8

6x+9=8

6x+9=8

6x+9-9=8-9

6x=8-9

6x=-1

\frac{6x}{6}=\frac{-1}{6}

x=\frac{-1}{6}

(3Q) Find the amplitude and period of f(t)= -tan.0t
Vanyuwa [196]

Answer:

It has no amplitud and the period is 5pi/2

Step-by-step explanation:

Given a function of the following type:

f(t) = AtanB(t + C)

The function has no amplitud, given that it doesn't have maximum or minimum value.  And the period is given by: pi/B

In this case, we have f(t)= -tan0.4t. Then:

B = 0.4

⇒ Period = pi/0.4 = 5pi/2

Therefore, the answer is: It has no amplitud and the period is 5pi/2
