Answer:

−2x + 21

Without parenthesis, the answer would be different.

Step-by-step explanation:

1) Distribute the Negative Sign:

4x + 9 + <em>−1</em>(6x−12)

4x + 9 + <em>−1</em>(6x) + (<em>−1</em>)(−12)

4x + 9 + −6x + 12  

2) Combine Like Terms:

<u>4x</u> + <u><em>9</em></u> + <u>−6x</u> + <u><em>12 </em></u>

(4x + −6x) + (9 + 12)

−2x + 21

A point on the terminal side of an angle theta in standard position is (negative 24 comma 18 ). Find the exact value of each of
Vitek1552 [10]

Answer:

(I)Sin Θ=4/5

(II) Cos Θ =-3/5

(III) Tan Θ = -4/3

(IV) Cosec Θ = 5/4

(V) Sec Θ = -5/3

(VI) Cot Θ = -3/4

Step-by-step explanation:

(-24,18)

This lies in the second quadrant from the diagram.

Note that the angle is at the origin (0,0).

Using Pythagoras triples(18,24,30)

Hypotenuse = 30

Opposite=-24

Adjacent=18

(I)Sin Θ= Opposite/Hypotenuse

=-24/30=-4/5

Note: (Sine is Positive in the Second Quadrant)

Sin Θ =4/5

(II) Cos Θ = Adjacent/Hypotenuse

=18/30=3/5

Since Cosine is negative in the Second Quadrant

Cos Θ=-3/5

(III) Tan Θ = Opposite/Adjacent

Tan Θ = -24/18= -4/3

(IV) Cosec Θ = 1/Sin Θ = 5/4

(V) Sec Θ = 1/cos Θ = -5/4

(VI) Cot Θ = 1/tan Θ = -3/4
