Answer: The correct answer is B) division.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

3(x + 4) = 18 (Given)

3x + 12 = 18 (Distributive Property)

3x = 6 (Subtraction)

x = 2

To obtain the result, in the last step we have to divide both sides by 3.

Mathematically speaking:

3x÷3 = 6÷3

x =2

So, the correct answer is B) division.

Find the exact values of cos (3pi/4radians) and sin (3pi/4 Radians)

ryzh [129]

$\cos\dfrac{3\pi}{4}=\cos\left(\pi-\dfrac{\pi}{4}\right)=-\cos\dfrac{\pi}{4}=-\dfrac{\sqrt2}{2}$

$\sin\dfrac{3\pi}{4}=\sin\left(\pi-\dfrac{\pi}{4}\right)=\sin\dfrac{\pi}{4}=\dfrac{\sqrt2}{3}$

Look at the picture.

$\dfrac{\pi}{2} < \dfrac{3\pi}{4} < \pi\\\\therefoere\\\\\cos\dfrac{3\pi}{4} < 0\ and\ \sin\dfrac{3\pi}{4} > 0$

Pd). <br>cot x/sec x <br>show that -=cos ecx -sin x<br>

forsale [732]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

• cot x = $\frac{cosx}{sinx}$

• sec x = $\frac{1}{cosx}$ and cosec x = $\frac{1}{sinx}$

Consider the left side

$\frac{cotx}{secx}$

= $\frac{cosx}{sinx}$ × cosx

= $\frac{cos^2x}{sinx}$

= $\frac{1-sin^2x}{sinx}$

= $\frac{1}{sinx}$ - $\frac{sin^2x}{sinx}$

= cosec x - sin x

= right side ⇒ verified

The graph of a line has a slope of 3 and passes through the point (–4, –5). What is the equation of the line in point-slope form

Contact [7]

Y + 5 = 3(x + 4)
Because in point-slope format, it is: y-(y-value) = m (x-(x-value)), where m=slope, and the point: (-4,-5) can be written as: (x-value,y-value),
So y - -5 = 3 (x - -4)
