How to <br> Swoop the decimal

ddd [48]

Answer:

Step-by-step explanation: I don’t really understand what this means, but I think it might. For multiplication of decimals, you would move the decimal point to the left. For division, you’d move the decimal point to the right.

What is the result of subtracting the second equation from the first?<br> -2x+y=0<br> - 7x + 3y = 2

artcher [175]

Answer:

5x - 2y = - 2

Step-by-step explanation:

Given the 2 equations

- 2x + y = 0 → (1)

- 7x + 3y = 2 → (2)

Subtracting (2) from (1) term by term

- 2x - (- 7x) + y - 3y = 0 - 2, that is

- 2x + 7x - 2y = - 2

5x - 2y = - 2

If cos(θ) = 6/8 and θ is in the IV quadrant, then fine:

svetoff [14.1K]

Answer:

a) 1

b) $\frac{4}{3}$

c) = 1

Step-by-step explanation:

We are given the following in the question:

$\cos \theta = \dfrac{6}{8}$

θ is in the IV quadrant.

$\sin^2 \theta + \cos^2 \theta = 1\\\\\sin \theta = \sqrt{1-\dfrac{36}{64}} = -\dfrac{2\sqrt7}{8}\\\\\tan \theta = \dfrac{\sin \theta}{\cos \theta} = -\dfrac{2\sqrt7}{6}\\\\\csc \theta = \dfrac{1}{\sin \theta} = -\dfrac{8}{2\sqrt7}$

Evaluate the following:

$\tan \theta\times \cot \theta =\tan \theta\times\dfrac{1}{\tan \theta} = 1$

$\csc \theta\times \tan \theta\\\\= -\dfrac{8}{2\sqrt7}\times -\dfrac{2\sqrt7}{6} = \dfrac{4}{3}$

$\sin^2 \theta + \cos^2 \theta = 1\\\text{using the trignometric identity}$
