If sin=2/3 and tan is less than 0, what is the value of cos

Sonbull [250]

tangent is less than 0 or tan(θ) < 0, is another way to say tan(θ) is negative, well, that only happens on the II Quadrant and IV Quadrant, where sine and cosine are different signs, so we know θ is on the II or IV Quadrant.

$\bf sin(\theta )=\cfrac{\stackrel{opposite}{2}}{\stackrel{hypotenuse}{3}}\qquad \impliedby \textit{let's find the \underline{adjacent side}} \\\\\\ \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies \pm\sqrt{c^2-b^2}=a \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases}$

$\bf \pm\sqrt{3^2-2^2}=a\implies \pm\sqrt{5}=a\implies \stackrel{\textit{II Quadrant}}{-\sqrt{5}=a} \\\\[-0.35em] ~\dotfill\\\\ ~\hfill cos(\theta )=\cfrac{\stackrel{adjacent}{-\sqrt{5}}}{\stackrel{hypotenuse}{3}}~\hfill$

Solve each system by elimination <br> -4x+y=-10<br> 6x-y=16

miss Akunina [59]

The y variable in both equations are opposites. So, we can add the two systems together to eliminate y and solve for x.

-4x + y = -10

6x - y = 16

2x = 6

2 × 3 = 6.

x = 3. Now we have to solve for y. Let's use 6x - y = 16.

6(3) - y = 16

18 - y = 16

18 - 2 = 16, so y = 2.

x = 3

y = 2.

Or if you have to put it in coordinate form: (3, 2)

What does n equal? btw this is 6th grade! also < Is between 3 and 5

11Alexandr11 [23.1K]

Answer:

n < 4

Step-by-step explanation:

$\frac{1}{2} n+3$

-3 -3

$\frac{1}{2} n$ < 2

divide both sides by $\frac{1}{2}$

n < 4

Hope this helps!!!
