Answer:

$\cos x=\dfrac{8}{f}$

Step-by-step explanation:

Given that,

$\tan x=\dfrac{e}{8}\\\\\sin x=\dfrac{e}{f}$

We need to find the value of cos x.

We know that,

$\tan\theta=\dfrac{\sin\theta}{\cos\theta}$

Using the above relation,

$\dfrac{e}{8}=\dfrac{\dfrac{e}{f}}{\cos x}\\\\\cos x=\dfrac{\dfrac{e}{f}}{\dfrac{e}{8}}\\\\=\dfrac{e}{f}\times \dfrac{8}{e}\\\\=\dfrac{8}{f}$

So, the value of cos x is equal to $\dfrac{8}{f}$ .

Which graph represents this system?<br> 2x-5y=-5<br> y = ² x + 1<br> 5

frosja888 [35]

Answer:

$x = \frac{5(y - 1)}{2} \\ \\ x = \frac{y - 1}{2}$

Step-by-step explanation:

$2x = - 5 + 5y \\ 2x = 5y - 5 \\ x = \frac{5y - 5}{2} \\ \\ y - 1 = 2x \\ \frac{y - 1}{2} = x$
