Which equation represents the model shown below

Alona [7]

Answer:

-4x - 3 = -8

Step-by-step explanation:

On our left, we have -x in 4 places = 4(-x) = -4x

And on the left, we also have -1 in 3 places = 3(-1) = -3

Altogether in our left, we have: -4x +(-3)

That is: -4x - 3

On our right, we have -1 in 8 places, which is 8(-1) = -8

Therefore, the equation that represents the model would be:

-4x - 3 = -8

Sec^2 theta/tan theta = sec theta x csc theta

Andreas93 [3]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

• tan x = $\frac{sinx}{cosx}$

• sec x = $\frac{1}{cosx}$ , csc x = $\frac{1}{sinx}$

Consider the left side with x = Θ

$\frac{sec^2x}{tanx}$

= $\frac{1/cos^2x}{\frac{sinx}{cosx} }$

= $\frac{1}{cos^2x}$ × $\frac{cosx}{sinx}$

= $\frac{1}{cosxsinx}$

= $\frac{1}{cosx}$ × $\frac{1}{sinx}$

= secxcscx = right side ⇒ verified
