Solve the system using elimination. x + 2y = –6 3x + 8y = –20 (–4, –1) (–4, 4) (–1, –4) (3, 1)
Orlov [11]

x + 2y =  - 6 >  >  > 3x =  - 18 - 6y
- 18 - 6y + 8y =  - 20 >  >  > 2y =  - 2 >  > y =  - 1
so x=4

If cosine theta almost-equals 0.3090, which of the following represents approximate values of sine theta and tangent theta, for
Zepler [3.9K]

Answer:

\sin \theta = 0.9511 and \tan \theta = 3.078

Step-by-step explanation:

Given that, \cos \theta = 0.309.

Now, we have to calculate the values of \sin \theta and \tan \theta.

We know the identity that, \sin^{2}\theta + \cos^{2}\theta  = 1

So, \sin \theta = \sqrt{1 + \cos^{2}\theta} = \sqrt{1 - (0.309)^{2}} = 0.9511 {Since 0 \leq  \theta \leq  90^{\circ}}

Now, \sec \theta = \frac{1}{\cos\theta} = \frac{1}{0.309} = 3.236

Then, we know the identity, \sec^{2}\theta - \tan^{2}\theta  = 1

So, \tan \theta = \sqrt{\sec^{2}\theta - 1} = \sqrt{(3.236)^{2} - 1} = 3.078 (Answer) {Since 0 \leq  \theta \leq  90^{\circ}}

x: positive response

y: negative response

then the score is:

2x - 3y

A career placement test eliminates a profession when a person receives a score of 18 or less, that's represented by the following inequality:

2x - 3y ≤ 18
