Is y =3/4x +2 And -6x+8y=16 parallel or coincident

Rudiy27

Answer:

parallel

Step-by-step explanation:

y=3/4x+2

Multiply the equation by 8:

8y=6x+16

(8y-6x)=16

and you can clearly see that they're same

Write each of the following as a function of theta.<br> 1.) sin(pi/4 - theta) 2.) tan(theta+30°)

Paladinen [302]

Step-by-step explanation:

Let x represent theta.

$\sin( \frac{\pi}{4} - x )$

Using the angle addition trig formula,

$\sin(x - y) = \sin(x) \cos(y) - \cos(x) \sin(y)$

$\sin( \frac{\pi}{4} ) \cos(x) - \cos( \frac{\pi}{4} ) \sin(x)$

$( \frac{ \sqrt{2} }{2}) \cos(x) - (\frac{ \sqrt{2} }{2} )\sin(x)$

Multiply one side at a time

Replace theta with x , the answer is

$\frac{ \sqrt{2} \cos(x) }{2} - \frac{ \sin(x) \sqrt{2} }{2}$

2. Convert 30 degrees into radian

$\frac{30}{1} \times \frac{\pi}{180} = \frac{\pi}{6}$

Using tangent formula,

$\tan(x + y) = \frac{ \tan(x) + \tan(y) }{1 - \tan(x) \tan(y) }$

$\frac{ \tan(x) + \tan( \frac{\pi}{6} ) }{1 - \tan(x) \tan( \frac{\pi}{6} ) }$

Tan if pi/6 is sqr root of 3/3

$\frac{ \tan(x) + ( \frac{ \sqrt{3} }{3} ) }{1 - \tan(x) (\frac{ \sqrt{3} }{3} ) }$

Since my phone about to die if you later simplify that,

you'll get

$\frac{(3 \tan(x) + \sqrt{3} )(3 + \sqrt{3} \tan(x) }{3(3 - \tan {}^{2} (x) }$

Replace theta with X.

An arithmetic sequence has a common difference of 2 and contains the value 86 at some point in the sequence. Which of the follow

shusha [124]

Answer:

B. $a_{n} = a_{n-1}+2$ ; $a_{1} = 2$

Step-by-step explanation:

According to the statement, we find that the following two conditions must be observed:

$a_{i} = 86$ (Eq. 1)

$a_{i}-a_{i-1} = 2$ (Eq. 2)

Since the difference between two even numbers leads to another even number. Hence, $a_{1}$ must be an even number and the correct answer is B.

Turn 92.004 mixed number reduced to the lowest term

sineoko [7]

we can turn any decimal number to a fraction by <u>using as many zeros at the bottom as there are decimals and losing the dot atop</u>, so let's see, we have 3 decimals in this case, so we'll use 3 zeros at the bottom.

$\bf \underset{\textit{three decimals}}{92.\underline{004}}\implies \cfrac{92004}{\underset{\textit{three zeros}}{1\underline{000}}}\implies \stackrel{simplified}{\cfrac{25001}{250}}\implies 92\frac{1}{250}$

recall that to turn an improper fraction to mixed, we divide numerator by denominator, and the quotient is the number alone and the numerator is the remainder of the division.
