The conversion is

x =  r \cos \theta

y = r \sin \theta

So

\dfrac y x = \tan \theta

We're given the fairly unusual

\theta = -\frac 5 2

It's fairly unusual because usually an angle is given in degrees or radians, and typically the radians are a fraction times pi. We'll assume radians.

\dfrac y x = \tan \theta = \tan(-5/2) \approx 0.747

Ah, there's our .75. The approximate answer is

y = 0.75 x

Third choice.

The exact answer is

y = x \tan( -\frac 5 2)

also a line through the origin.

How do i do 3=4(x-2)+5-3x
SashulF [63]

Answer:

6 = x

Step-by-step explanation:

first, we simplify the parenthesis by distributing the 4

3 = 4(x - 2) + 5 - 3x

3 = 4x - 8 + 5 - 3x

then, you add like terms

3 = x - 3

then add 3 to both sides to isolate x

6 = x

I think it the third one but need a double check
makkiz [27]

Answer:

The first answer is correct.

Step-by-step explanation:

Line 5 says that the reason is due to substitution

Line 3 says m∠ SQT equals 180°

If we substitute 180° into the spot for m∠ SQT in line 4, we get solution option 1
