For each linear equation write the slope of a line parallel to the given line. 3x - 2y = 8 ​
PSYCHO15rus [73]

We first need to convert 3x - 2y = 8 into y = mx + b form.

To do this, we first subtract 3x from

both sides and we have -2y = -3x + 8.

Now divide both sides by -2 and we have y = 3/2x - 4.

Now, we want the slope parallel to this given line.

Since the m or the coefficient of the x term

represents slope, we know this line has a slope of 3/2.

Now, it's important to understand that parallel lines have the same slope.

So the slope of the line parallel to this line will also be 3/2.

What is the arc length when theta=2 pi/5 and the radius is 6 cm
Crank

Answer:

The length of the arc is 7.536cm

Step-by-step explanation:

To solve this problem we need to use the circumferenc formula of a circle:

c = circumference

r = radius = 6cm

π = 3.14

c = 2π * r

we replace with the known values

c = 2 * 3.14 * 6cm

c = 37.68cm

The length of the circumference is 37.68cm

Now we calculate the fraction that corresponds to this arc with the rest of the circumference

(2 pi /5) / (2pi) = 1/5

now we multiply the circumference by the fraction

37.68cm  * 1/5 = 7.536cm

The length of the arc is 7.536cm

10 POINTS + BRAINLIEST ANSWER!!
alexandr1967 [171]
The answer would be D. 60,000 because the problem tells us V (volume) is equal to 50 times the number of moles. We know there are 1,200 moles, so multiple 50*1,200 to get 60,000.
