Answer:  They study patterns in light bands that are separated from starlight by the spectroscope.

Step-by-step explanation: Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.

Through: (-5, -5), parallel to y = 3/5x + 3
Komok [63]

Answer:

\displaystyle y=\frac{3}{5}x-2

Step-by-step explanation:

We want to find the equation of a line parallel to:

\displaystyle y=\frac{3}{5}x+3

And passes through (-5, -5).

Recall that parallel lines must have the same slope.

Since the slope of our old line is 3/5, the slope of our new line must also be 3/5.

So, we know that the slope of our new line is 3/5 and it passes through (-5, -5).

Now, we can use the point-slope form given by:

y-y_1=m(x-x_1)

We will let (-5, -5) be (x₁, y₁). m is the slope or 3/5. Hence:

\displaystyle y-(-5)=\frac{3}{5}(x-(-5))

Simplify:

\displaystyle y+5=\frac{3}{5}(x+5)

Distribute:

\displaystyle y+5=\frac{3}{5}x+3

Subtract 5 from both sides:

\displaystyle y=\frac{3}{5}x-2

And we have our equation.

Find the value of x in (5,x),(x,14) so that the line line containing them is 7/2.
aivan3 [116]

Answer:

7

Step-by-step explanation:

If what you meant by 7/2 was the slope of the line then we can plug in the two points into the slope formula to get our line:

14-x/x-5 = 7/2

This means that 14 - x = 7 and x - 5 = 2. We can see that 14 -7 = 7 and 7 - 5 = 2,

meaning that the value of x should be 7.
