Instructions: Find the equation of the line through point (−4,1) and parallel to y=−12x−2. Use a forward slash (i.e. "/") for fr
USPshnik [31]

Answer:

y = - 12x - 47

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 12x - 2 ← is in slope- intercept form

with slope m = - 12

Parallel lines have equal slopes, thus

y = - 12x + c ← is the partial equation

To find c substitute (- 4, 1 ) into the partial equation

1 = 48 + c ⇒ c = 1 - 48 = - 47

y = - 12x - 47 ← equation of parallel line

If you have a density of 3g/ml and a volume of 10 ml, what is the mass?
balandron [24]

Alright, lets get started.

If you have a density of 3g/ml and a volume of 10 ml

means density = 3 g / ml

Volume = 10 ml

Formula for density, mass,  volume will be

density = \frac{mass}{volume}

Plugging the value

3 = \frac{mass}{10}

Multiplying 10 in both sides

10*3 = \frac{mass}{10} *10

mass = 30 gm

Hence the answer is 30 gm.   :    Answer

Hope it will help :)

If PQ = 3, QR = 2x, and PR = 3x, what is QR?
aniked [119]

Answer:

6

Step-by-step explanation:

It is ALWAYS helpful to sketch the appropriate figure.

That will make clear that 3x = x+4, by the definition of midpoint.

Then you solve the equation and you get x=2, so that PQ = 6.
