Answer:

  E 8 m/s

Step-by-step explanation:

The magnitude of the velocity (the speed) is the number of meters divided by the number of seconds. (That's what meters per second means.)

  |V| = (16 m)/(2 s) = (16/2) m/s = 8 m/s

Velocity is a vector quantity, so must include a <em>direction</em> along with the <em>magnitude</em>.

  V = E 8 m/s

Find the coordinates of the missing endpoint if B is the midpoint of AC. C(-6,-2),B(-3,-5)
Margaret [11]

Answer:

  A = (0, -8)

Step-by-step explanation:

  B = (A+C)/2 . . . . the midpoint is the average of the end points

  A = 2B -C = 2(-3, -5) -(-6, -2) . . . solve for A, substitute point values

  A = (0, -8)

Which system of equations below has infinitely many solutions? y = –3x 4 and y = –3x – 4 y = –3x 4 and 3y = –9x 12 y = –3x 4 and
Flura [38]

the equations y = –3x + 4 and 3y = –9x + 12 have infinitely many solutions. option B is correct.

<h3>What is the linear system?</h3>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Condition for the parallel lines.

L1,  ax + bx + c = 0

L2, dx + ey + f = 0

If \rm \dfrac{a}{d} = \dfrac{b}{e} = \dfrac{c}{f} then lines have infinitely many solutions.

<h3>Which system of equations below has infinitely many solutions?</h3>

y = –3x + 4 and 3y = –9x + 12

On comparing we have

a = -3 , b = 1, and c = 4

d = -9 , e = 3, and f = 12

Then their ratio will be

\rm \dfrac{1}{3} = \dfrac{-3}{-9} = \dfrac{4}{12}\\\\\rm \dfrac{1}{3} = \dfrac{1}{3} = \dfrac{1}{3}

Hence  y = –3x + 4 and 3y = –9x + 12 have infinitely many solutions.

Thus the option B is correct.

To shift the graph of an equation some number of units to the __________, you
Zina [86]

Answer:

A

Step-by-step explanation:

it's A because if you're adding x from each number in the equation you would shift to the left causing the graph to become more positive but if you subtract x you would shift to the right causing the graph to become more negative.
