Answer:

  see below

Step-by-step explanation:

It is easiest to compare the equations when they are written in the same form.

The first set can be written in slope-intercept form.

  y = 2x +7

  y = 2x +7 . . . . add 2x

These equations are <em>identical</em>, so have infinitely many solutions.

__

The second set can be written in standard form.

  y +4x = -5

  y +4x = -10

These equations <em>differ only in their constant</em>, so have no solutions.

__

The third set is already written in slope-intercept form. The equations have <em>different slopes</em>, so have exactly one solution.

How many different ways can four team members from the group of fifteen be lined up for a photograph?
damaskus [11]

Answer:

32760

Step-by-step explanation:

This is a permutation of 15 objects taken 4 at a time.  To calculate this, we use the formula:

_nP_r=\frac{n!}{(n-r)!}

In our case, n is 15 and r is 4:

_{15}P_4=\frac{15!}{(15-4)!}=\frac{15!}{11!}=32760
