german

Answer:

It gives you 28 different 10-digit numbers

Step-by-step explanation:

The leftmost position digit can not be 0 --- hence, it is 1, since there is no other possibilities.

The rightmost position (the "ones" position) must be 0 to provide an even number.

Hence, you have 8 remaining positions to fill with six ones and two zeros by an arbitrary way.

You can place two digits of zero among 8 positions by \frac{C 2}{8} = \frac{8=7}{2}different ways = 4*7 = 28 different ways,

Answer:

The correct answer is C. y = 3/4x - 12

Step-by-step explanation:

In order to find this, we must first note that the slope will be 3/4. We can tell this because parallel lines have the same slope. Next, we use that along with the point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - -18 = 3/4(x - -8)

y + 18 = 3/4 (x + 8)

y + 18 = 3/4x + 6

y = 3/4x - 12
