A website requires a four-digit numerical password in which the digits cannot repeat. How many possible passwords are there? . .
Law Incorporation [45]

Answer:  B) 5040

Step-by-step explanation:

Since total number of digits are 10 ( which are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9)

And, According to the question, website requires a four-digit numerical password in which the digits cannot repeat.

Therefore, required possible arrangement = 10_P_4

=\frac{10!}{(10-4)!}

= \frac{10!}{6!}

= \frac{10\times 9\times 8\times 7\times 6!}{6!}

Find the equation of a line in slope-intercept form that passes through the points (-2, 20) and (3, -10).
solniwko [45]
Simple...

you have: (-2,20) and (3,-10,)

Using \frac{ y_{1}- y_{2}  }{ x_{1}-  x_{2} } to find slope--->>>

\frac{20--10}{-2-3} = \frac{30}{-5}

=-6

m=-6

Using y=mx+b to find the equation of the line-->>>(Use any of the coordinates)

(-2,20)

20=-6(-2)+b

20=12+b

20=12+b
-12  -12

8=b

y=-6x+8

Thus, your answer.
