How many different phone numbers are possible in the area code 503, if the first number cannot start with a 0 or 1
ElenaW [278]

Answer:

8 X 10^(9)

Step-by-step explanation:

Originally we have 10 digit phone numbers excluding the area code.

For each face value we have these in store: 0,1,2,3,4,5,6,7,8,9 (total 10)

But if we exclude 1 and 0 for the first digit, we are left with 8 digits.

8P1 X .......

In a phone number, digits can repeat so we can choose out of these 10 numbers freely after this.

8P1 X 10P1 X 10P1 X...

Adding the area code while assuming 10P1 is just 10...we get:

1 X 1 X 1 X 8 X 10^(9)

= 8000000000

Very interesting question, thanks for the opportunity!

What is the slope of the line whose equation is y−4= StartFraction 5 Over 2 EndFraction.(x−2)?
Yuki888 [10]

For this case we must find the slope of the following equation:

y-4 = \frac {5} {2} (x-2)

By definition, the point-slope equation of a line is given by:

y-y_ {0} = m (x-x_ {0})

Where:

(x_ {0}, y_ {0}): It is a point through which the line passes

m: It's the slope

So, the slope of the given equation is:

m = \frac {5} {2}

Answer:

Option D
