Answer:

<u>f</u><u>(</u><u>-</u><u>2</u><u>)</u><u> </u><u>+</u><u> </u><u>9</u><u> </u><u>is</u><u> </u><u>1</u><u>9</u>

Step-by-step explanation:

f(x) =  - 3x - 2

when x is -9:

f( - 2) =  - 3( - 2) - 2 \\ f( - 2) = 10

sum up with 9, f(-2)+9:

f( - 2) + 9 = 10 + 9 \\  = 19

mr Goodwill [35]

the equation of the line has form

y=kx+b

\left \{ {{5=k*0+b} \atop {9=k*2+b}} \right. \\b=5\\9=2k+5\\2k=4\\k=2, so

y=2x+5

The second line is parallel to the first and runs 7 units lower, so b=5

0=1k+5\\k=-5\\y=-5x+5

Indiana now has 8 different area codes. How many different phone numbers are available within Indiana if the numbers can repeat?
Anna11 [10]

Answer:

Well, this could turn out to be a simple permutation problem: you have ten number choices (0-9) for each digit of a phone number and repetitions are allowed. Technically, there could be as many as \begin{align*}10^{10} = 10,000,000,000\end{align*}, or 10 billion possible phone numbers.
