Answer:

36,000 possible codes.

Step-by-step explanation:

I guess you want the total number of arrangements possible.

The first digit  can be any number from 0 to 8. the middle numbers must each be any number from 0 to 9 and the last digit must be 2,4,6 or 8.

So the number of arrangements possible =  9 * 10 * 10 * 10 * 4

= 36,000.

1/2 or (1/2)² which value is greater​
Ket [755]

Answer:

when a expression is squared (²) that means it is multiplyed by itself.

Step-by-step explanation:

(1/2)² = (1/2 x 1/2)

1 squared = 1

2 squared = 4

1/4 is smaller than 1/2. 1/2 is greater than (1/2)²

Elimination_4x_2y=14<br> _10x+7y=_24
Gnesinka [82]

Answer:

The answer is x=-\frac{50}{8}  and y=\frac{11}{2}.

Step-by-step explanation:

Given:

-4x-2y=14

-10x+7y=-24

Now, to solve it by elimination:

-4x-2y=14   ......(1)

-10x+7y=-24 ......(2)

So, we multiply the equation (1) by 7 we get:

-28x-14y=98

And, we multiply the equation (2) by 2 we get:

-20x+14y=-48

Now, adding both the new equations:

-28x-14y+(-20x+14y)=98+(-48)

-28x-14y-20x+14y=98-48

-28x-20x-14y+14y=50

-8x=50

<em>Dividing both the sides by -8 we get:</em>

x=-\frac{50}{8}

Now, putting the value of x in equation (1):

-4x-2y=14

-4(-\frac{50}{8})-2y=14

\frac{200}{8} -2y=14

25-2y=14

<em>Subtracting both sides by 25 we get:</em>

-2y=-11

<em>Dividing both sides by -2 we get:</em>

y=\frac{11}{2}

Therefore, the answer is x=-\frac{50}{8}  and y=\frac{11}{2}.

d = a2-a1 = 13-9 = 4

The formula for an

an =a1+d(n-1)

an = 9 + 4(n-1)

Distributing

an = 9+4n-4
