Alright so I'm coming up with this on the fly; you have the first six letters (a,b,c,d,e,f) and 0-9 and your ten numbers. calculate the amount of possible combinations for the letters by simply writing them down.
ab, ac, ad, ae, a f- five
bc, bd , be, bf- four
cd, ce, cf- three
de, df- two
ef,- one.
adding these all together gets a total of 15 for the letters. now the numbers
01, 02, 03, 04, 05, 06, 07, 08, 09- nine
12, 13, 14, 15, 16, 17, 18, 19- eight
23, 24, 25, 26, 27, 28, 29- seven
34, 35, 36, 37, 38, 39- six
45, 46, 47, 48, 49- five
56, 57, 58, 59- four
67, 68, 69- three
78, 79- two
89- one
added together with a total of 45 combinations.
alright so, 45 different number combinations and 15 letter combinations. multiplying 15 by 45 should tell you the total possible combinations for a two letter and two number serial-number

Solve this equation. Enter your answer in the box. 75 â€"" 3. 5y â€"" 4y = 4y 6.
Answer:
a) y-intercept of AB is 56/5
b) equation of line CD is:
y = -7/5x + 12
Step-by-step explanation:
a) If the coordinates of point A are (8 , 0) and the coordinates of point B are (3 , 7), the y-intercept of AB is ___
We are given the points A(8,0) and point B (3,7)
We need to find y-intercept i.e b
Finding slope of points A and B = y₂ - y₁/x₂ - x₁
=7-0/3-8
=7/-5
= - 7/5
So, finding y intercept b by using equation
y = mx+b
And considering point A (8,0) x = 8 and y = 0 and m = -7/5
0 = 8(-7/5) + b
0 = -56/5 + b
=> b = 56/5
So, y-intercept of AB is 56/5
b) If the coordinates of point D are (5 , 5), the equation of line CD is y = __
Since AB || CD
both will have same slope
i.e m = -7/5
we need to find y-intercept given point D (5,5)
y = mx+b
5 = -7/5(5)+b
5 = -7 + b
=> b = 5+7
=> b = 12
So, equation of line CD is:
y = -7/5x + 12
