Y=Mx+b m is the slope and b is the y intersect so where x hits 0
Answer:
5a²+22a+8
Step-by-step explanation:
(5a+2)(a+4)
5a² + 20a + 2a + 8
5a² + 22a + 8
Answer:
The equation of line a is y = x
The equation of line b is y =
x
Step-by-step explanation:
The equation of the proportional is y = m x, where
- m is the slope of the line (constant of proportionality)
The rule of the slope of a line is m =
, where
- (x1, y1) and (x2, y2) are two points on the line
∵ Line a passes through points (0, 0) and (3, 3)
∴ x1 = 0 and y1 = 0
∴ x2 = 3 and y2 = 3
→ Substitute them in the rule of the slope above
∵ m = 
∴ m = 1
→ Substitute in the form of the equation above
∴ y = (1)x
∴ y = x
∴ The equation of line a is y = x
∵ Line b passes through points (0, 0) and (3, 2)
∴ x1 = 0 and y1 = 0
∴ x2 = 3 and y2 = 2
→ Substitute them in the rule of the slope above
∵ m = 
∴ m = 
→ Substitute in the form of the equation above
∴ y = (
) x
∴ y =
x
∴ The equation of line b is y =
x

Step-by-step explanation:
Twins can be identical boys, identical girls, non-identical boys, non-identical girls or one boy and one girl.
For the triplets, first list all possibilities with children sexes:
3 boys
3 girls
2 boys and 1 girl
2 girls and 1 boy.
Hence, all possible combinations are:
3 identical boys
2 identical boys and 1 non-identical boy
3 non-identical boys
3 identical girls
2 identical girls and 1 non-identical girl
3 non-identical girl
2 identical boys and girl
2 non-identical boys and girl
2 identical girls and boy
2 non-identical girls and boy
So 6 times 3 equals 18 then you add 52 witch equals 70 then you subtract 24 and get 46 and then yo do 16 divided by 2 witch equals 8 then you do 46 minus 8 witch equals 38 so 38 is the answer :D
