Answer:
3 girls and 4 boys
Step-by-step explanation:
Writing the number of girls in the family as g and the number of boys in the family as b,
we know that each girl has twice as many brothers as sisters. Therefore, the amount of boys in the family (b, or how many brothers each girl has) is twice the number of the amount of girls in the family (g) minus 1 (g-1) (subtract 1 because each girl's number of sisters does not include the girl herself). We can write this as
b = 2(g-1)
Next,
we know that each boy has the same amount of brothers as sisters. Therefore, the amount of boys in the family minus 1 (b-1, subtracting 1 because we don't include the boy that has the brothers) is equal to the amount of girls in the family (g). we can write this as
b-1 = g
Therefore, we have
b = 2(g-1)
b-1 = g
Plugging b-1 = g into the first equation, we get
b = 2 (g-1)
2(g-1) = 2((b-1) - 1) = b
= 2(b-1-1)
= 2(b-2)
= 2b-4
b = 2b-4
subtract 2b from both sides to make it so that only b values and their coefficients are on one side
-b = -4
multiply both sides by -1 to solve for b
b=4
Therefore, there are 4 boys in the family and b-1 = 4-1 = 3 girls in the family.
y+196355 equals y+196355 or 196355y
but most likey it just stays the same
Answer:
(C
) b(x)=4(x+2)(x−2)
Step-by-step explanation:
We are given
The number of blue tiles in her design is modeled by the function b(x)=
if the no of blue tiles used is zero then
b(x) = = 0
= 4
x = +2 and -2
this is the condition for blue tiles
Modelling
b(x) = 4(x+2)(x-2)
This means when the blue tiles used are zero, then we use 2 red tile on each of the two square of 4 square. so the length will be 4 tiles long and its a square so 4x4 = 16 red tiles.
Answer:
3
Step-by-step explanation:
The dark point at x = 2 represents f(2). In this case, the limit is 3
