<span>Lets assume number of daughters = x
and number of sons = y
each daughter has as many sisters as brothers so,
y = x - 1
x - y = 1 ----------- (1)
each son has 3 times as many sisters as brothers so,
x =3(y - 1)
x = 3y - 3
x - 3y = -3 ---------------(2)
Subtract (2) from (1),
-y + 3y = 1 - (-3)
2y = 4
y = 4/2 = 2
From (1),
x - y = 1
x - 2 = 1
x = 1 + 2 = 3
Daughters = x = 3
Sons = y = 2
Total children = 2 + 3 = 5</span>

Answer:
An equation in slope-intercept form of the line will be
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where m is the slope and b is the y-intercept
Given the points
Finding the slope between (-1,-1) and (1,0)
substituting m = 1/2 and (-1, -1) in the slope-intercept form of the line equation to determine the y-intercept
Add 1/2 to both sides
substituting m = 1/2 and b = -1/2 in the slope-intercept form of the line equation
Therefore, an equation in slope-intercept form of the line will be
Answer: A is the answer
Step-by-step explanation:
In general, complex numbers are treated specially because they are the a squared number that is equal to a negative number. This isn't possible in traditional math because a positive times a positive and a negative times a negative both produce a positive.
This property is true.
This property is also true.
We also know that
. The problem comes when you mix these two properties together. Lets solve each one practically and see what happens.
This is straight forward, plug and chug:
This one takes some more work, but still comes out to a simple answer.
The problem is we have two different answers for the same definition. This contradiction is why complex number notation was created.
is how
is written typically with the 6 part being the six from the radical and the i being
.
From this, we can multiply
and
to find the answer to your question.
