Find the equation of the line parallel to y=4x-10 containing (5,-6)
kogti [31]
Y=mx+b, m=slope, b=y intercept

a line that is paralell will have the same slope with a different y intercept
y=4x-10
therefor the new equation is y=4x+b
subsitute
(x,y)
(5,-6)
x=5
y=-6
is on e solution so subsitue
-6=4(5)+b
-6=20+b
subtract 20
-26=b
the equation si y=4x-26

Each of my daughters has as many brothers as sisters, but each of my sons has three times as many sisters as brothers. How many
melomori [17]
Put the number of daughters as x and number of sons as y.

For the first half of the statement:
Number of sisters any daughter has = x-1 ( because you can't be your own sibling)
Number of brothers = y

y=x-1.

For the second half:
Number of sisters any son has = x
Number of brothers any son has = y-1

3(y-1)=x

Solve as system of equations.
3y-3=x
3(x-1)-3=x
3x-3-3=x
2x=6
x=3
y=x-1=3-1=2

3 daughters and 2 sons.

Hope this helps!
