You can use a plot diagram to plot the points and if they all go straight through the origin then it is proportional
Equate the real and imaginary parts independently to find x and y.
Real part: -4=x, so x=-4
Imag. part yi=3i, so y=3
2x(y-z)+x(y+z)
2xy-2xz+xy+xz
like terms.(2xy+xy=3xy)(-2xz+xz=-xz)
=3xy-xz
Answer:
see explanation
Step-by-step explanation:
The statements tells us that w is inversely proportional to v and the equation relating them is
v = 
← k is the constant of proportion
To find k use the condition v = 9, w = 5, that is
9 = 
( multiply both sides by 5 )
45 = k
v = 
← equation of proportion
When w = 4 , then
v = 
= 11.25
Answer:
0
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
= (16-16)/(9--14)
= (16-16)/(9+14)
=0/23
The slope is zero which means this is a vertical line. The y value does not change
