The gradient of the function is constant s the independent variable (x) varies The graph passes through the origin. That is to say when x = 0, y = 0. Clearly A and D pass through the origin, and the gradient is constant because they are linear functions, so they are direct variations. The graph of 1/x does not have a constant gradient, so any stretch of this graph (to y = k/x for some constant k) will similarly not be direct variation. Indeed there is a special name for this function, inverse proportion/variation. It appears both B and C are inverse proportion, however if I interpret B as y = (2/5)x instead, it is actually linear. I believe the answer is C. Hope I helped!
-2x+2y=6
7x-8y=-27
5x-6y=-21
-x+y=3
6x-7y=-24
6x-7y=-4(-2x+2y)
6x-7y=8x-8y
-6x from both sides:
-7y=2x-8y
add 8y to both sides:
y=2x
-2x+2y=6
2y-6=2x
2y-6=-12
-6-6=-12
y=-3
x=-6
Hope this helps :)
Answer:P(N|V) = 0.62
P(N)=0.59
Not independent

Answer:
The bill returns to the house of origin.
If the bill advances with amendments, it returns to the house of origin. The house of origin may fail to take action, and the bill “dies.” The legislative body may vote to approve the changes made by the second chamber.
Step-by-step explanation:
She had 2 rows. Because 4+2 is 6 and 6 tomatoes so thats 12 in total so if you divide 2 into 12 and that will give you 2.
