Answer:
B
Step-by-step explanation:
The answer is B because if a line goes through (0,0) then it is automatically proportional.
Step-by-step explanation:
let the no.s of apples in the one box be=x
then no.s of apples in the 2nd box =24-x
according to the question,
24-x+4=20
-x= 20-28
-x=-8
x= 8
no.s of apples in one box= 8
and no.s of apples in another box=24-8= 16

Answer:
x = -8/3
y = 4
Step-by-step explanation:
I assume you want to solve for x and y.
The best way to do this with the two formulas given is elimination. This means add the two equations together.
6x + 5y = 4
-6x + y = 20
The 6 x and -6x will cancel each other. By adding the like terms of the two together you will come out with
6y = 24
Now solve for y by dividing both sides by the 6.
y = 24/6 = 4
Now that we have y, you can plug it into one of the equations and solve for x.
Let's use -6x + y =20.
So plug in the 4 for y to get -6x + 4 = 20
Subtract the 4 from both sides then solve for y by dividing both sides by the -6.
-6x = 16
x = -16/6
You can reduce that down so that x = -8/3.
