There are 256 possible combinations of fireworks, if they can be repeated in each 4 firework combinations.
If they cannot be repeated, there are 24 possible combinations.
X+2y = 9 ---------eq.1
x-y =6 ----------- eq.2
x = 9 -2y (from eq. 1)
Now substitute the value of x in the second eq.2
9-2y-y =6
-3y = -3
y =1
So,
x +2 (1)= 9
x= 7

Answer:
y = 20 + 40x
Step-by-step explanation:
You can see that where x = 0, y = 20, which gives us the y intercept. We can also see that for each step on the grid, x increases by 0.5, and y increases by 20. Which means that y increases at a rate of 20/0.5 - or 40 - with respect to x.
