Answer:
Step-by-step explanation:
let x be apple juice and y be orange juice
12 = x + y
x = 12 - y
15 = 1x + 1.5y
x = 15 - 1.5y
set the equations as equal
12 - y = 15 - 1.5y
solve for y
12 + .5y = 15
.5y = 3
y = 6, you bought 6 bottles of orange juice
so, 12 = x + 6 , x = 6 , you bought 6 bottles of apple juice
Answer:

Step-by-step explanation:
Given differential equation,


Let y = vx
Differentiating with respect to x,

From equation (1),








Integrating both sides,




Now, y = vx ⇒ v = y/x

- 10, you go down 4 - this is shown because to get from two to 10 in two, you have to go 2+4=6+4=10
