Answer:
let cp of 17 water bottle is x
cp of 1 water bottle = x/17
from the question
sp of 16 water bottles = x
sp of 1 water bottle = x/16
profit = sp -cp
= x/16 - x/17
= x/272
profit % = profit /cp * 100%
= (x/272)/ (x/17) * 100%
= 6.25%
{ x + y = 1 * ( - 2 )
2 x + 3y = -4
- 2 x - 2 y = - 2
2 x + 3 y = - 4
_______________
y = - 6
Subsititute y = - 6
<span>
2 x + 3 y = - 4
2 x + 3 * (-6) = -4
2 x - 18 = - 4
2 x = - 4 + 18
2 x = 14
x = 14 / 2
x = 7
The solution to the system of equations are:
x = 7 and y = - 6
hope this helps!

That is actually true. Everything thats multiplied by 0 eaquals 0.
Answer:

Step-by-step explanation:

the function is only defined when (x+1) >= 0 (since square root) so the domain is when x >= -1
