Y = x + 5
y = -5x -1
so than you make y = y so x + 5 = -5x -1 result 6x = -6 so x = -6/6 so x = -1
and than you check it
y = - 1 +5 = 4
and
y = - 5 *(-1) -1 = 5 -1 = 4
so this mean that - 1 is the solution of the system sure
Answer:
(7, 0) The pool will be Empty
Step-by-step explanation:
It's leaking 5 liter each minute, by the time it gets to 7 minutes, it'll be empty
I think
So one way we can do this is-
2(2n+7)+3n=
4n+14+3n=
7n+14
Another simpler way possible is-
2n+7+2n+7+3n=
RE-ORDER
2n+2n+3n+7+7=
COMBINE LIKE TERMS
7n+14
Answer:
y=50°
x=232°
Step-by-step explanation:
cuz y+130=180
y=50
and
y+68+x=360°
50+68+x=360°
so x =232
The answer to this question is true
