(-3x+3y=-9)-(-3x+y=7)
-3x+3x+3y-y=-9-7
2y=-16
y=-8, making -3x+3y=-9 become:
-3x+3(-8)=-9
-3x-24=-9
-3x=15
x=-5
So the solution to this system of equations is the point (-5, -8)
25 days
First, start with an equation
100+8x= kittens weight
(X representing the days)
Since you’re trying to figure out the number of days it takes the kitten to triple it’s weigh you multiply it’s initial weight by 3 (100•3)
Then, you output 300 into the equation and solve
Answer:
From five given points it is find that points (1 , 1) and (4 , -1) will apply
Step-by-step explanation:
According to question,
Slop of line (m) = 
And y-intercept is ( 0,
)
So from above slope and points, the equation of line can be written as
y = mx + c
i.e
=
x + c
=
(0) + c
= 0 + c
Or, c = 
A) With points ( 5,
)
At x = 5, y =
(5) + 
or, y =
+
so, y = 
Hence this points do not apply
B) With points ( 1 , 1 )
At x = 1, y =
(1) + 
or, y = 
So, y = 
y = 1
Hence this points will apply
C) With points ( 4 , -1 )
At x = 4 , y =
(4) + 
y = 
y = 
So, y= -1
Hence this points will apply
D) With points (-3 ,7)
At x = - 3, y =
(-3) + 
y =
Hence this point will not apply
E) with points (0 , 0)
At x 0, y =
(0) + 
Or, y = 0 + 
y = 
Hence this point will not apply
∴ From above five given points it is find that points (1 , 1) and (4 , -1) apply
