im gonna be honest they all look the same but im gonna go B a pair of marbles the same color, im sorry if im wrong :(
Step-by-step explanation:
Answer: the system of linear equations has no solutions.
Step-by-step explanation:
The given system of linear equations is expressed as
2x -3y =1 - - - - - - - - - - - - -1
-4x+6y=-4 - - - - - - - - - - - - - 2
We would eliminate x by multiplying equation 1 by 2 and equation 2 by 1. It becomes
4x - 6y = 2
- 4x + 6y = - 4
Adding both equations, it becomes
4x - 4x - 6x + 6x = 2 - 4
0 = -2
Therefore, there is no solution to the system of linear equations
Answer:
a) 10 = X + Y
b) X = 1, Y = 9
X = 2, Y = 8
X = 3, Y = 7
X = 4, Y = 6
X = 5, Y = 5
i) The inputted values of X and Y are the solutions of the equation because they sum up to the 10 songs on Nyla's playlist.
Step-by-step explanation:
The given parameters are;
The number of songs in the playlist on her phone = 10
The number of authors of the songs on her playlist = 2
The equation that represent the situation is given as follows;
X + Y = 10
Where X represent the number of Beyonce's song on her playlist and Y represent the number of Jennifer Lopez's song on her playlist
b) 5 possible solutions are;
X = 1, Y = 9
X + Y = 1 + 9 = 10
Which gives 1 Beyonce's and 9 Jennifer Lopez's songs
X = 2, Y = 8
X + Y = 2 + 8 = 10
Which gives 2 Beyonce's and 8 Jennifer Lopez's songs
X = 3, Y = 7
X + Y = 3 + 7 = 10
Which gives 3 Beyonce's and 7 Jennifer Lopez's songs
X = 4, Y = 6
X + Y = 4 + 6 = 10
Which gives 4 Beyonce's and 6 Jennifer Lopez's songs
X = 5, Y = 5
X + Y = 5 + 5 = 10
Which gives 5 Beyonce's and 5 Jennifer Lopez's songs
i) The inputted values of X and Y are the solutions of the equation because they sum up to the 10 songs on Nyla's playlist.
Answer: The slope is 2.
Step-by-step explanation:
To get the slope, use this tip: Rise over run
Count how much it rises, which is 4, and how much it "runs' which is 2. Now put rise above run which is 4/2. This simplifies to simply 2.
First you take away 15 from 20 to get just one number on each side of the equal sign then you add those two so 3(15)=20 would end up being 15
