Answer:
A(-5,9)
Step-by-step explanation:
Let A(a,b)
Since M is the midpoint then of A(a,b) and B(3,-5) then
M( (a+3)/2 , (b-5)/2)
But it is given that M(-1,2)
So (a+3)/2 = -1 which implies a=-5
and (b-5)/2=2 which implies b=9.
Therefore A(-5,9)
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.
The average value is given by

1) Given: f(x) = 3 - x; g(x) = -2x Find g[f(-1)].
g(f(x)) = -2(3 - x) = 2x - 6
g(f(-1)) = 2(-1) - 6 = -2 -6 = -8
g(f(-1)) = -8
Looks like the question 2 and 1 are the same
Both find g(f(-1))
