Answer:
A. y = -16
Step-by-step explanation:
Hello!
What we do to one side of the equation we have to do to the other.
y + 7 = -9
We have to get y by itself so we have to get rid of the seven by doing the opposite of what it says
The opposite of addition is subtraction so we subtract 7 from both sides
y + 7 - 7 = -9 - 7
Solve
y + 0 = -16
Simplify
y = -16
The answer is A. y = -16
Hope this helps!
Y = mx + c therefore
m = 1
c = -2
The slope of the line passing through (1,-5) and (4,1) is 2
Answer:
x + y + z = 272 - - - - - - (1)
x = 3y - - - - - - - - - - - - - (2)
z = 32 + y - - - - - - - - - - (3)
Step-by-step explanation:
Let :
Number of pop songs = x
Number of rock songs = y
Number of hophops = z
Sum of the three types of songs = 272
x + y + z = 272 - - - - - - (1)
Pop is 3 times Rock :
x = 3y - - - - - - - - - - - - - (2)
Hiphop is 31 more than rock
z = 32 + y - - - - - - - - - - (3)
