Answer:
(x - 9)(x + 5)
Step-by-step explanation:
x² − 4x − 45 =
= x² + 5x - 9x - 45
= x(x + 5) - 9(x + 5)
= (x - 9)(x + 5)
Step-by-step explanation:
Y - 5 1/2 = 3 1/3
Y = 3 1/3 + 5 1/2
Y = 8.83
Answer:
x=20 and y=16
Step-by-step explanation:
4x - 6y= -16
since y=x -4, we substitute it in place of "y"
Then, 4x - 6(x-4) = -16
4x - 6x + 24 = -16
-2x+24= -16
-2x= -16-24
-2x= -40
Divide both sides by -2 then,
x=20
once we get the value of "x" we substitute in place of "y=x-4"
y=20-4
y=16
