Answer:
x = 0, y = -3
Step-by-step explanation:
plug in x as y + 3 into the first equation
6(y+3) - 5y = 15
6y+18 - 5y = 15
y = -3
x= 0
Answer:
Step-by-step explanation:
I take it you want x = 3
y = abs(3 - 3) + abs(3 + 2) - abs(3 - 5)
y = 0 + 5 - abs(-2)
y = 0 + 5 - (2)
y = 0 + 5 - 2
y = 3
If you meant something else please leave a note.
Now all you do is redo the problem for 5
y = abs(5 - 3) + abs(5 + 2) - abs(5 - 5)
y = abs(2) + abs(7) - abs(0)
y = 2 + 7 - 0
y = 9
Now set up your inequality
3 < y < 9
Answer:
see explanation
Step-by-step explanation:
If (x + 2) is a factor then x = - 2 is a root and p(- 2) = 0
p(- 2) = -4
+ 6(- 2)³ + 8(- 2)² + 2(- 2) - 1
= - 64 - 48 + 32 - 4 - 1 = - 85
Hence remainder R = - 85
Since p(- 2) ≠ 0 then (x + 2) is not a factor of p(x)
-12 is the correct answer
