Answer:
4x+5y= -12
subtract 4x from both sides
5y = -4x - 12
divide by 5
y = -4/5 x - 12/5
-2x+3y= -18
subtract -2x
3y= -2x - 18
divide by 3
y= -2/3x -6
Product means to multiply.
Simply
9*12= 108

Answer:
Step-by-step explanation:
This is an arithmetic progression.
difference d = (-8) - (-2) = (-8) + 2 = (-6).
nth term = a + (n-1)d

Answer:
C
Step-by-step explanation:
For the given intervals
( - ∞, - 5) ← use any value < - 5 but not - 5, the parenthesis ) indicates that x is less than - 5 but not equal to - 5
(- 5, - 1) ← - 4, - 3, - 2 can be used but not - 5 or - 1
(- 1, 4) ← 0, 1, 2, 3 can be used but not - 1 or 4
(4, ∞ ) ← use any value > 4 but not 4
Hence
3 can be used in (- 1, 4)
- 6 can be used in (- ∞, - 5)
zero can be used in (- 1, 4)
- 5 cannot be used in any of the given intervals
