Answer:
cm scale
Step-by-step explanation:
it may help you to understand
No it cant be because a number with a repeating decimal is irrational, rational numbers are integers that can be expressed as a fraction<span />
-x + y = 4
2x + y = 1
-3x = 3
-3 -3
x = -1
2x + y = 1
2(-1) + y = 1
-2 + y = 1
+ 2 + 2
y = 3
(x, y) = (-1,3)
Answer:
B
Step-by-step explanation:
Given
- 3x + 12 ≤ 15 ( subtract 12 from both sides )
- 3x ≤ 3
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x ≥ - 1
Since x can equal - 1, we are looking for a solid circle at x = - 1 on the number line.
Since x greater than - 1 we require the shaded arrow to be pointing right.
Graph B represents this
