A. NOT
(-5, 2) → x = -5, y = 2
y ≤ x - 5 → 2 ≤ -5 - 5 → 2 ≤ -10 FALSE
B. YES
(5, -2) → x = 5, y = -2
y ≤ x - 5 → -2 ≤ 5 - 5 → -2 ≤ 0 TRUE
y ≥ -x - 4 → -2 ≥ -5 - 4 → -2 ≥ -9 TRUE
C. NOT
(-5, -2) → x = -5, y = -2
y ≤ x - 5 → -2 ≤ -5 - 5 → -2 ≤ -10 FALSE
D. NOT
(5, 2) → x = 5, y = 2
y ≤ x - 5 → 2 ≤ 5 - 5 → 2 ≤ 0 FALSE
Answer:
n = (123 - 3a) / 0.1
Step-by-step explanation:
Given:
3a + 0.1n = 123
Solve for n
3a + 0.1n = 123
Subtract 3a from both sides
3a + 0.1n - 3a = 123 - 3a
0.1n = 123 - 3a
Divide both sides by 0.1
n = (123 - 3a) / 0.1
The resulting equation if 3a + 0.1n = 123 is solved for n is n = (123 - 3a) / 0.1
My guess would be probably the first one !
