Answer:
D. x ≥ -13/2 or x < -41/6
Step-by-step explanation:
- 5/2+x ≥ 1/3 ⇒ x ≥ 1/3 -5/2 ⇒ x ≥ - 13/2
or
- x+2 < -29/6 ⇒ x < -29/6 - 2 ⇒ x < -41/6
So combined the answer is:
Option D is correct
Answer:
5677
Step-by-step explanation:
2100 +1477 = 3577
2100+3577= 5677
5x + y = 15
y = -5x + 15
Substituting y= -5x+15 from first equation into second equation:
3x + 2y = 16
3x + 2·(-5x + 15) = 16
3x - 10x + 30 = 16
-7x + 30 = 16
7x = 30 - 16 = 14
x = 2
Substituting x=2 into the first equation:
5x + y = 15
5(2) + y = 15
10 + y = 15
y = 15 - 10
y = 5
So your final answers are x=2 and y=5.
