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:
x = 3 or x = 2 or x = -6
Step-by-step explanation:
Solve for x:
(x - 3) (x^2 + 4 x - 12) = 0
Split into two equations:
x - 3 = 0 or x^2 + 4 x - 12 = 0
Add 3 to both sides:
x = 3 or x^2 + 4 x - 12 = 0
The left hand side factors into a product with two terms:
x = 3 or (x - 2) (x + 6) = 0
Split into two equations:
x = 3 or x - 2 = 0 or x + 6 = 0
Add 2 to both sides:
x = 3 or x = 2 or x + 6 = 0
Subtract 6 from both sides:
Answer: x = 3 or x = 2 or x = -6
Answer: 23 - 6 = x
x = 17
Step-by-step explanation:
6 + x = 23
x = 23 - 6
23 - 6 = 17
x = 17
6 + 17 = 23
Hope this helps!
6 + 8 = 14.
You have 6, then just count up 8 times, and then you will get 14.
