Answer:

12 \leq v

Step-by-step explanation:

first you subtract 7 from 7 and 12

19\leq v+ 7\\-7           -7

then you get 19 \leq v

(btw the variable always goes first with these problems)

so the final answer would be v \geq 12

7x−4≥−15+2x solve in interval notation
Leviafan [203]

Answer:

[-11/5,∞)

Step-by-step explanation:

1. Add 4 to both sides: 7x-4+4≥-15+2x+4

2. Simplify: 7x≥2x-11

3. Subtract 2x from both sides: 7x-2x≥2x-11-2x

4. Simplify: 5x≥-11

5. Divide both sides by 5: 5x/5≥-11/5

6. Simplify: -11/5
