Answer:
j= (-2,2)
k=(2,1)
Step-by-step explanation:
Answer:
0.0000007 as a regular notation
or 7x10^-7 as scientific notation
Given:
![-3x+2b>8](https://tex.z-dn.net/?f=-3x%2B2b%3E8)
To find:
The value of x.
Solution:
We have,
![-3x+2b>8](https://tex.z-dn.net/?f=-3x%2B2b%3E8)
To find the value of x, we need to isolate x on one side.
Subtract 2b from both sides.
![-3x>8-2b](https://tex.z-dn.net/?f=-3x%3E8-2b)
Divide both sides by -3. On multiplying or dividing an inequality by a negative number, we need to change the sign of inequality.
![\dfrac{-3x}{-3}](https://tex.z-dn.net/?f=%5Cdfrac%7B-3x%7D%7B-3%7D%3C%5Cdfrac%7B8-2b%7D%7B-3%7D)
![x](https://tex.z-dn.net/?f=x%3C%5Cdfrac%7B-2b%2B8%7D%7B-3%7D)
The required inequality for x is
.
Therefore, the correct option is A.
Answer:
A
Step-by-step explanation:
A is correct because if the minimum is 29,000 feet, x (the airplane altitutude) must be greater than or equal to 29,000 ft. Since the maximum is 41,000 feet, x must be less than or equal to that number.
