Answer:
x= -6
Step-by-step explanation:
equation: -10 - 2x = 2x + 14
subtract 14 from both sides: -24 - 2x = 2x
add 2x to both sides: -24 = 4x
divide both sides by 4: -6 = x
4 x 5/7 = 20/7
20/7 = 2 6/7
Answer:
(1,2) and (2,-1)
Step-by-step explanation:
we have
----> inequality A
The solution of the inequality A is the shaded area below the dashed line 
---->inequality B
The solution of the inequality B is the shaded area above the dashed line 
The solution of the system of inequalities is the triangular shaded area between the two dashed lines
If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area
Two points in the solution are(1,2) and (2,-1)see the attached figure
Counting numbers are whole integers starting from 1 and going to infinity. It doesn't include negative numbers or zero.
Therefore, the set would be:
{1, 2, 3, 4, 5, 6, 7, 8, 9}
