Answer:
3x+8=68 degrees
6x-8= 112 degrees
Step-by-step explanation:
3x+8+6x-8=180
9x=180
x=20
3*20+8=68
6*20-8=112
Answer:
1:2
Step-by-step explanation:
Given:
The boundary line of an inequality is:

The solution set contains (0,0).
To find:
The inequality.
Solution:
The boundary line of an inequality is

Since (0,0) is in the solution set, therefore (0,0) satisfies the required inequality.
Taking LHS, we get

Substitute x=0 and y=0.



The right hand side of the given equation is 6.

We know that,



The boundary line is not a dotted line, it means the points on the boundary line are also included in the solution set. So, the inequality sign must be
.

Therefore, the required inequality is
.
