Step-by-step explanation:
I Think Its C
We're going to solve each of the systems to determine the solution.
<u>System </u>
using a graph tool
the solution is the line
see the attached figure N
<u>System </u>
using a graph tool
the solution is the shaded area
see the attached figure N
<u>System </u>
using a graph tool
The system has no solution
see the attached figure N
<u>System </u>
using a graph tool
the solution is the shaded area
see the attached figure N
therefore
<u>the answer is</u>
<u>System </u>
B . A & b are parallel to each other
I think what your asking for is that x=10
Answer:
Option B is correct
Step-by-step explanation:
Given that:
and are supplementary.
prove that:
It is given that:
and are supplementary.
By definition of supplementary
⇒ .....[1]
From the figure, you can see that:
and are also supplementary.
⇒ .....[2]
By [1] and [2] we have;
⇒
Simplify:
Since ∠2 and ∠3 are corresponding angles.
Corresponding angles states when the two lines are parallel, then Corresponding Angles are equal and vice versa.
by definition we have;
proved!
