Answer:
,
Step-by-step explanation:
we know that
In a parallelogram, opposite angles are congruent and consecutive angles are supplementary
so
----> equation A
-----> equation B
we have

substitute in the equation B and solve for m<R


-----> substitute in equation A
Answer:
k=5
Step-by-step explanation:
step 1
Find the equation of the line f(x)
we have the points
(-4,0) and (-2,2)
<em>Find the slope m</em>

Find the equation of the line in point slope form

we have

substitute


Remember that
f(x)=y
so

step 2
Find the equation of the line g(x)
we have the points
(-4,0) and (-2,-10)
<em>Find the slope m</em>

Find the equation of the line in point slope form

we have

substitute


Remember that
g(x)=y
so

Remember that
------> 
therefore
k=5
Answer:
C
Step-by-step explanation:
In negative smaller numbers are greater
Answer:
(2, -1)
Step-by-step explanation:
The lines intersect at (2,-1), I graphed out the equations
To find the area of a circle use the equation
A = πr^2
