Parallel lines would have to have the same slope so the green line also has a 1/5 slope
Answer:
y = 9
Step-by-step explanation:
When the line crosses y-axix, x-co ordinate = 0
y = -4*0 + 9
y = 0 + 9
y = 9
Step-by-step explanation:
4x+9y=28
-4x-y=-28
8y=0
divide both side by 8
y=0
solve for X in equation 1
4(X)-9(0)=28
4x-0=28
4x =28
divide both side by 4
4x/4=28/4
X= 7
y=0,x=7
Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the figure ABCD
Remember that the sum of the internal angles in a quadrilateral is equal to
so
-----> complementary angles
and
-------> complementary angles too
so
