Answer:
xy1
Step-by-step explanation:
Correct option is C)
Given two equations are 2x+y+4=0 and x=3y+7=0
let us consider 2 equations ax+by+c=0 and mx+ny+p=0
By cross multiplication method ,the equations obtained will be ,
b×p−n×c
x
=
c×m−a×p
y
=
a×n−b×m
1
Thus comparing it with given 2 equations we obtain:
7−12
x
=
4−14
y
=
6−1

Answer:
B
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
we know that the interior angles equal 180 and that the triangles are congruent so, 66 + 78 = 144 so then we have to subtract 180 - 144 and that gives us 36
Hope I helped :)
We can use the distributive property for this:
-5(3 - 6) = -45
-15 + 30 = -45
15 = -45.
Soooo that's like the farthest you can simplify... and both sides aren't equal...sooo yeah.
