Answer:
NO SOLUTION
Step-by-step explanation:
Let's actually solve the system
x-4y=1
5x-20y=4
Let's eliminate y. To do this, multiply the first equation by -5, obtaining
-5x + 20y = -5
Now add this result to the second equation:
-5x + 20y = -5
5x - 20y = 4
--------------------
0 = -1
This result is never true. Thus, this system of linear equations has NO SOLUTION.
Answer:
B
Step-by-step explanation:
This is because when you reflect a triangle the letters need to be the same distance from the point of reflection (the y axis) when you count everything out B is the only answer with all of the correct coordinates.
original coordinates are
A (0,3)
B(-1,1)
C(2,1)
so add 3 to the x's and subtract 3 from the y's
A becomes (3,0)
B becomes (2,-2)
C becomes (5, -2)
6.3 = 0.9y
y would equal 7
1+4=5
2+5=7
5+7=12
3+6=9
12+9=21
I do not see21 up here so please cheek your question again or please change the 19 to a 21
