What is the solution to the system of equations for y= -2x - 4 and y= 2x + 4
2 answers:
Y = -2x - 4 y = 2x +4 add the two equation 2y = 0 , y =0 2x + 4 = 0 2x = -4 x = -2
Y = -2x - 4 y = 2x + 4 substitute the first equation into the second equation to find x; -2x - 4 = 2x + 4 -4 = 2x + 4 + 2x -4 = 4x + 4 -4 - 4 = 4x -8 = 4x -2 = x solve for y given the value of x into the first equation; y = -2x - 4 y = -2(-2) - 4 y = 0 the answer is; x = -2, y = 0 or (-2, 0) hope this helps, God bless!

Step-by-step explanation:
(-7)•8z = -56z
(-4)•(-7)=28
and
40•(-1.4)= -56z
40•0.7= 28
Length = 2W P= 2L + 2W 60 = 2(2W) + 2W 60= 4W +2W 60 = 6W 60/6W = 6W/6W w = 10 Length = 2(10) Length = 20 P= 2L + 2W 60= 2(20) + 2(10) 60= 40 +20 60 = 60
