Answer:
-0.4
Step-by-step explanation:
-9x+0.4=4
-0.4 -0.4
_______________
-9x=3.6
__ __
-9 -9
________________
x=-0.4
AM really good at this!!
a)
Subtract 0.4 from both side.
-9x +0.4 = 4
-9x + 0.4 - 0.4 = 4 - 0.4
-9x = 3.6
b)
divide by -9 both side
-9x/-9 = 3.6/-9
x = -0.4
c) x = - 0.4
This is all the above
all answers are true to this graph
think the answer is x=6+sqrt0/2 x=6-sqrt0/2 both equaling into 3.
But I might be wrong.
I dont know if this helps
