x-2y = -2
x-2(-3x+8)=-2
mutiply the bracket by -2
(-2)(-3x)=6x
(-2)(8)=-16
x+6x-16=-2
7x-16=-2
move -16 to the other side
sign changes from -16 to +16
7x-16+16=-2+16
7x= -2+16
7x= 14
divide both sides by 7
7x/7=14/7
x=2
Find y by using the substitution method
y=-3x+8
y=-3(2)+8
-6+8
=2

Answer:
- maximum current: 7
- time to reach maximum: 1
Step-by-step explanation:
The equation can be rewritten to vertex form to find the maximum value:
I = -5(t^2 -2t) +2 . . . . . . factor leading coefficient from variable terms
I = -5(t^2 -2t +1) +2 -(-5(1)) . . . . . add and subtract the square of half the t coefficient
I = -5(t -1)^2 +7 . . . . . . write in vertex form
The vertex of the graph is at (t, I) = (1, 7).
The maximum current of 7 is reached at t=1.
