Find the difference. Express the answer in scientific notation. (9.1 × 10–6) – (8.9 × 10–6)

2.0 × 10–7
0.2 × 10–6
2.0 × 10–6
2.0 × 10–5

it’s A / 2.0 x 10^-7

Step-by-step explanation:

THIS IS THE ANSWER ON EDU

i know because i just took it

eww xbox also eww dayz

step-by-step explanation:

just for that im not answering

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
