I watch Khan Academy and in this video(https://www. khanacademy. org/math/pre-algebra/pre-algebra-ex ponents-radicals/pre-algebra-comput ing-scientific-notation/v/scientifi c-notation-example-2?modal=1) Sal said Scientific Notation have to be a * 10^n, and a have to be larger or same as 1, and It has to be less than 10. Then, Is 0.0036 x 10^4 is scientific notation?

step-by-step explanation:

jbjuiuhuhuuy

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. : )

there are infinitely many solutions.
