How does the decimal point move when 0.45 is multiplied by 10 to the 4 power.

450,000.

Step-by-step explanation:

The decimal point moves to the right, because 10 to the power of 4 is 10,000.

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. : )
