the number a is smaller than the number b by 1/5 of b . by what part of a is b bigger than a?

Bigger by ¼ of a.

Step-by-step explanation:

Let b be represented by all five slices of the pie, and a by the four yellow slices.

Then a is ⅘ of the pie and it is ⅕ smaller than b.

Now, let's turn the argument around.

The four yellow slices represent a, and all 5 slices represent b.

b is greater than a by one slice compared to four.

In mathematical terms, b is bigger by ¼ of a.

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. : )
