Which expression is equivalent to 3^4 ⋅ 3−^9?

3^-5 = 1/3^5

Step-by-step explanation:

3^4 ⋅ 3−^9

When multiplying exponents and the bases are the same, we can add the exponents

a^b * a^c = a^ ( b+c)

3^4 ⋅ 3−^9

3^( 4-9)

3^-5

We know that a^ -b = 1/a^b

3^-5 = 1/3^5

step-by-step explanation:

options

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. : )
