Which expressions are equivalent to the one below? check all that apply.

A does not. You are getting something like 15^9/5, as an example, which is very much larger than 3^9. So A is wrong.

B is correct. (15/5)^x = 3^x Both 15 and 5 are inside the brackets.

C is correct. 3^1 * 3^(x - 1) = 3^(x - 1 + 1) = 3^x

D is correct (15^x)/5^x = (15/5)^x = 3^x

E is not correct. It is not a general case and the base number is 3 not x.

F is not correct. 3^1*3^(x + 1) = 3^(x + 2) not correct.

B C and D are correct. The rest are not.

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
