Answer:

Step-by-step explanation:

Hi, remember that when we have an equation the important thing is to know the value of the unknown value, in this case is "x"

So the best answer to this is B

because when you substract -4 in both sides of the equation you obtain $x+4-4=15-4$

$x=15-4$

D could also be right but there´s no sense in that equation because as I told you we want to know the value of the unknown , and 4 is not an unknown value

Answer:

810

Step-by-step explanation:

450 × 1.80 = 810

The 1 represents how there is no markdown and the .80 is the 80% being marked up.

I think there is a more specific equation for this than the one I showed, but this was my way of solving these questions without giving myself a headache

Consider the tables that represent ordered pairs corresponding to a function and its inverse. When comparing the functions using

lara31 [8.8K]

Answer:

D)The range of f(x) includes values such that y ≥ 1, so the domain of f–1(x) includes values such that x ≥ 1.

Step-by-step explanation:

The missing tables are:

First table

x: 0 1 2

f(x): 1 10 100

Second table

x: 1000 100 10

f^-1(x): 3 2 1

Option A is not correct because f(x) has a y-intercept at (0, 1)

If f(x) has a y-intercept, then f^-1(x) has a x-intercept, which is located at (1, 0). Then option B is not correct

Option C is not correct because the domain of f^-1(x) is associated with x values.

Option D is correct because the domain of f(x) is the range of f^-1(x) and vice versa
