Answer:

-5x+3 OR 5x-3

Step-by-step explanation:

You find the inverse by replacing the x with the y, and solving for y. Doing this actually gives you -5x+3 but in this case,  the closest answer would be 5x-3.

UPDATE: -5x + 3 can be written as 3 - 5x lol

Answer:

B. f⁻¹(x) = 3 - 5x

Step-by-step explanation:

f(x) = (3 - x)/5

Replace f(x) with y.

y = (3 - x)/5

Switch the variables.

x = (3 - y)/5

Multiply both sides by 5.

5x = 3 - y

Subtract 3 from both sides.

5x - 3 = -y

Multiply both sides by -1.

y = -5x + 3

Apply commutative property.

y = 3 - 5x

Replace y with f⁻¹(x).

f⁻¹(x) = 3 - 5x.

If P = (-2,-1) and Q = (4,3) are the
Ivanshal [37]

Answer:

Step-by-step explanation:

P(-2,-1) and Q(4,3)

average of x-coordinates = (-2+4)/2 = 1

average of y-coordinates = (-1+3)/2 = 1

midpoint of PQ: (1,1)

distance between midpoint and Q = √((4-1)²+(3-1)²) = √13

(x-1)² + (y-1)² = 13

3x+7=5x-21
schepotkina [342]
Just get only one of  the placeholder on one side by itself
and do the same thing to both sides so it stays equal
3x+7=5x-21
add 21 to both sides
3x+28=5x
subtract 3x from obht sides
28=2x
sivide both sides by 2
14=x
