When verifying that a function represented in another table is the inverse of the given cost function, which ordered pair can be expected?

(20, 20)
(52, 20)
(20, 52)
(52, 52)

Option B is correct.

Step-by-step explanation:

To find the inverse of the function, the ordered pairs are inverted. i.e. x becomes y and y becomes x.

So, We are given in the table:

(20,52) ,(25,67.5), (30,84)

The inverse would be:

(52,20), (67.5,25),(84,30)

So, Option B is correct.

in 4 days he will run   12/14

step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
