PLEASE HELP!
Which of the following functions are the inverse of p(x)= √5x+7 ?

B

Step-by-step explanation:

You are given the function

p(x) = √5x+7

Let p(x) = y then,

Y = √5x+7

To find the inverse of a function, you need to interchange x and y and make y the subject of formula. That is,

X = √5y+7

Square both sides

X^2 = 5y + 7

Make y the subject of formula

5y = x^2 - 7

Y = ( x^2 - 7 ) / 5

the correct answer is B

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

a .4y4

hope this !
