I NEED HELP Are the two functions inverses? f ( x ) = − 8 x + 5 g ( x ) = − 1 8 x + 5 8 Group of answer choices Yes No

No

Step-by-step explanation:

To know if the functions are inverses of each other, it is easiest to just find the inverse of one of the functions. To find the inverse, you want to replace y with x and x with y and solve for y.

y=-8x+5                                  [switch x with y and y with x]

x=-8y+5                                  [subtract both sides by 5]

x-5=-8y                                   [divide both sides by -8]

y=(x-5)/-8

f⁻¹(x)=(x-5)/-8

Since we know that the inverse doesn't match g(x), we know that these functions are not inverses of each other.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
