if f(x) = 6x – 4, what is f(x) when x = 8? 2164452

f(8) = 44.

Step-by-step explanation:

Given  : f(x) = 6x – 4.

To find :  what is f(x) when x = 8

Solution : We have given that

f(x) = 6x – 4.

For x = 8 we need to find f(8)

f (8) = 6 (8) -4 .

f(8)  = 48 - 4 .

f(8) = 44.

Therefore, f(8) = 44.

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.

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
