Question

If f(x) varies directly with x, and f(x) = 8 when x = 6, write the direct linear variation equation.

Answer 1

f(x)=8+6

Answer 2

thanks

Answer 3

If f(x) varies directly with x, and f(x) = 48 when x = 8, find the value of f(x) when x = 2
how about this

Answer 4

42 because 40 +8 =48 or f(x)=40+8 so f(x)=40+2 or 42

Answer 5

thats not a option its 12 6 8 3

Answer 6

sorry its 12 8 times 6 is 48 and 6 times by 2 is 12

Answer 7

so its 12

Answer 8

yes

Answer 9

Which does NOT show a direct variation between x and y? y = 2x
y = 0.5x

Answer 10

or y= y/9 , y=x/9

Answer 11

y=y/9 because x is nonexistent

Answer 12

thanks so much

Answer 13

you are welcome!!

Answer 14

can you do this one please What is the domain of the function: {(1, 2); (2, 4); (3, 6); (4, 8)}

Answer 15

that one is one im not so sure ill be able to help you with! i learned that so long ago!
