If d varies directly as t and d = 20.5 when t=12 find: (a) the value of the constant
(b) the relationship between d and t
(c) the value of d when t =6.​

B or c but im sure its B

Step-by-step explanation:

just did this answer!

answer: the answer is 23

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
