Substitute this equation y=2/3x-1 if y=3

I believe what your asking me to do is put the y value back into the equation and solve for x. If so x=6 or x=(5/9) SEE BELOW

Step-by-step explanation:

y=(2/3)x-1 , y=3

3=(2/3)x-1

4=(2/3)x

x=6

OR

y=2/(3x-1)

x=(5/9)

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
