Describe all solutions of the system below in parametric vector form.

x+y-z = 3
x-2y+z = 0

I'm not sure how to approach this as none of the answer choices are matching what I found after row reduction and solving in traditional format of writing a solution set in parametric vector form.

if this is really you s much. i only have 3 points left and i have 2 questions to ask

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

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.
