Find the solution set (x,y,z) of the system:<br> 3x-2y+4z=6<br> 2y-3z=20<br> 6z=12
gizmo_the_mogwai [7]

Answer:

The solution is x = 8, y = 13 and z = 2.

Step-by-step explanation:

We are given a system of equations with the variables x, y, and z from which we have to solve for x, y, and z.

The equations are

3x - 2y + 4z = 6 ........ (1)

2y - 3z = 20 .......... (2)

6z = 12 ......... (3)

Now, from equation (3),  we get z = 2.

Now, putting z = 2 in equation (2) we get

2y = 20 + 6 = 26  

⇒ y = 13

Now, from equation (1), putting y = 13 and z = 2, we get  

3x = 6 - (4 × 2) + (2 × 13) = 24

⇒ x = 8

So the solution is x = 8, y = 13 and z = 2. (Answer)

What is the standard form of a line?
shutvik [7]
It’s pretty much a special way of writing an equation of a line. it’s another way of writing y=mx+b. it’s Ax+By=C where a b and c are all real numbers and a and b are both not 0.the requirements can depend on what your doing but technically they are real numbers they are most often used as integers and to keep the a positive.also a b and c are usually required to not share common factors

The lifetime of a battery has the exponential distribution with mean 6.9 months. If it fails, I immediately replace it with anot
irga5000 [103]

Answer:

You should <u>carry 2 other batteries.</u>

Step-by-step explanation:

If the average life of each battery tends to last 6.9 months, and what you need is a year of battery supply, you probably need to carry two batteries.

The battery inside the flashlight has probably already spent much of its half-life.

We are told that the flashlight already has a battery inside, the batteries are discharged inside the flashlight even if the flashlight is not being used.

Which means that the average life of that battery is wearing out.

It would take 2 more batteries in addition to the one already inside the flashlight to supply the need for these for a year.
