Which classification describes the following system of equations? inconsistent and dependent consistent and dependent consistent
sveta [45]

The system of equations is consistent and independent and the solutions are x = 4, y = 5, and z = -1 option third is correct.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have three linear equations in three variables:

x - y - z = 0 ..(1)

2x - y + 2z = 1 ..(2)

x - y + z = -2 ..(3)

From the equation (1):

\rm x=y+z

Plug this value in the equation (2) and (3):

\rm 2\left(y+z\right)-y+2z=1\\\\ y+z-y+z=-2

After solving we get:

z = -1

y = 5

Plug the above two values in equation (1) we get:

x = 4

Thus, the system of equations is consistent and independent and the solutions are x = 4, y = 5, and z = -1 option third is correct.

Planet Fitness charges a one-time application fee of $50 plus $30 per session for a
Vsevolod [243]

Answer:

When the number of sessions is equal to 10, the total cost is the same in the two plans

Step-by-step explanation:

Let

y ---> the total cost

x ---> the number of sessions

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

Planet Fitness

we have

The slope is equal to

m=\$30\ per\ session

The y-intercept or initial value is equal to

b=\$50

substitute

y=30x+50 ----> equation A

Gold's Gym

we have

The slope is equal to

m=\$10\ per\ session

The y-intercept or initial value is equal to

b=\$250

substitute

y=10x+250 ----> equation B

Equate equation A and equation B

30x+50=10x+250

solve for x

30x-10x=250-50\\20x=200\\x=10

therefore

When the number of sessions is equal to 10, the total cost is the same in the two plans

Answer this question please.
JulijaS [17]

Answer:

56

Step-by-step explanation:

The probability both spiners land on red: 0,5*0,6=0,3 (0,5 is A spine lands on red and 0,6 is B spiner lands on red)

The number of both spiners land on red is 84.

So we have:

X——>100%

84——->30%

X=8400/30

X=280

The total number of all spines A and B for onse.

The probability to both spiners land on blue is:

0,5*0,4=0,2 (0,5 is probabiliti to A lands on blue, 0,4 is B lands on blue)

The number of both spiners land on blue is:

280*0,2=56
