This is a terrible question, LOL.

I would say 9 classes. 5 or 6 classes only = 5 or 6 hours. The least number of classes they need to take is 7, but that’s not an option, so I would go with 9.

What is the next two term in the sequence 6, 10, 14, 16
8090 [49]

Answer:

  • Next two terms of the sequence is 20 and 24.

Step-by-step explanation:

The arithmetic sequence is 6, 10, 14 , 16

First term (a) = 6

Subtract the first term from the second term:

  • 10 - 6 = 4

Subtract the second term form the third term:

  • 14 - 10 = 4

Subtract the third term from the Fourth term:

  • 16 - 14 = 4

Here, You will notice that each time you move from one number to the next one it increases by four. So, the difference between one and the next term is four.

So,

Next two terms are:

⟶ 16 + 4 = 20

⟶ 20 + 4 = 24

Hence,

  • <u>Next two terms of the sequence is 20 and 24.</u>

Solve the system of equations by graphing. x+y=-9 4x+y=-19
shutvik [7]

For this case we have the following system of equations:

x + y = -9\\4x + y = -19

We multiply the first equation by -4:

-4x-4y = 36

We have the following equivalent system of equations:

-4x-4y = 36\\4x + y = -19

We add the equations:

-4x + 4x-4y + y = 36-19\\-3y = 17\\y = - \frac {17} {3}

We find the value of the variable "x":

x = -9-yx = -9 - (- \frac {17} {3})\\x = -9 + \frac {17} {3}\\x = \frac {-27 + 17} {3}\\x = - \frac {10} {3}

Thus, the solution of the system is:

(x, y): (- \frac {10} {3}, - \frac {17} {3})

See the graphic in the attached image

ANswer:

(x, y): (- \frac {10} {3}, - \frac {17} {3})
