Answer:

Solution of the system of equations

y = x + 3

x = –2 is:

(-2,1)

Step-by-step explanation:

We have to find the solution of the system of equations:

y = x + 3

x = –2

Solution means values of x and y

x= -2

Putting it in equation y=x+3

⇒ y= -2+3

⇒ y= 1

Hence, solution of the system of equations

y = x + 3

x = –2 is:

(-2,1)

kirill115 [55]

Answer:

There are 12 sets of four marbles include all the red ones.    

Step-by-step explanation:

Given : A bag contains three red marbles, two green ones, one lavender one, four yellows, and five orange marbles.

To find : How many sets of four marbles include all the red ones?

Solution :

Number of red marbles = 3

Number of green marbles = 2

Number of lavender marbles = 1

Number of yellow marbles = 4

Number of orange marbles = 5

We have to form sets of four marbles include all the red ones,

For position of getting red ones we have three red marbles i.e. ^3C_3

For the fourth one we have 12 choices i.e. ^{12}C_1

Total sets of four marbles include all the red ones is

=^3C_3\times ^{12}C_1

=1\times 12

=12

Therefore, There are 12 sets of four marbles include all the red ones.
