Answer:

The correct option is 1. The value -3 is NOT in the domain of the piecewise function.

Step-by-step explanation:

Domain is the set of input for which the function is defined.

From the given graph it is notice that the given piecewise function is not defined for x=-3 because there are open circles on the each piece of function at x=-3.

From the left curve it is clear that the function is defined for all x<-3.

From the right curve it is clear that the function is defined for all x>-3.

Domain of the given function is

Domain=\{x|x\in R, x\neq -3\}

The domain of the function is all real number except -3.

Since the value -3 is NOT in the domain of the piecewise function, therefore the correct option is 1.

During their last game, the Miami Dolphins scored ͸ times for a total score of ͵Ͳ points. They scored ͹ points for each touchdow
Karolina [17]

Answer:

The Miami Dolphins had 3 touchdowns and 3 field goals.

Step-by-step explanation:

It is given that During their last game, the Miami Dolphins scored 6 times, for a total score of 30 points. They scored 7 points for each touchdown and 3 points for each field goal.

We need to write and solve the system of equations to find the total touchdowns and field goals scored.

Let x represents the number of touchdowns.

Let y be the number of field goals.

It is given that the Miami Dolphins scored 6 times

x+y=6

x=6-y....(1)

They scored 7 points for each touchdown and 3 points for each field goal.

The total score is 30 points:

7x+3y=30 ...(2)

Put the value of x from equation (1) into equation (2).

7( 6-y)+3y=30

42-7y+3y=30

-4y=30-42

-4y=-12

y=3

Put y = 3 in equation 1.

x=6-3

x=3

Hence, the Miami Dolphins had 3 touchdowns and 3 field goals.

6925

*   33

______

Step 2:

5*3=15

carry the one

3*2+1=7

9*3=27

carry the 2

SO your first number is 20775 but we are NOT done yet!

add a zero below 5

5*3=15

carry the one

3*2+1=7

9*3=27 carry the 2

then 6*3+2=20

then add 207750+20775
