10

Answer 9

The expression for the total number of players in the tournament can be written as 13b.

Answer 10

The expression for the number of cookies that remained can be written as b - 12.

Answer 11

The algebraic expression for "Twice b" would be 2b.

Answer 12

The algebraic expression for "x more than 5" would be x + 5.

Answer 13

To evaluate the expression a - 8y when a = 5 and y = -4, substitute the given values into the expression:

a - 8y = 5 - 8(-4)

Next, simplify the expression:

= 5 + 32

= 37

Therefore, when a = 5 and y = -4, the expression a - 8y evaluates to 37.

Answer 14

To evaluate the expression 6c - b when b = -5 and c = 7, substitute the given values into the expression:

6c - b = 6(7) - (-5)

Next, simplify the expression:

= 42 + 5

= 47

Therefore, when b = -5 and c = 7, the expression 6c - b evaluates to 47.

Answer 15

To fill in the table using the function rule y = 3x + 3, we substitute the given values of x into the equation and calculate the corresponding values of y.

For x = 2:
y = 3(2) + 3
y = 6 + 3
y = 9

For x = 7:
y = 3(7) + 3
y = 21 + 3
y = 24

For x = 8:
y = 3(8) + 3
y = 24 + 3
y = 27

For x = 9:
y = 3(9) + 3
y = 27 + 3
y = 30

The completed table is:

x y
2 9
7 24
8 27
9 30

Answer 16

To fill in the table using the function rule y = 22 - 4x, we substitute the given values of x into the equation and calculate the corresponding values of y.

For x = 1:
y = 22 - 4(1)
y = 22 - 4
y = 18

For x = 3:
y = 22 - 4(3)
y = 22 - 12
y = 10

For x = 4:
y = 22 - 4(4)
y = 22 - 16
y = 6

For x = 5:
y = 22 - 4(5)
y = 22 - 20
y = 2

The completed table is:

y x
18 1
10 3
6 4
2 5

Answer 17

To fill in the table using the function rule y = 3x - 4, we substitute the given values of x into the equation and calculate the corresponding values of y.

For x = 4:
y = 3(4) - 4
y = 12 - 4
y = 8

For x = 5:
y = 3(5) - 4
y = 15 - 4
y = 11

For x = 6:
y = 3(6) - 4
y = 18 - 4
y = 14

For x = 10:
y = 3(10) - 4
y = 30 - 4
y = 26

The completed table is:

x y
4 8
5 11
6 14
10 26
