associative property of multiplication

commutative property of multiplication

14: When finding the conjugate of a binomial, you must

keep the sign between the terms the same

change the sign between the two terms

there needs to be more information to answer this question

15: Jeff has one savings account with the interest rate of 3.3%, and one money market account with the interest rate of 5.1% in a bank. If he deposits $1200.00 to the savings account, and $1800.00 to the money market account, after 6 years he will have

1) Lines of symmetry

2) 2x - 3y = 3 and 4x - 2y = 10

Multiply first equation by two to get:

4x 鈥?6y = 6

Subtract this from the second equation to get:

4y = 4

y = 1

Sub this into either equation to get:

2x 鈥?3(1) = 3

2x = 6

x = 3

There the solution is (3, 1)

3) circumference

4) (1 + z) 脳 2 + 12 梅 3 - z when z = 4

(1 + 4) 脳 2 + 12 梅 3 - 4

= 5 脳 2 + 4 - 4

= 10 + 0

= 10

5) Standard deviation

6) 3x^2 -2x + 9 = 0

Divide by 3 to get:

x^2 鈥?2/3x + 3 = 0

The b term is -2/3

7) Volume of a rectangular prism = l x w x h

= 30 x 10 x 3

= 900

8) Not entirely sure, but I think it鈥檚 theoretical probability

9) Median 9.5 represents half of 8 and 11, which is the middle of the distribution

10) Expected value

11) 2(x + 5) - 7 = 3(x - 2)

2x + 10 鈥?7 = 3x 鈥?6

x = 9

12) 3 x 12 = 36

13) Distributive property

14) Change the sign between the two terms

15) Assuming this is simple interest, i.e. no compounding, then the calculations are:

Savings account interest = 1200 x 0.033 x 6 = 237.60

Money market interest = 1800 x 0.051 x 6 = 550.80

Total interest plus principal = 237.60 + 550.80 + 1200 + 1800 = 3788.40

16) Area = ? x ( b x h )

= ? x ( 8 x 5)

= 20

17) (3x + 5) (2x - 7)

= 6x^2 - 21x + 10x 鈥?35

= 6x^2 - 11x 鈥?35

18) 3x^2 + 5x + 2

= (3x + 2) (x + 1)

19) Supplementary

20) square root
