algebra 2 assistance?

Question

1.evaluate 6^0+6^1+6^2

2.{8} < (with the line under it).{7,8,9}
true or false
*and im not sure because usually a greater
less than sign has this<>.. BUT this sign looks like a c with a line under it.*

3. A( intersection sign that looks like a wide lower case ) 0 with slash threw it = A

true or false.

4. 1/5^-2=25
true or falsse

5. simplify
32a^3b^2
_______
8ab^2

and please help..

6. simplify
5(2x-3)+4(x+1)

Answer 1

Question 1
6^0 + 6^1 + 6²
1 + 6 + 36
43

Question 2
8 ≤ 7 is FALSE

Question 3
Not sure what you mean.

Question 4
1 / 5^(-2) = 5² = 25
TRUE

Question 5
4 a² is answer

Question 6
10x + 15 + 4x + 4
14x + 19

Answer 2

# 1 = 1 + 6 + 36 = 43 because any number to the 0 power is 1
its a common misconception that aNumber^0 = 0....it doesn't it = 1....dont belie me google 6^0


#2, you are dealing with sets and intersections.....find out what the sign is, i doubt it is less than or equal to...its is prolly a union or intersection sign....if you know what that sign means that prob is easy

#3 google what an intersection sign looks like in discrete mathematics

#4 a negative exponent means that you can flip the fraction and change the sign

so 1/(5 ^ -2) == 5^2 which = 25 so it is true


#6 10x -15 + 4x + 4 == 14 x -11

multiply it out using the FOIL rule. and combined like terms.



#2 and 3 are more discrete mathematic oriented... its not really alg II

Hope that helps ya.

Answer 3

1) 1 + 6 + 36 = 43 (fixed...sorry I wasn't paying attention. The other guy had it right)

4) true

5) 4 a^2

6) 10x - 15 + 4x + 4 = 14x - 11

I can't quite understand 2 and 3...try looking in the character map on windows to find the right symbols.

Answer 4

1. ( 2x - 5) ( x + 3 ) if you use the foil method you will get 2x^2 + x - 15 2. skip 3. Y= mx + b, M is always you slope, and B is y intercept therefore making your point of interception (0,-7) thus it will be parallel to the x-axis and located 7 units below it

Answer 5

This is beyond help. You're asking us to do your homework.
And what are you doing in Algebra II if you can't evaluate at least #1?
You need to talk to your instructor.
