I am trying to find out if my answer's are correct. Can someone please verify.
What is the equation for the line that passes through the (2,2) and has a slope of 5?
Answer
Y=5x + 2
Y=5x +12
Y=5x 2
None of these ¨C I believe this is the answer
Find the value of x^3+¡¼2x¡½^23 when x =3.
Answer 42
Solve 5x+3=13 for x.
Answer2
Compare the quantity in Column A with the quantity in Column B.
Column A Column B
The solution of The solution of
2(x3) = 6x 3x + 2 + 5x + 6
AnswerThe quantity of Column B is greater
Solve for x in x3 >8.
Answer
Compare the quantity in Column A with the quantity in Column B.
Column A Column B
6z5 if z=2 6z ¨C 5 if z = 2
AnswerThe quantities are equal

1. none of the given answers is correct
2. can't make out your typing
3. 5x 3 = 13
5x = 10
x = 2
4. ??
5. x3 >8
x3 > 8 or x + 3 > 8
x > 11 or x < 5
6. ???
7. your point doesn't satisfy your equation, you should have realized that by substituting it back in.
equation is y = 2x + b
plug in the given point (5,5)
5 = 10 + b
b = 5 , so ......... y = 2x  5can't make out your typing
8. can't make out your typing
9. your answer should be +9 , not 9
10. correct
11. 2x + 5 > 1
2x > 6
x > 3 , so none of the ones given

Find the value of x^3+¡¼2x¡½^23 when x =3.
I don't know how to type x to the 3rd power it keeps putting a little triangle there. How do I do this? When I type it here or in word it does the same thing. Help!

Typing here is done using the HTML codes. They are NOT the same as in Microsoft Word. If you copy and paste Microsoft Word documents, be sure that symbols show up correctly before and after you have sent your post.
x^3 means x to the third power, or you can type it as x³, or :
x & s u p 3 ;
but without the spaces between the characters.
What we do not understand are:
¡¼ and ¡½, do they actually mean ( and )?
