cud someone help a dumb girl?

Question

some questions-
1-absolute value of 2y+3 greater than 7
2-find an equation of the line containing the point (-1,4) and perpendicular to the line whose equation is x-y=6
3-multiply these complex #'s (3+2i)(4-7i)
4-express as a single logarithm: 2/3 log(small a) x-1/2 log(small a)+ 5 log(small a) z.
5-convert to an exponential equation: log(small a) c = 5
6- A pentagon with 5 sides congruent has a perimeter = to that of an octagon with all 8 sides congruent. one side of the pentagon is 2 less than 3x one side of the octagon. what is the perimeter of each figure?
7-real hard 1: Given f(x)=x^2 and g(x)=x+3, find
(f+g)(x), ff(x), fg(x), f (comp function) g(x), and g (cf) f(x)
thanks for all who answer, im stuck, cant you help a dumb girl out?++++please show the work, maybe ill get it thanks

Answer 1

"Please show your work, my teacher gives us "0" if we don't?"

That's more like it.

And that work is hardly difficult, maybe if you set your *** on fire you can complete it yourself.

Answer 2

You have to methodically go through the problems yourself. I would write down questions if you do not understand something. Also, write down what you understand about the problem. But, don't get stuck. If you can't get the answer in 10 minutes. Move on to the next one. But, don't just say you can't do it or you are dumb. That is not going to help you. Nobody starts out knowing anything. Attitude determines your altitude. You have to have more faith in yourself. Go back over the homework later and read your questions. Try to define what it is you are confused about. If you just say you are dumb or can't do it people will think you are lazy and don't try. There is no failure... only learning experiences.

Answer 3

First of all, you're not dumb.
This stuff takes lots of practice and effort. I remember when I first started doing these types of problems years ago. I was very confused but after trying every problem, having my dad and teacher find my mistakes and then doing them over again, I learned.
For #3 do you know FOIL .. Firs Outer Inner Last. You just multiply the terms in that order and then simplify.
Don't lose faith and remember! you're not dumb. you can do this.
Good Luck

Answer 4

|2y+3| > 7
Either 2y + 3 > 7 or 2y + 3 < -7
y>2 or y < - 5

If two lines are perp iff product of their slopes is -1
If m1 = 1
and m1*m2 = -1
then m2 = -1
y-4=-1*(x-(-1))
y = -x+3

remember i^2=-1
(3+2i)(4-7i)
= 12+8i-21i-14i^2
= 26-13i = 13* (2-i)

Ok you didn't copy problem 4 right the second term must be a log of something. I give up...

Answer 5

heavily.....If I got here homestead from artwork to discover little submit it notes giving me intructions like "bypass upstairs" "Get into mattress" etc and then my female friend walked in donning heavily eye-catching equipment and then were given into mattress for some warm relaxing....i might want to be made up! You dont might want to spend a penny to provide a romantic present!

Answer 6

Break this up into 7 separate questions. People are more likely to answer to get more points, and you might get better answers. Who knows?

Answer 7

How are you gonna learn anything if someone else is doing your homework for you?

Answer 8

Cheat on your homework much?

Answer 9

You actually think someone will do all that work for you!

Answer 10

You're not dumb you're just blonde.
