Notice this is in slope-intercept form.
1 is the y-intercept
1/3x is the slope
find 1 on the y-intercept and mark the spot, then use the slope to plot more points. Plot at least three to be sure your line is right. to use the slope 1/3,
you need to start at your first mark and go up 1 and to the right 3 then mark that spot and do it again and draw a line through the points!
Hope this helps!

understand???

For x^4-10x^2+9 we need to factor it to (x^2-9)(x^2-1)
Then factor x^3+4x^2+3x
Since there is an x in each term we can factor it out
x(x^2+4x+3)
We need to factor both top and bottom more.
(x^2-9)(x^2-1)= (x+3)(x-3)and(x+1)(x-1)
x(x^2+4x+3)= x(x+3)(x+1)
then you can cancel out terms that are the same in top and bottom.
We cancel out (x+3) and (x+1) in the top and bottom to get an answer of:
(x-3)(x-1)/x

I belive this is how to solve your equation.
11x(x+3)=0
then you have to make each term equal to zero:
11x=0 x+3=0
for 11x=0 you divide by 11 on both sides which equals 0. x=0
then for x+3=0 you subtract 3 from both sides to get x by itself.
x= -3
Then you want to check the answers in the original problem to see if they are right!
Hope this helps!

Use the FOIL method to find the product.
You need to multiply the firsts, outers, inners, and lasts.
(2x+6)(x-10)
the firsts are, 2x(x)=2x^2
the outers are, 2x(-10)=-20x
the inners are, 6(x)=6x
the lasts are, 6(-10)=-60
THEN..you need to add like terms.
2x^2-20x+6x-60=
2x^2-14x-60
You can factor this more, but I am not sure if that's what you need to do. You can e-mail me and let me know if you need more help.

-3x^2= 9x
because -3x times -3x= a positive 9x
So: 0=9x+5x
Then we need to solve for x
9x=0 divide both sides by 9
x=0
5x=0 divide both sides by 5
x=0
I'm not sure if this is the answer you are looking for, but this is what I would do with this problem.
Hope it is right!!

I don't care for word problems either, but this one is actually pretty simple.
You should divide 240 by 20=12
the answer to this is the answer to your problem.
12 inches on the map connects the two cities.

If you are trying to find the value of c:
You did the first part right. Now you need to combine like terms.
20c-12c=8c
18+12=30
(your equation should look like this)
8c+30=110
then we need to isolate the variable,so..
subtract 30 from both sides of the equal sign.
8C=80
then divide both sides by 8
80 divided by 8 is 10
So c=10
Hope this helps!!

1/5 is = to 20%
so, you multiply 45.50 by 20%
45.50*20%=9.10
Then you subract 9.10 from 45.50
45.50-9.10=36.40
So the sale price is $36.40
