I don't know if this is right. directions: Simplify each radical expression. (radical 3+5)(radical 3-3) i think its: radical 3+2 Life would be so much simpler if you would use parenthesis. Did you mean this? (sqrt3 + 5)(sqrt3 -3) ? multiply that out sqrt3*sqrt3 -3sqrt3 +5s...

Directions are simplify by combining like terms. x radiacal 18 -3 radical 8x^2 can someone show me how to do these types of problems. thanks I cant determine the second term. For the first, I think you meant x sqrt(18) which reduces to x sqrt (9*3) or 3x sqrt 3 First remove sq...

this other one how can i actually prove it if this is the equation to use. the problem states: Prove that if a line has slope ma nd y-intercept b, then an equation of th eline is y=mx+b. then it says (Hint: use the point-slope equation theorem) I've looked at it but i unde...

okay i really don't understand this problem. It says: Prove the point-slope equation property which is : Point-slope equation(an nonvertical line with slope m and containing a point (X1,Y1) has the point-slope equation of y-y1=m(x-x1). Now show that any point (x2,y2) on th...

on a graph if a line is running verticle right on 5, then the slope of it would be x=5 yes thank you so much for all your help you are awsome.

the equation is and directions are: graph x-y=-2 so then the equation would really be: y=-x+2 and from here i would do the table to plot the points. Close. y=x+2, not -x+2. Then, yes, plot the points. so your saying that the equation that i have to graph would be: y= x+2 not y...

I aked the instructor about that problem that looked like this: (w-(1)/(4))^2 and he said that what i thought was right. which was : the answer:w^2-(1)/(2)w+(1)/(6) Yes, that's right. I just thought your way of getting the answer was more complicated than it could have bee...

Okay now i need explanation how to do these types of problems. Directions: Divide Problem: (7x^5y^5-21x^4y^4+14x^3y^3)/(7x^3y^3) Realize that you have 7x^3y^3 on the bottom. Now in order to get rid of that, you want to have the same thing in the top, multiplied by something el...

Thank you I did figure it out i think: so the problem was ((w)-(1)/(4))^2 The final answer that i got was w^2-(1)/(2)w+ (1)/(16) Sorry, no again. :) Make sure you really look at how to multiply binomials and FOIL them out. It will come back to haunt you. a lot. These are the s...

Directions: Find the slope of any line perpendicular to the line through points(0,5) and (-3,-4). THis is what i did. m=(-4-5)/(-3-0)=(9)/(3)=3 y=mx+b using points :(0,5) 5=3(0)+b 5=b y=3x+5 so the slope of the perpendicular line is (-1)/(3) When finding the slope, you got luc...
