Just multiply:\n(X/3)(3/4 x) -(x/3)(3/5) + (3/4)(3/4x) - (3/4)(3/5)\n\nand simplify from there

Okay, first, since the vector given for B is a unit vector, we know that the vector from the origin to B must be given by (some constant)*(2,-2,1)/3.  So, what you want to do is find the value of that constant such that |A-B|=10.  Do this by setting A-B=(6-2x/3, -2+2x/3, -4-x/3).  Then just find the length of that vector in terms of x, set it to 10, and solve for x.

do the multiplication first, then add the variables, then solve the equation by getting the variable to one side , remember, you move numbers by adding their opposite to both sides \n\n2(2.5b-9) + 6b=7\n5b - 18  +6b=7\n11b-18=7\n      +18  added to both side to move the -18\n11b=7 +18\n11b= 25\ndivide by -11 to both sides\nb=25/-11\n\nps: oops was that a .2 at the beggining? if so, the answer for the start would be \n.2(2.5b -9)\n.5b -.9

You need to use the quadratic equation...\n\nhttp://mathworld.wolfram.com/QuadraticEquation.html\n\nOR\n\nx (x - 5) = 0

____________________________________________________\n| \nBecause the bottom number is the same- X, so u add the top number-1+2, and u get 3. let me show you-- 1/x+2/x=3/x\nArent i right???!!!!!!!!!!

1. replace x with -3, calculate and see if you get 0\n2. divide by (x+3) and solve the remaining quadratic equation

1. Use a calculator\n2. Use successive approximation method\n\nXn+1 = ½ (Xn + N/Xn)\n\nEg Find √2\n\nTry X1 = 2 (Remember here N = 2)\n\nX2 = ½ (X1 + 2/X1)\n= ½ (2 + 2/2)\n= 1.5\n\nX3 = ½ (X2 + 2/X2)\n= ½ (1.5 + 2/1.5)\n= ½ (1.5 + 1.3333333333333....)\n= ½ (2.833333333333333.....)\n=1.411666666666666.....\n\netc ... and this is rapidly approaching 1.41421356 ..........\n\n3. Use the long division method which is difficult to describe on here but definitely works .....\n\n4. Reduce a number to the product of its primes. If all the indices of the prime factors are even, then the square root of the number is the primes multiplied together with all indices halved (actually this is true for all numbers but the fractional indices need interpretation and the result is a surd.)\n\neg √3969\n\n3969 = 3 x 1323\n= 3 x 3 x 441\n= 3² x 3 x 147\n= 3³ x 3 x 49\n= 3^4 x 7²\nSo √3969 = 3² x 7\n= 63

You figure the square root of each number separately...you've probably learned that in class alredy (how to do that)...then you take reach result, and multiply them together for your final answer.\n\nUse your textbook for reference...good luck!

You have to complete the square.\n\ny = a(x^2 + b/a x) + c\ny = a(x^2 +b/a x + b^2/4a^2) + c - b^2/4a\ny = a(x + b/2a)^2 + (4ac - b^2)/4a\n\n[4ay - (4ac - b^2)]/4a = a(x + b/2a)^2\n[4ay - 4ac + b^2]/(4a^2) = (x + b/2a)^2\n\n+/- sqrt(4ay - 4ac + b^2)/2a = x + b/2a\n\nx = (-b +/- sqrt(4ay - 4ac + b^2))/2a

Even though somebody told you the answer, I'm going to explain how to do it so you know on other problems. \n\n\n4(3y+2m+1)=\n\nYou have to take the number outside of the parenthesis, and multiply it to all the other numbers.\n\nFirst you do 4 x 3y, because 3y is the first term. \nThat comes out to 12y. \n\nThe next one is 2m, so 4 x 2m= 8m\n\nThe last term is 1, so 4 x 1=4.\n\nAdd up all the numbers and the answer comes out to 12y+8m+3\n\nApply the same method to the 2nd problem\nHope this helps!

try to follow\n\nx/2-10=a\na/2-4=b\nb/2-2=6\n\nsolve and substitue\nb=16\na=40\nx=100 --the original amount\n\nhope that helped

1.  Here you just divide both sides by 5 to get the x by itself\nand you get :\n5x<35\nx<7\n\n2. Divide both sides by 4\n4y>15\ny>15/4\n\n3.  Divide both sides by 16\n16y<64\ny<4\n\n4.  Divide both sides by a -18. Remember that you have to switch the equality sigh when you divide by a negative:\n-18y>-36\ny<2\n\n5. First, combine like terms (x):\n5x + 6x <-33\n11x<-33\nDivide both sides by 11:\nx<-3\n\n6. Combine like terms (y):\n-12>2y - 6y\n-12>-4y\nDivide by a -4. Remember to switch the equality sigh \n3<y\n\nHope that was helpful!

firt you work the problem in the parentheses. that would be (2*-5)+ 4. that would make it -10+4. that equals -6. then you take that and multiply it by -5. that gives you a positive 30

I figured it out... the answer is 1/(13*(2-3x))\nIf you need an explanation tell me

a) - Just substitute the numbers, so the problem becomes:-\n\n5+ 3(4-2) - (Do the sum in brackets first then multiply the answer by 3 then add the 5)\n\nb) - Y=3(x-5)(x-2) - Lose the brackets first by multiplyiny what's inside by eachother - (x-5)(x-2) - First multiply the xs, then the x in the first bracket by the 2 in the 2nd, then the minus 5 in the first bracket by the x in the 2nd, then the minus 5 in the 1st by the minus 2 in the 2nd. Add together the 4 terms and multiply by the 3 outside the brackets, and you should get to one of the options given.\n\n\n3) - Should be fairly obvious from the options given - Y = x+5 so Y is 5 greater than X \n\nHope this helps
