What is 4x +y=10 when x=minus2 It says write the ordered pair?

Replace x with -2:\n4(-2)+y=10\n-8+y=10\n\nAdd 8 to both sides:\ny=18\n\nThe ordered pair is (-2,18)\n\nThe ordered pair means to find the x and y values.\n\nCheck:\n4(-2)+18=10\n-8+18=10\n10=10

y = mx + b\n\nCharge = $2(x) + $10\nx = number of rentals\n\ny = 2x + 10

ok\nso its factoring.this is hella easy.10x+40 is 10(x+4)\nso the answer is 10(x+4)there you go

The - before the parenthases negates the signs of whats in there.\nx-(4-x)=0 becomes x-4+x=0 \nAdd the 4 to both sides and add the x's together.\nx-4+x=0 becomes 2x=4\nDivide both sides by 2.\n2x=4 becomes x=2.\nTo check plug the 2 in for x.\n2-(4-2)=0 becomes 2-2=0

To figure this out, you need to know that an ordered pair is in the form: (x, y). Just take each ordered pair and stick it into the equation:\na) 3(1) = 2(-1) -1 ... 3 = -3 (Not correct.)\nb) 3(-1) = 2(-1) - 1 ... -3 = -3 (Correct.)\nc) 3(-2) = 2(-5/2) - 1 ... -6 = -6 (Correct.)\nd) 3(0) = 2(-1/2) - 1 ... 0 = -2 (Not correct.)\n\nSo, the correct answers are (b) and (c).

x+4(2x+1)=3( x-2)+10x : x=2.5\n\nI like to work with x

(y+10)^2-72=0 \n(y+10)^2 = 72\ny+10 = +- sqrt(72)\ny= -10 +- sqrt(72)\n-10 + sqrt(72), -10 - sqrt(72)\ns

y = x^2 + 5x - 3\n2y=3x - 2\n----------------\n2y = 2x^2 + 10x - 6\n2y = 3x - 2\n-----------------------\n    0 = 2x^2 + 7x - 4\n=>2x^2 + 7x - 4 =0\n=>2x^2 + 8x - x - 4 = 0\n=>2x(x + 4) -1(x+4) = 0\n=> (2x - 1)(x + 4) = 0\ntherefore 2x - 1 = 0 => x = 1/2 or \nx + 4 = 0 or x = -4\nx = - 4 or 1/2  \ngot it?

okay well pretty much you have to solve for  x\nso inorder to get X by itslef you have to -4 from -8 like so:\n2x + 4-4 = –8-4\n2x=-12\nnow you still have 2X but now you can divide the 2 into -12\nx= \nI won't give you the answer but you should be able to find the answer!!!

4x + (x + 2) ....... 4x + 2 is 4 times a number plus 2 and it's incorrect

IF you mean like an ordered pair it is a point on a graph.  An example is:  (x,y)  so you can have (3,5)  or (-7,-88)  Otherwise I'm not sure what you're talking about.

4. \nquad 1 = (x,y)\nquad 2 = (-x,y)\nquad 3 = (-x,-y)\nquad 4 = (x,-y)

x+y=8\nx-y=-4\n______\n2x=4 (because +y and -y cancel out)\nx=2\nthen plug 2 in for x in one of the equations\n2+y=8\nsolve for y\ny=6\nordered pair is (2, 6)

when playing with < and >\nif you multiply all the equation by -1 the sign < changes to >, and the sign > changes to <\nbut if you just switch the number on the other side the sign doesnt change\nin ur case :\n2x-y < 4 \nequals\n-y < -2x + 4\nif you multiply it with -1 it will become\ny > 2x - 4\n\nlike that. hope it helps :)

Well you must have two equations! If you wanted to say x+4y=16 then just add the two and you'll fing x (4x=10) and then find y from one of them.

Rewrite the equations as:\ny = -x + 2 and\ny = (x+10)/2 = 1/2*x +5\n\nNow, if you insert x=0 in each equation, you will get a y-value.\nIf you insert y=0 in each equation, you will get an x-value.\nFor each line, you can use those two intercepts to graph the line.
