LET US SEE:\n\n1. y = (1/2)x + 5. This is an equation in standard form.\nIt is called slope-intercept form. If you mean general form\nthen:\n\ny = (1/2)x + 5\n\nMultiply by 2:\n2y = x + 10\n\n0 = x - 2y + 10\n\nx - 2y + 10 = 0  ANSWER\n\n=======================\n2. Line parallel to y = (1/4)x + 2:\n\nAny line parallel to y = (1/4)x + 2 has the equation:\ny = mx + b  ===> Equation of line\nwhere:\nm = slope = same as slope of given parallel line = 1/4\n\ny = (1/4)x + b ANSWER (equation of parallel lines)\n\nex:\na) y = (1/4)x + 0\nb) y = (1/4)x + 1\nc) y = (1/4)x + 3\nd) y = (1/4)x + 4\nd) y = (1/4)x - 1\ne) y = (1/4)x - 2\n.\n.\n.\n\n=======================\n\n3. y varies directly as x ; y = 2/3 and x = 1/2.\n\ny = kx (direct variation equation) where:\nk = constant of variation\n\nif y = 2/3 and x = 1/2:\n\ny = kx\n2/3 = k(1/2)\nk = (2/3)/(1/2)\nk = (2/3)(2/1)\nk = 4/3\n\nTherefore:\n\ny = (4/3)x ANSWER\n\n=======================\n4. Line passing thru (0,2) and perpendicular to \ny = (1/4)x + 2\n\nLet m = slope = -4 = negative reciprocal to slope\nof perpendicular line.\n\ny = mx + b  ==> slope-intercept form, where:\n\nm = slope\nb = y-intercept\n\nSolving for b, use point (0,2)\n\ny = mx + b\n2 = -4(0) + b\n2 = 0 + b\nb = 2\n\nTherefore, equation is:\n\ny = -4x + 2 ANSWER\n\n=======================\n\n5) Point(s) that lie on the graph of the equation \n\n3x + 6y = 27.\n\nThese are points that will make the left side of \nthe equation equal to 27.\n\nEX. ...;(-5,7)(-3,6)(-1,5);(1,4);(3,3);(5,2);(7,1);...\n\n=============================\n6. Equation of the line that contains (2,4) and undefined slope.\n\nA line that has an undefined slope is a vertical line. So,\na vertical line that contains (2,4) has the equation:\n\nx = 2  same as the x-coordinate of the given point.\n\n===========================\n\n7. Equation of the line that passes thru the x-axis \nat x = -1 and y-axis at y = 3.\n\nFrom the given intercepts, the two points are (-1,0)\nand (0,3)\n\nTherefore:\n\ny = mx + b ===> equation in slope intercept form.\nwhere:\nm = slope = (3-0)/(0--1) = 3/1 = 3\nb = y-intercept from point (0,3) = 3\n\nTherefore:\n\ny = mx + b\n\ny = 3x + 3 ANSWER.

Problem 1:\n\n1912.50/45,000 = x/60,000\n45,000x=60,000*1912.50\n45,000x=114750000\nx=114750000/45000\nx=2550\n\nProblem 2:\n(2000/3 = 3300/x)*2\n(2000x=9900)*2\n(x=9900/2000)*2\n(x=4.95)*2\nx=9.9 seconds\n\nThese solutions are solving for x algebraically, but are the long way.\n\nAs mentioned above, an easier way is to figure the percentage of each and then multiply.\n\nSo $1,912.50 divided by $45,000 = .0425.  Multiply this by $60,000 (60,000*.0425) = $2,550.\n\nThe same can be applied to the number of seconds.\nIt takes 3 seconds to print 2000 characters...3/2000 = .0015 (or 1 character every .0015 seconds).  Then multiply this by 3300 to get the time for 1 page = 4.95 seconds.  Then multiply by 2 to get the time for two pages: 4.95*2 = 9.9 seconds.

1. Xc = 1/2πfC\nSo 2πfC = 1/Xc\nSo C = 1/2πfXc\n\n2. ib = ibq + √2is\nSo √ = ib - ibq\nSo 2is = (ib - ibq)²\nie is = ½(ib - ibq)²\n\n3. Q = XL/R\nSo XL = QR\n\n4. Lt = L1 + L2 - 2Lm\nSo 2Lm = L1 + L2 - Lt\nie Lm = ½(L1 + L2 - Lt)\n\n5. R1=i2 R2 / i2\n??????? So R1 = R2\n\n6. Es = E1 + E2 + E3\nSo E2 = Es - E1 - E3\n\n7. R1 / Rx = R2 / R3\nSo Rx / R1 = R3 / R2\nSo Rx = R1 * R3/R2\n\n8. y = Mx + b\nSo Mx = y - b\nSo M = (y - b)/x\n\n9. i2=i1 R1 / R2\nSo i1 R1 = i2R2\nie i1 = i2 R2 / R1\n\nI would be extremely concerned about your progress if you find this simple algebra a serious chore!!!!!! (Especially if you are learning the electrical trade)

16/24....it's really not that hard...you should be able to solve it on your own.\nps. you might want to simplify it down to 2/3.

Try reviewing your class notes and looking through your text book. Im sure that the answer you need is there. It might take a bit of thought to figure out how to do these problems! Take the time to figure it out, it will be worth it in the long run!

because this has 2 unknowns it cannot be solved.\n\nbut I can write  x in terms of b\n\n2x = 13-b\nor x =(13-b)/2

1) -2 x (2/5 -2p)\n    =4/5+4p            after multiplying through by -2\n\n2) 1 x (9/20 -p)\n    =9/20-p              after multiplying through by +1\n\nThis has started you off you should be able to solve now!

Plug in each of the four answers.  The only one that works is (2), because you get\n\n | 3 (-2/3) - 3 | = 5\n | -2 - 3 | = 5\n | -5 | = 5\n 5 = 5

Multiply or divide all components in one question to set the variables in the opposite questions to cancel out if you added the two problems together by combining like terms. For example:\n2x + 3y = -13  and 4x + y = -1\n\nTo keep this simple I will multiply all the components of the 2x + 3y = -13 equation by negative 2, resulting in:\n\n-4x - 6y = 26\n\nThen add the new equation to the other equation 4x + y = -1\n\n-4x -6y = 26\n4x + y = -1\n----------------\n0x -5y = 25  which simplifies to y = -5\n\nInsert the value found for y back into one of the original eqations and solve for x\n\n2x + 3(-5) = -13\n\n2x + -15 = -13\n\n2x = 2\n\nx = 1\n\nYour end result is x =1 and y = -5

Go to their website and you might be able to get the answers. Or if you have the book, they have all of the odd answers in the back of the book.  (Or if you have an older sibling who's really good at math, they can help a lot!)
