when x is 0, find y. plot the point (0, <<whatever you got>>).\nwhen y is 0, find x. plot the point (<<whatever you got>>, 0).\nConnect those two points, and extend the line.

y = 3/(1 - x)²\n\n1, (1 - x)² ≥ 0 for all x and therefore 3/(1 - x)² ≥ 0 for all x\n\n2. 3/(1 - x)² is undefined when x = 0. Therefore 3/(1 - x)² (ie y) → +∞ when x → 1 from the left of 1 and when x → 1 from the right of 1\n\n3. As x → ±∞, 3/(1 - x)² (ie y) → 0\n\n4. Plot a few other points and Bob's your uncle!!

y = mx + c\n(0) = (2)(-1) + c\nc = 2\n\ntherefore y = 2x + 2

2(y-3) = y-6\n\nThis is what you are supposed to calculate : a value for the y, such that the equation holds.\n\nfor instance try y = 1\n\n2(1-3) = 1-6\n2 - 6 = 1- 6\nand you see that this is not so, thus y=1 is not a solution.\n\nthe standard way to solve is : move all y''s to the left of the=, and all numbers to the right of the =\n\n2(y-3) = y - 6\n2y - 6 = y - 6\n2y -y - 6 = -6 ( move left y to the right, sign changes )\n2y - y = -6 + 6 moved left -6 to right, change sign\n\ny = 0. ( adding the 2y - y together, and the -6 + 6\n\nso the solution is y = o

y=1/x^2-3 => y+3 = 1/x^2 => x= +/-sqrt(1/(y+3))

Step 1: find y '\nStep 2: fill in x=1\nThat gives the right answer 2\n\nTh

Set it up: x=1/y which simplifies to x/y. So if y=30 when x=2, then 2/30=0.066667 When y=600, then x/600=0.066667; multiply 0.066667 by 600 for your answer of x=40. Good luck!

y=(3/4)x+11/4\n\nThe question asks to make a "function of x." That's like saying f(x). The function will be something were you plug a value for x and get another value.

c'mon dude, these are easy.\n\nAdd second to first.\n\n2x = 2, x = 1, therefore y = -2.

When you double a number, you just multiply it by 2.\ny = 2x\nx is the original number and y is the number after it's been doubled.

Y = U + VX^2\nVX^2 = Y - U\nX^2 = (Y-U)/V\nX = sqrt ( (Y-U)/V )

Since y = 9 when x=4,\nthen y=9/2 when x=4/2=2\n\nNo calculations required.\n\nBut if you must, this is done by Solving for k when x=4 and y=9\n9=4k+8\n4k=9-8\nk=1/4\n\nUsing k and x=2, then, y= 1/4(2) +4\n                       y= 1/2+4 =9/2

If x is 2, then 8x is 16.\n\nIf y is 3, then 4y is 12.\n\n16-12 is 4.  :o)
