And #3 Find the distance from (3,8,-1) to  A)to the x-axis (round to two decimal) B) y-axis to two decimasl.?
415223
distance to x-axis is √(8² + (-1)²) = √65.\ndistance to y-axis is √(3² + (-1)²) = √10.\ndistance to z-axis is √(3² + 8²) = √73.

Option a: use one of the fancy calculators around nowadays.\nOption b:\nOk, we need at least a reasonable guess to get going. Lets draw a graph. But how do you draw a graph of 2cos(x) + x? We don't. We draw a graph of 2cos(x), and another graph of -x, and see where they are equal - because thats the point we're looking for. Don't forget to use radians, since you can't add a number to a degree.\nThe solution looks like it is around -1 or so. Now we can do a bit more guessing.\nPutting -1 into that equation gives 0.0806. Lets try -0.9. Whoops - that gives 0.34, which is getting even worse. How about -1.1? Ahha! That gives -0.19, so we know the answer is between -1.1 and -1.0.\nWe can keep narrowing it down in this way. Try -1.05: thats negative, so we're between -1.0 and -1.05. Try -1.02: thats positive, so we're between -1.02 and -1.05. Try -1.03: thats negative, but nearly 0. So we're between -1.02 and -1.03.\nWe're nearly there - try -1.025. thats positive, so we're done! We know the answer is between -1.025 and -1.03, so it must be -1.03 to the nearest 100th.\nThats quite a bit of work, but its not too bad. There are faster ways to do it, but they're a bit more complicated.

Subtract 8 from each side of the = sign and you have your answer\n\nx equals -11

T = F*d = I*alpha\n\nI = (1/3)*M*d^2\n\nIn both cases, d is the distance from the axis to "the outer edge of one pane",  "as shown in the drawing".

The first one is (-5, 3). I don't remember how to do the others.

7 - (-8) is 7+8  not 7+9.\n\nThe rule is an even number of negative signs gives a positive.  An odd number of negative signs gives a negative.\n\nThink of a line representing a coordinate axis. Put zero on the line. Then put on 1,2,3, etc. Each of them goes to the right.  Now put on -1, -2, -3, etc. Each of them goes to the left of where zero is.  now, what is the distance from +1 to +3.  It is 2, that is 3-1.  Now what is the distance from 1 to -3.  Count the spaces. It is 4. That is 1- (-3) = 1+3=4.\nFurther what is the distance between -1 and -3. Two spaces 2.  That is -1 - (_3) = -1 +3 = 2.

y>(12-3x)/4\n\nSteps:\n\nmultiply the 12 on both sides\n3x+4y>12\n\nminus the 3x isolating the y variable\n4y>12-3x\n\ndivide by 4 on both sides to get y by itself\ny>(12-3x)/4 or...\n\nsimplified 3-(3x/4)

8/x - 3/(x-1) =1\n1. Multiple x on both sides.\n8 - 3x/(x-1) = x\n\n2. Multiple (x-1) on both sides\n8(x-1) - 3x = x (x-1)\n\n3. Simplify\n8x - 8 - 3x = x^2 - x\nx^2 - 6x + 8 = 0\n\n4. Solve\n(x - 4)(x - 2) = 0\nx = 4 or x = 2
