if u have a regular calculator, you cannot put y =, if u have a graphing calculator, then you press the "y =" button
If you put this equation in y-intercept form it is y=4/3x+20 If you have a graphing calculator just enter this in "y=" or graph it manually to find the x-intercept.
LCM is found by factoring, but then you must use all from each, with no repeatsFind LCM for 14x2y3z and 21 xy4factor 14x2y3 = 2.7 x x y y y zfactor 21 xy4 = 3.7 x y y y yfactors 2, 7, x , x , y, y, y, z, 3, y now multiply all theseso LCM = 2.7 x x y y y z . 3 y = 42x2y4zthis can give us a few rulesuse all numerical factorsuse all variable factors with the Largest exponent from each.
y=x+1
The y-intercept of y=3x+1 is at the point (0,1)(i worked it out on a graphics calculator my apologies if you needed working out.)

just put x^2=y or (x^2)/y on the calculator, and then it makes a simple parabola.
The empirical formula for the compound X3Y12 is X1Y4. This is determined by dividing the subscripts by the greatest common factor, which in this case is 3 for X and 12 for Y.

The way you find modulus of a number on a scientific calculator depends on the model of calculator. On the TI-86, you use mod (x,y) or x mod y to find modulus.

enter a value "x", press the "^" key, then enter the value you want to raise "x" to, "y". the calculator should show X^Y, for whatever you substituted. hit enter.

6xy=13 y=13/6x You may be confused at this point because your graphing calculator graphs a line when you plug in this equation. What your calculator is doing is (13/6)x=y which is indeed a line. However, you are working on inverse variations. Plug this into your calculator y=13/(6x) How is that different? Just look at the graph.
y = arcsin( cos 48 ); arcsin may be seen as sin-1 on your calculator.
