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.

(x,y) (-x,-y)
y=x+1
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.
GCF is found by looking for common factors, real numbers or variables.Find GCF for 14x2y3z and 21 xy4factor 14x2y3z = 2.7 x x y y y zfactor 21 xy4 = 3.7 x y y y ycommon factors 7, x, y, y, y 3 y's in each but only 1 x , don't use z it is not in both terms ( it is not a common factor)multiply to get GCF 7xy3LCM is similar in that you start 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 rulesthe LCM is greater than (or equal to) the original termsbut the GCF is ledss than.Sounds backwards, but a factor is only one part, and even the greatest part is less than the whole.Also For LCM we use each variable with the LARGEST exponent.for the GCF we use only common variables, and use the SMALLEST exponent.All factors are NOT necessarily in the GCF ( notice 2, 3, and z above)But all factors are in the LCM
