Yes.
Expressions are just javascript, so they can access any global variables on the page.
The following works:
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
No, it doesn't matter. If they're equal, they're equal. It makes no difference whether I say "Ben is my son" or "My son is Ben".
if there are no comparison signs (equals or inequalities, ie =, >, < etc) then it is an expression, eg "x + 5" If there is a comparison sign which is not equals, then it is an inequality, eg "x > 5"
in the equation: y=mx+b , the y-intercept is represented by "b".
"Why is a constant a monomial?"The short answer is because a constant is a special typeof monomial.The reason for this is that the definition of a monomial reads: A monomial is"An expression that is eithera numeral (= a numerical expression which names a particular number, IE a constant),a variable,or a product of a numeral and one or more variables.""constant (monomial): A monomial consisting of a numeral only; a term with no variable factor. "
2VdV + 2PdP + 3T2dT (this is an expression, not an equation because there is no equals sign)
You're generally going to put the independent variable on the horizontal axis, ie the variable that you decided to change in the experiment. If it is a continuous variable (ie a run of numbers) then you will be plotting a line graph and joining with a line or curve of best fit. If your variable is categoric ie has labels rather than numbers, or if it is whole-number only, then you're going to be plotting a bar graph.
b = 40 - a, c = 42 - a so b + c = 40 - a + 42 - a, ie 82 -2a = 34 so a = 48/2 ie 24 b = 40 - 24 ie 16 and c = 42 - 24 ie 18
The dependent variable is monitored as the independent variable is changed. One is testing the effect of the independent variable on the dependent variable (ie effect of dissolved HClO on pH).
18 + 70 ie 87
5s - 6 = 2s, ie 5s - 2s = 6, ie 3s = 6, ie s = 2
3600/48 ie 75%
