A ratio that shows the number of letters in the word below that have a vertical line of symmetry HOUSTON?
5 letters: HOUTO are vertically symmetrice. 2 (S and N) are not.
What is the definition of the symbol s?
The symbol S on the periodic table stands for Sulfur.
Why does the dollar sign have a line through the S?
actually, it has 2 lines through it unlike on the keyboard where it has one. no on knows for sure
How do you do linear equations with two points?
Suppose you have the points with coordinates (p, q) and (r, s) then, provided p is different from r, the slope of the line is (q - s)/(p - r) = m, say. Then, if (x, y) is any point on the line, (x - s)/(y - r) = m That, after simplification, is the linear equation of the line. This will be a lot simpler when you have numerical values for p, q, r and s rather than work algebraically throughout. If p is not different from r, then the equation is x = p (or r), a vertical line.
How would you graph an inequalities x-s less than or equal to y?
Mark a point on the x-axis as 's', then draw a solid line through this point, with a slope of 1. Then shade in the area above this line. The region above the line is shaded because if x-s < y then y > (x-s). The line is drawn as a solid line to represent that it can be equal, as well. At the point x=s, y = 0, which is where you marked s on the x-axis.
