35 : 10 = 7*5 : 2*5 = 7 : 2
Thus 35 : 10 = 7 : 2;
but 35:10 ≠ 7:5
ΔABC has the vertices A(0, 0), B(-8.5, 3), and C(0, 6), and ΔAXY has the vertices A(0, 0), X(-3, -8.5), and Y(-6, 0). Which tran

Rotation of ∆ABC counterclockwise about the origin by 90° will transform it to ∆AXY.
(x, y) ⇒ (-y, x)
Linear Regression is an approach for modeling the relationship between a scalar dependent variable y and one or more explanatory variables denoted x. the case of one explanatory variable is called simple linear regression
Factor the following:
x^2 - 36
x^2 - 36 = x^2 - 6^2:
x^2 - 6^2
Factor the difference of two squares. x^2 - 6^2 = (x - 6) (x + 6):
Answer: (x - 6) (x + 6)
Each side length was doubled. If you take the square root of 81 (9) and then the square root of 324 (18) you can see that each side was multiplied by 2
