⫸ Ratio, proportion, scaled, 'is to'. Ans: Proportion → a/b = c/d
⫸ slope formula. Ans: (y₂- y₁) / (x₂- x₁)
⫸ Quadratic Formula. Ans: x = -b ± √(b² - 4ac)/2a
⫸ exponent rules. Ans: a^n ⋅ a^m = a^n+m
a^n ⋅ b^n = (a ⋅ b)^n
a^n / a^m = a^n-m
a^n / b^n = (a / b)^n
(a^n)^m = a nxm
⫸ solving linear questions. Ans: ax+b=c (solve for X)
⫸ proportions. Ans: a/b=c/d
⫸ Percent Change. Ans: % change = [(new value - old value)/ old
value] x 100
