Which sequence is modeled by the graph below? points are (1,3) (2,0.6) (3, 0.12) a an = 3 (one fifth )^n − 1 b an = 3(−5)^n − 1 c an = 0.3(5)^n − 1 d an = one fifth (3)^n − 1

[15 points]find the least common multiple of the expressions: 1. 3x^2, 6x - 18 2. 5x, 5x(x +2) 3. x^2 - 9, x + 3 4. x^2 - 3x - 10, x + 2 explain if possible

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!

Plz answer asap! i will reward brainliest and 12 points for these three questions!take notice: these three questions are completely different! 1) what is the percentage of sugar in the syrup made of 10 kg of water and 4 kg of suugar? 2) what was the original price if after 10% discount it became $450? 3) at first a price was decreased by 12%, then it was disounted again by an additional 5%. what is the percent of the total discount? , and remeber i will award brainliest and 12 points!
