At the market, joey buys 3 avocados for $0.40 each and 5 lemons for $0.40 each. the cashier in training rings up 3 × 0.40 and then 5 × 0.40 to get the total. the experienced cashier says to add the 3 plus 5 in his head and then ring up 8 × 0.40what property says that these two totals would be the same?

Choose the point slope form of the equation below that represents the like that passes through the points (-6,4) and (2, 0)

Iwant to know what 3g+5h+4g-2h is my teacher is too selfish to tell us

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .
