Can someone write me a short reflection on math subject this year? Not from Gooogle please​

7x+8y=-18, 4x-9y=-3 solve the system of equations

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212

Solve each quadratic equation by factoring and using the zero product property. 14x - 49 = x^2
