21.) the sum of two consecutive integers is –49. write an equation that models this situation and find the values of the two integers.

a.) n + n + 1 = –49; n = –24; n + 1 = –23

b.) n + n + 1 = –49; n = –25; n + 1 = –26

c.) n + n + 1 = –49; n = –25; n + 1 = –24

d.) n + 2n = –49; n = –17; 2n = –34

The revenue generated by a bakery over x months, in thousands of dollars, is given by the function f(x) = 2(1.2)* the cost of running the bakery forx months, in thousands of dollars, is given by the function g(x) = 2x + 1.4determine the equation for h if h(x) = f(x) - g(x).oa. m(x) = (1-2)*-x-07b.(x) = 2(1 2 - 2x -0.7)h(x) = -2((1.2) + x + 0.7)d. h(x) = 2((12) - x-0.7)
