Find the linear approximation of the function f(x) = 1 − x at a = 0. l(x) = use l(x) to approximate the numbers 0.9 and 0.99 . (round your answers to four decimal places.) 0.9 ≈ 0.99 ≈ illustrate by graphing f and the tangent line.

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
