Foundations of alegbra. When the sum of twice a number and 9 is divided by 3, the result is 7. What is the number? Write answer in a sentence.

But my teacher told me the answer is 6 I’m stuck on this I am not understanding how I keep getting different answer and my answers is not 6 please help me

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

Is appreciated! graph the functions and approximate an x-value in which the exponential function surpasses the polynomial function. f(x) = 4^xg(x) = 4x^2options: x = -1x = 0x = 1x = 2
