is a500×500sparse tri-diagonal matrix withbof your own choice, using ClassicalJacobi. Plot the iteration vs the norm of the residual in semilogy scale. Moreover, plotthe error convergence estimate using the spectral radius of the matrixM. In all methods, is the iteration process converging faster if the diagonal elements are changed to say -4or -10?

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

answer: 12

step-by-step explanation:

because yes

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
