I NEED HELP Chuy tried to determine the solution for the system of equations using substitution. His work is shown below.

x – y = 7

3x – 2y = 8

Step 1: x = y + 7

Step 2: 3(y + 7) – 2y = 8

Step 3: 3y + 7 – 2y = 8

Step 4: y + 7 = 8

Step 5: y = 1

In which step did Chuy make the first error?

a

Step 1

b

Step 2

c

Step 3

d

Step 4

(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.

Which of the following statement about pascal's triangle are true?

Tcan be concluded that % of the seniors would prefer to see more candid pictures in this year's edition of the yearbook.
