Solve the system by graphing.

{3y=2x−12y=−x−1
3y = 2x - 12 y = -x - 1

which ordered pair is the best estimate for the solution to the system?

question 4 options:

(2, -2.5)

(2.5, -2)

(1, -3)

(3, -3.5)

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).

2/3(-6y+9x) expand each expression using the distributive property
