If the endpoints of MN have coordinates of M (2,7) and N (-3,1), then the length of MN is closest to (1) 6.1 (3) 7.5

(2) 6.7 (4) 7.8

This is very confusing to me I really need help

Which matrix can be multiplied to the left of a vector matrix to get a new vector matrix ?

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

1c) the number 131 is a term in the sequence defined by the explicit rule f(n)=5n-4. which term in the sequence is 131? 2a) write the first four terms of the function f(n)=n^2-1 2b) what is the 10th term of the sequence defined by the explicit rule f(n)=n^2-1 2c) the number 224 is a term in the sequence defined by the explicit rule f(n)=n^2-1. which term in the sequence is 224?
