Evaluate the expression.
131 +-5
Answers
To make it less confusing it’s just 131-5
Answer:
126
Step-by-step explanation:
131 + - 5 can either be;
131 + 5 = 136
131 - 5 = 126
The question is probably asking what is 131 plus negative 5, hence the correct equation is; 131 - 5, and the correct answer is 126.

Using two or more complete sentences, describe how you can find a vector parallel to B = (-2,3) .
Answers
Answer:
To find a vector parallel to B, such vector must be a scalar multiple of B.
Step-by-step explanation:
Two non-zero vectors are parallel if they are scalar multiples of one another.
A vector parallel to B must be a scalar multiple of B.
let the vector parallel to B be A, then their scalar multiple is given as;
A = kB
A = k(-2, 3)
where;
k is scalar
Thus, to find a vector parallel to B, such vector must be a scalar multiple of B.
