For vectors u=-6i +2k and v=7i-4j, find (-3u)*v. a) -450 b) -50 c) 108 d) 150 i know how to do these problems, but i am stuck on this question, because i keep finding the answer 118. i know you change -6i+2j to (-6,2) and 7i-4j to (7,-4) and then plug them into the equation but i don't know what i am doing wrong.

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
