Let vector a = <1,-4> and vector b = <-1,-3>. Find negative vector a + vector b. I've tried adding <1+-1,-4+-3> = <0,-7> but that was apparently wrong so I have no idea what I'm supposed to do in this question​

Find a number such that if you add 8 and divide the result by 4 you will get the same answer as if you subtracted 3 from the original number and divided by 2

Graph g(x)=2cosx . use 3.14 for π . use the sine tool to graph the function. graph the function by plotting two points. the first point must be on the midline and closest to the origin. the second point must be a maximum or minimum value on the graph closest to the first point.

Consider the input and output values for f(x) = 2x - 3 and g(x) = 2x + 7. what is a reasonable explanation for different rules with different input values producing the same sequence?
