Answer:
Step-by-step explanation:
so you can always put a 1 infront of a stand alone x making 1x + 6 - 6x + 10
i also like to do a little trick were you can change the subtraction sign to an addition if you make what you subtraction negitive
so we have 1x + 6 + -6x + 10
we can add 6 and 10 and 1x and -6x make an end result of
-5x + 16
(or the other way since it is addition)
Hi there!
Part A: Those groups of points that are circled and labeled A are called a correlation. In this case, the group of points represent negative correlation. The point that is labelled B is called an outlier, because it falls outside of the range of the other points. Point B may have been present like that, because while a person may spend a lot of time on social media, they might have understood the information very fast, or maybe they studied a bit on a different occasion.
Part B: Going back to part A, the graph represents a negative correlation. In this case, the more time spent on social media, the lower the test scores.

graph
y=3^(x-7)
y=2log(2x)
see where they intersect
we get at x=7.79
nearest tenth is 7.8
