Answer:3.50x+40=57.50
They bought 5 movies
Step-by-step explanation:
Just draw a 3 by 2 block.to explain it you could say there is 2 groups of friends with each 3 people in it
Y = (-3/7)x + 4
Looking at the graph, you can see the trend line plotted. And conveniently, there are a couple of points on the trend line that are indicated. Those points being (0,4) and (7,1). The equation of a line in slope intercept form is:y = ax+b
Looking at the points available, the point (0,4) already gives us the y intercept since x is equal to 0. So our equation becomes:
y = ax + 4
Now we need to determine a which is the slope. The slope is the change in y divided by the change in x. So let's do that
(1-4)/(7-0) = -3/7
And now our equation becomes:
y = (-3/7)x + 4
And given formatting issues, the first option available is the correct one.
i think the answer is 8
bc the small one is 4 and the big one is 6
and the other one is 6 so it must be 8
