Let a, b, c represent the numbers of subscribers who watched 1, 2, and 3 videos, respectively.
.. a +b +c = 312 . . . . . . . there are 312 subscribers, total
.. a +2b +3c = 740 . . . . there were 740 total views
Subtract double the first equation from the second.
.. (a +2b +3c) -2(a +b +c) = (740) -2(312)
.. c -a = 740 -624 = 116
116 more people watched all three videos than watched one video.
Answer:
The slope is 5/8.
Step-by-step explanation:
Use the slope formula:
m = y2 - y1 / x2 - x1
Plug in the numbers from the ordered pairs:
m = 8 - 3 / 13 - 7
m = 5/8
Answer:
Domain is { x> -15}
Range is { y >5}
Step-by-step explanation:
The domain is the possible x values
x is greater than -15 (open circle)
Domain is { x ≥ -15}
The range is the possible y values
y is greater than 5 (open circle)
Range is { y >5}
8/9 it the answer to the question
