Answer:
y = 3x + 1
Step-by-step explanation:
substitute the variables in y=mx+b
(5) = 3(-2) + b
5 = -6 + b
add 6 on each side
1 = b
Answer:
y+4=-5/2(x-3)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(6-(-4))/(-1-3)
m=(6+4)/-4
m=10/-4
m=-5/2
y-y1=m(x-x1)
y-(-4)=-5/2(x-3)
y+4=-5/2(x-3)
Answer:
Step-by-step explanation:
<em>Refer to picture.</em>
Let the distance to men are x and y and the distance between them is d.
The angle of depreciation is 27° and 30°, hence top angle of the triangle is 63° or 60°.
<u>Find the distance from the tower to men:</u>
- x = 20 tan 63° = 39.25 m
- y = 20 tan 60° = 34.64 m
<u>The distance between men is:</u>
- d =

<em>Note, all numbers are rounded</em>
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.
