Answer:
Which one do we have to answer?
Step-by-step explanation:
First of all, I can't even see the whole question. Second of all, you didn't tell us what to answer. Please comment on this answer on which question you need help with.
X + y = 1
x + 3y = 9
Subtract the second equation from the first.
-2y = -8
divide both sides by -2
y = 4
Plug 4 back into either equation and solve for x.
x + y = 1
x + 4 = 1
subtract 4 from each side
x = -3
(-3, 4)
I'm not sure what you are looking for but I'll answer this question based on what I think is needed.
Given:
Day 1: 130
Day 2: 130 x 4 = 520
Day 3: 520 x 4 = 2,080
The exponential equation of this problem is:
V(n) = 130(4)^n
Where n is the number of days since the video was first shown.
Let us assume that 10 days have past. Total view would be:
V(n) = 130(4)^n
V(10) = 130(4)^10
V(10) = 130(1,048,576)
V(10) = 136,314,880
After 10 days, there are more than 136 Million views of the viral video.
