Answer:
y=4x and x+4y=12 are perpendicular because they have opposite reciprocal slopes
Step-by-step explanation:
y=4x slope is 4
x+4y=12 slope is -1/4
Sorry its hard to read and see
Answer:
y = 1.0535(4.9512)^x
It can be considered a viral video
Step-by-step explanation:
Using the exponential regression calculator, the regression model obtained is :
y = 1.0535(4.9512)^x
Using the model, we can determine if a video can be considered viral ;
Number of days, x = 10
y = 1.0535(4.9512)^10
y = 1.0535(8853290.1338)
y = 9,326,941.15
Hence, video will receive way over 3 million reviews, a review of about 9,326,941, hence, it can be considered a viral video.
Answer:
You can solve one by... it's hard to explain So i'll just show you
Step-by-step explanation:
Here's an example,
2x+7=4+5x
First you subtract the variables on both sides (lower variable)
2x+7=4+5x
-2x -2x
Which will leave you
7=4+3x
The subtract the whole number on each side (lower number)
7=4+3x
-4 -4
Which will leave you
3=+3x
Then you divide on both sides
3/3 3/3
which should leave you
x=1
