Answer:
y = 4x + 8
Step-by-step explanation:
A linear formula always follows by y = mx + c, where m is the gradient and c is the y-intercept or constant.
Since you know that the slope is 4, all you need to do is find the y-intercept (constant)
y = 4x + c
Sub in the points (-4, -8)
-8 = 4(-4) + c
-8 + 16 = c
c = 8
Hence, y = 4x + 8
Answer:
Yes it is possible to have an increase of 100%.
Retail price is 83.4$
Step-by-step explanation:
250 = x + (200% of x)
250 = 300% of x
so basically 250$ = 3x
250/3 = 83.3333334
So you can round it to $83.4
Hope this helps. I'm not entirely sure this is true but I hope it is.
200/3% i think.... sorry if wrong

Answer:
Just input sin(9), sin(30), sin(81), etc.
For this set, you need a scientific calculator or else, you won't be able to answer that. There is a way but that is already obsolete now.
