Answer:
Step-by-step explanation:
The slope-intercept formula is:
y = m x + b,
or: y = b - m x, since the rate is negative.
For the 1st formula we have: y = 30 and x = 2
For the 2nd formula: y = 12 and x = 5 ( because: 5 = 2 + 3, or : 3 minutes later, which can be confusing )
30 = b - 2 m
12 = b - 5 m
--------------------
b = 30 + 2 m
12 = 30 + 2 m - 5 m
3 m = 18
m = 18 : 3 = 6
b = 30 + 2 * 6 = 30 + 12 = 42
Answer:
y = 42 - 6 x
Answer:
i THINK its 18.75% per year
Step-by-step explanation:
r = (1/8)((3,000/1200) - 1 ) = 0.1875
r = 0.1875 * 100 = 18.75
(dont take my word tho, u should double check yourself)
Answer:
well there is 60% girls
Step-by-step explanation:
40% are boys out of 100%
So what you have to do is find out what added by 40 is 100 which is 60 so it's
40% boys to 60% girls
Answer:
y = (4/5)x + 1
