So your equation is m + 20 = 6
The first think you do is subtract 20 from both sides in order to get “m” alone, since that’s the variable you’re solving for. So what you’ll you have next is
m + 20 - 20 = 6-20
Since 20 subtracted by itself is zero, you’ll be left with
m + 0 = -14
Or more simply
m = -14
The answer is 2300 because the climbing rate is 100 bacteria per hour. so times 100 and 13 and u get 1300 and u have to add that to the a 1000
The function with the higgest rate of increase is 2^x
The 3 is a positive integer and the 7 is a negative integer so you would do "KFC" also known as (Keep, Flip, and Change)
3
("Keep" the 3 positive)
-
("Flip"the minus sign into a plus sign)
-7
("Change" the negative sign into a positive sign)
So therefore, you would have:
3 + 7, which equals 10
Let x = the number of hours since 5 a.m.
Let y = temperature, °F
Let the total temperature change be modeled by the expression
y = ax + b
At 5 a.m., x = 0 and y = -9.4°F. Therefore
b = -9.4
When x = 6 hours, y = 2.8°F. Therefore
6a + b = 2.8
6a - 9.4 = 2.8
6a = 12.2
a = 2.0333
The expression is
y = 2.0333x - 9.4
Answer:
y = 2.0333x - 9.4
where
x = hours since 5 a.m.
y = temperature, °F
