Answer:
18x
Step-by-step explanation:
get the x by itself then it is 2+4=6 so that is 6x and then do 3+x=3x and 6x×3x= 18x
The first answer is going to be 15.42 (so b) and the second is going to be 10.67 (so a)
A) T(m) = -0.16m +331.3
B) T(2015) = 8.9 . . . seconds
_____
The linear regression function of a graphing calculator can find the equation of the line easily. Or, you can use the 2-point form of the equation of a line.
.. T(m) = (10.5 -14.5)/(2005 -1980)*(m -1980) +14.5
.. T(m) = -0.16(m -1980) +14.5
