16 pi inches squared brotha
Answer:
Range is (-9, -5, -1, 3).
Step-by-step explanation:
Work out f(x) for each value of x:
f(-3) = 2(-3) - 3 = -9
f(-1) = 2(-1) - 3 = -5
f(1) = 2(1) - 3 = -1
f(3) = 2(3) - 3 = 3
Step-by-step explanation:
m – 8 < 12
⇔
m < 12 + 8
⇔
m < 20

= .20
Next, multiply .20 × 91
= 18.2
To make it more accurate with money..
= $18.20

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
