Answer:
f(x) = .8 (215 - .45 x)
f(x) = .8 (215 - .45 * 75) = .8 ( 215 - 34) = .8 (181) = 145
Answer:
i think -2.5 -0.3 0.261 2.1
For this case, we must find the triangle whose value of x is given by 17.
In all three cases, the value of the variable "x" is given by:
Triangle 1:
Triangle 2:
Triangle 3:
Thus, the triangle whose value of x is 17 is triangle 2.
