Step-by-step explanation:
f(x) = 2 + 3x
f(4) = 2 + 3(4)
= 2 + 12 = 14
If the absolute value is bigger than one it's an expansion, less than 1 it's a contraction.
-2/3 - contraction
3.25 - expansion
5/8 - contraction
-3 - expansion

Answer:
x = 22
Step-by-step explanation:
The midsegment BF is half length of the base segment CE, so you have ...
2x = 88/2
x = 22 . . . . . divide by 2
<span> A: y=2x 15 (or whatever variables you choose to represent the colony growth and time)
B: y=2(3.5) 15;
22 colonies
C: substitute 584 with y into the original equation, so:
584=2x 15
569=2x
284.5=x; therefore, after 284.5 hours</span> Hope this helps! :D
