Answer:
-8 ≤ x ≤ 2
Step-by-step explanation:
We assume you intend the absolute value equation ...

Answer:
9,400 bacteria at Hour 17.
Step-by-step explanation:
If at
Hour 0, it was at 6,000 bacteria then at
Hour 6, it would be at 7,200 bacteria
That means in 6 hours, the bacteria has grown by 1,200
Let's use a ratio:
hours : bacteria
6 : 1,200
1 : 200
17 : 3,400
Now after 17 hours, 3,400 new bacteria has joined our group of 6,000
6000+3400=9400
9,400 bacteria should be present at Hour 17
Z

Z=kX
When x=6, z=18,
Finding value of z,
18=k*6
k=3
Z=3X
when x=10,
Z=3*10
Z=30
Part B;
Z

z=

Where x is a constant of proportionality,
when x=3, z=2
2=

a=3*2
a=6
When x is 13,
