Answer:
The function f(x) is represented by:

Hence, a=1500 and b=0.97
Step-by-step explanation:
The patient currently has a bone density of 1,500 kg/mg^3.
A doctor estimates that a particular patient is losing bone density at a rate of 3% annually.
This means that the bone density that is remaining is:
100-3=97%
which is also represented as: 97%=97/100=0.97
Hence, the function f(x) that represents the bone density after x years is represented by:

where a is the initial bone density which is given to be: 1500 kg/mg^3.
Hence, the function is:

I only know 1 & 4 .. 2 & 3 seem hard to me ..
X >7
X< -7

Add all the numbers
Divide by 9
Answer:
9) 28
10) 22
Step-by-step explanation:
collinear means on the same line
9 ) AB+BC=AC
16+12=28
10) 13+9=22
