Step-by-step explanation:
- – 18q+10q+16q–3= – 19
- 8q=-19
- q=-19/8
- q=-2.375
Answer:

--- True
Step-by-step explanation:
Given



Solving (a): 
From the given parameters, we have:


So:

Collect like terms

Solving (b) m(x) = f(x) = g(x)?
In (a), we have:

And
--- given
By comparison:

Distance(Mercury, Sun) = 5.8 x 10^7
distance(Venus, Sun) = 1.1 x 10^8
distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7
The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.

simply subtract 5.8 from 11.0.
This gives us a result of 5.2 x 10^7.
Hope that makes sense!
