A)
x = -y -2
y = -x -2
B)
0.5x + y = 1
0.5x + (-x -2) = 1
-0.5x -2 = 1
-0.5x = 3
x = -6

Step-by-step explanation:
<u>Step 1: Define</u>
R(x) = 6x - 3
S(x) = -3x - 8
<u>Step 2: Find</u>
- Substitute in functions: R(x) - S(x) = 6x - 3 - (-3x - 8)
- [Distributive Property] Distribute negative: R(x) - S(x) = 6x - 3 + 3x + 8
- [Addition] Combine like terms: R(x) - S(x) = 9x + 5
Answer:
Option (C)
Step-by-step explanation:
Let the relation between amount of money (m) and Time (t) is represented by the equation,
m = ct + b
Where c = Investment per week
b = Ben already had the amount before investment
From the question,
c = $5 per week
b = $100
Therefore, equation will be,
m = 5t + 100
If duration of the investment 't' = 8 weeks
Amount in the account after 8 weeks,
m = 5(8) + 100
m = $140
Option (C) is the correct option.
