Answer:
area of square = l² = n²
Step-by-step explanation:
4.2x - 1.4y = 2.1 |multiply both sides by 10
42x - 14y = 21 |subtract 42x from both sides
-14y = 21 - 42x |change signs
14y = 42x - 21 |divide both sides by 14
y = 3x - 1.5
Answer:
slope 2 y intercept 2

<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 2x - 6
g(x) = 3x + 9
(f + g)(x) is f(x) + g(x)
<u>Step 2: Find</u>
- Substitute in function values: (f + g)(x) = 2x - 6 + 3x + 9
- Combine like terms: (f + g)(x) = 5x + 3
