Answer:
A
Step-by-step explanation:
Answer:
(f - g)(x) = -x² + 2x + 3
Step-by-step explanation:
Step 1: Define
f(x) = 2x + 3
g(x) = x²
(f - g)(x) = f(x) - g(x)
Step 2: Set up expression (Substitute)
(f - g)(x) = f(x) - g(x)
(f - g)(x) = 2x + 3 - x²
Step 3: Simplify
(f - g)(x) = -x² + 2x + 3
Answer:
y = 4
Step-by-step explanation:
2[2y-1]+5=19 (by PEDMAS, distribute parentheses first)
(2)(2y) - (2)(1) + 5 = 19
4y - 2 + 5 = 19
4y +3 = 19 (subtract 3 from both sides)
4y = 19 - 3
4y = 16 (divide both sides by 4)
y = 16/4
y = 4
