fraction of games lost = 1 - = - =
number of games lost = of 42
= × 42 = 27
Answer:
1. x = 2
2. x = -2
3 x = 1
Step-by-step explanation:
Make x the subjects and work from there
These angles are same side interior angles. They add up to 180 degrees
Answer:
x = 0, - 2
Step-by-step explanation:
To find f(g(x)) , substitute x = g(x) into f(x)
f(x²) = 2x² + 1
To find g(f(x)) , substitute x = f(x) into g(x)
g(2x + 1) = (2x + 1)²
Then equating
(2x + 1)² = 2x² + 1 ← expand left side using FOIL
4x² + 4x + 1 = 2x² + 1 ( subtract 2x² + 1 from both sides )
2x² + 4x = 0 ← factor out 2x from each term on the left side
2x(x + 2) = 0
Equate each factor to zero and solve for x
2x = 0 ⇒ x = 0
x + 2 = 0 ⇒ x = - 2
solutions are x = 0, - 2
