Answer:
f(-4) = -2
Step-by-step explanation:
To find f(-4) use the "piece" of the function rule defined for x < -3 (because -4 is less than -3). That part of the rule says the output (range) value is x + 2, so f(-4) = -4 + 2 = -2.
Answer:
16
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
y(y² + 4y + 16) - 4x(y² + 4y + 16) ← distribute both parenthesis
= y³ + 4y² + 16y - 4xy² - 16xy - 64x
Compare - axy to - 16xy ⇒ a = 16

Answer:
Each person paid $24.
Step-by-step explanation:
1. Find 20% of 40. Since 20% is equal to 1/5, we can divide 40 by 5 to get 8. Together they tipped $8.
2. We know that the total amount they paid was $48, so we divide that in half to get the answer. 48 divided by 2 is 24.
