Answer:
15k³ - 9k² - 54k + 24
Step-by-step explanation:
(3k - 6)(5k² + 7k - 4)
distribute parentheses
= 3k * 5k² + 3k * 7k + 3k(-4) + (-6) * 5k² + (-6) * 7k + (-6)(-4)
apply minus - plus rules: + (-a) = -a, (-a)(-b) = ab
= 3 * 5k²k + 3 * 7kk - 3 * 4k - 6 * 5k² - 6 * 7k + 6 * 4
simplify: 3 * 5k²k + 3 * 7kk - 3 * 4k -6 * 5k² - 6 * 7k + 6 * 4:
= 15k³ - 9k² - 54k + 24
x×1/2×1/4×3/4
x×3/32
3/32x
Answer
-1
Just plug in the numbers.
(X,5)
Since y-intercept is the y-coordinate, it would be (X,5)
60,000/ -30,000 (read explanation)
8% of 10,000 is 800, 800 x 50(years) = 40,000, 100,000 -40,000 = 60,000, I believe you meant 100,000, cause if not, the answer is -30,000
Hope this helped
