So I believe you go
and substitute x an y like this
(1-7) (7-1)
and get a slope of -9/6
Sorry If I got it wrong,but I hope I helped
Answer:
86
Step-by-step explanation:
Hello,
P(x)=x^3-7x-6
P(4)=4^3-7*4-6=30
Remainder=30
Answer: 46.05
Step-by-step explanation:
1/3 * 3.14 * 4 * 11 = 46.05 (rounded to the tenth)
Answer:
see explanation
Step-by-step explanation:
note when x = - 3
(- 3)³ + 2(- 3)² + 4(- 3) + 21 = - 27 + 18 - 12 + 21 = 0
hence x = - 3 is a zero and (x + 3) is a factor and dividing gives
= (x + 3)(x² - x + 7)
For zeros equate to zero
(x + 3)(x² - x + 7) = 0
equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x² - x + 7 = 0 ← solve using quadratic formula
x = (1 ± 
) / 2 = (1 ± 3i
) / 2
x = 
± 
zeros are x = - 3, x = ±
