Answer:
Step-by-step explanation:
Part A
In applying the synthetic division, the polynomial would be fully expressed as
2x³ + 0x² + 5x - 6
The coefficients are 2, 0, 5 and - 6
The working becomes
2| 2 0 5 -6
4 8 16
2 4 13 10
The student that correctly used synthetic division to find f(2) is Claudia
Part B
The value of f(2) is
2(2)^3+5(2) - 6
= (2 × 8) + 10 - 6
= 16 + 10 - 6 = 20
Part C
x - 2 is not a factor of 2x³ + 5x - 6 because there is a remainder of 20.
Part D
The methods that can be used to find out if x - 2 is a factor of 2x³ + 5x - 6 are synthetic division, long division, remainder theorem
Answer:
17
Step-by-step explanation:
f(x) = 3x + 2
f(5) = 3(5) + 2 = 17
Answer:
x = 7
Step-by-step explanation:
BD is an angle bisector of ∠ABC,
Therefore, by angle bisector theorem,
∠ABD ≅ ∠CBD
m∠ABD = m∠CBD
(2x + y) = (14 + y)
2x = 14
x = 7
Answer: 42 more ounces
Step-by-step explanation: 16 oz = 1 pound, so multiply 3 and 16, which gives you 48. 48 oz+9 oz=57 oz. 57 oz-15 oz= 42 oz.
