Help:) Factor f(x) = 4x^3+ 23x^2- 70x + 16 into linear factors given that - 8 is a zero of f(x).

Charra [1.4K]

Answer:

(x + 8)(x - 2)(4x - 1)

Step-by-step explanation:

Given that x = - 8 is a zero then (x + 8) is a factor

Divide f(x) by (x + 8) using Synthetic division

- 8 | 4 23 - 70 16

↓ - 32 72 - 16

---------------------------------

4 - 9 2 0

Quotient = 4x² - 9x + 2 = (x - 2)(4x - 1)

Thus

f(x) = (x + 8)(x - 2)(4x - 1)

The variables x and y are directly proportional, and y=2 when x=3. what is the value of y when x=9?

laiz [17]

X varies directly as y
x = ky
3 = 2k
k = $\frac{3}{2}$
when x =9
9 = $\frac{3}{2}$ y
$\frac{18}{3}$ = y
∴y = 6
